Offering end of life support as part of home care is important – but may face some challenges

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/jennifer-tieman-378102">Jennifer Tieman</a>, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a></em></p> <p>Earlier this month, the government announced <a href="https://theconversation.com/the-government-has-a-new-plan-for-residential-aged-care-heres-whats-changing-238765">major changes</a> to aged care in Australia, including a A$4.3 billion <a href="https://theconversation.com/what-the-governments-home-care-changes-mean-for-ageing-australians-238890">investment in home care</a>.</p> <p>Alongside a shake up of home care packages, the Support at Home program will include an important addition – an <a href="https://www.health.gov.au/sites/default/files/2024-09/support-at-home-fact-sheet.pdf">end of life pathway</a> for older Australians.</p> <p>This pathway will allow access to a <a href="https://www.health.gov.au/our-work/support-at-home/features">higher level</a> of in-home aged care services to help Australians stay at home as they come to the end of their life. Specifically, it will provide an extra A$25,000 for palliative support when a person has three months or less left to live.</p> <p>This is a positive change. But there may be some challenges to implementing it.</p> <h2>Why is this important?</h2> <p>Older people have made clear their preference to remain in their homes as they age. For <a href="https://journals.sagepub.com/doi/10.1177/0269216313487940">most people</a>, home is where they would like to be during their last months of life. The space is personal, familiar and comforting.</p> <p>However, data from the <a href="https://www.abs.gov.au/statistics/research/classifying-place-death-australian-mortality-statistics">Australian Bureau of Statistics</a> shows most people who die between the ages of 65 and 84 die in hospital, while most people aged 85 and older die in residential aged care.</p> <p>This apparent gap may reflect a lack of appropriate services. Both palliative care services and GPs have an important role in providing medical care to people living at home with a terminal illness. However, being able to <a href="https://grattan.edu.au/wp-content/uploads/2014/09/815-dying-well.pdf">die at home</a> relies on the availability of ongoing support including hands-on care and assistance with daily living.</p> <p>Family members and friends often provide this support, but this is not always possible. Even when it is, carers may <a href="https://pubmed.ncbi.nlm.nih.gov/38533612/">lack confidence and skills</a> to provide the necessary care, and may not have enough support for and respite from their carer role.</p> <p>The palliative care funding offered within Support at Home should help an older person to remain at home and die at home, if that is their preference.</p> <p>Unless someone dies suddenly, care needs are likely to increase at the end of a person’s life. Supports at home may involve help with showering and toileting, assessing and addressing symptoms, developing care plans, managing medications, wound dressing, domestic tasks, preparing meals, and communicating with the person’s family.</p> <p>Occupational therapists and physiotherapists can assist with equipment requirements and suggest home modifications.</p> <p>End of life supports may also involve clarifying goals of care, contacting services such as pharmacists for medications or equipment, liaising with organisations about financial matters, respite care or funeral planning, as well as acknowledging grief and offering spiritual care.</p> <p>But we don’t know yet exactly what services the $25,000 will go towards.</p> <h2>What do we know about the scheme so far?</h2> <p>The Support at Home program, including the end of life pathway, is scheduled to start from <a href="https://www.health.gov.au/sites/default/files/2024-09/support-at-home-fact-sheet.pdf">July 1 2025</a>.</p> <p>We know the funding is linked to a prognosis of three months or less to live, which will be determined <a href="https://www.abc.net.au/news/2024-09-15/new-payment-aims-to-make-it-easier-for-people-to-die-at-home/104347984">by a doctor</a>.</p> <p>Further information has indicated that an older person can be referred to a <a href="https://www.health.gov.au/our-work/support-at-home/features">high-priority assessment</a> to access the end of life pathway. We don’t know yet what this means, however they don’t need to be an existing Support at Home participant to be eligible.</p> <p>The pathway will allow 16 weeks to use the funds, possibly to provide some leeway around the three-month timeline.</p> <p>Although more details are coming to light, there are still some things which remain unclear.</p> <p>Home care providers will be looking for details on what can be covered by this funding and how they will work alongside primary care providers and health-care services.</p> <p>Older people and their families will want to know the processes to apply for this funding and how long applications will take to be reviewed.</p> <p>Everyone will want to know what happens if the person doesn’t die within three months.</p> <h2>Some challenges</h2> <p>Ready availability of appropriate supports and services will be crucial for older people accessing this pathway. Home care providers will therefore need to assess how an end of life pathway fits into their operational activities and how they can build the necessary skills and capacity.</p> <p>Demand for nurses with palliative care skills and allied health professionals is likely to increase. Providing end of life care can be <a href="https://pubmed.ncbi.nlm.nih.gov/33096682/">especially taxing</a> so strategies will be needed to prevent staff burnout and encourage self-care.</p> <p>How pathways are implemented in rural and remote areas and in different cultural and community groups will need to be monitored to ensure all older people benefit.</p> <p>Effective coordination and communication between home care, primary care and specialist palliative providers care will be key. Digital health systems that connect the sectors could be helpful. Family engagement will also be very important.</p> <p>Escalation pathways and referral pathways should be established to enable appropriate responses to emergencies, unexpected deterioration, and family distress.</p> <p>Finally, <a href="https://bmcpalliatcare.biomedcentral.com/articles/10.1186/s12904-023-01155-y">accurately determining</a> when someone will die can be difficult. Knowing when the last three months of life starts may not be easy, particularly where frailty, cognitive issues and multiple health concerns may be present.</p> <p>This might mean some people are not seen as being ready for this pathway. Others may not be willing to accept this prognosis. An older person may also be expected to live with a terminal illness for many months or years. Their palliative care needs would not be met under this pathway.</p> <p>Despite these challenges, the announcement of an end of life pathway within the home care program is timely and welcome. As a population we are living longer and dying older. More details will help us be better prepared to implement this scheme.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/239296/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/jennifer-tieman-378102">Jennifer Tieman</a>, Matthew Flinders Professor and Director of the Research Centre for Palliative Care, Death and Dying, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Are young people smarter than older adults? My research shows cognitive differences between generations are diminishing

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/stephen-badham-1531316">Stephen Badham</a>, <a href="https://theconversation.com/institutions/nottingham-trent-university-1338">Nottingham Trent University</a></em></p> <p>We often assume young people are smarter, or at least quicker, than older people. For example, we’ve all heard that scientists, and even more so mathematicians, <a href="https://www.forbes.com/sites/nextavenue/2014/08/07/who-says-scientists-peak-by-age-50/">carry out their most important work</a> when they’re comparatively young.</p> <p>But my new research, <a href="https://www.sciencedirect.com/science/article/pii/S027322972400008X#:%7E:text=Highlights&text=Three%20review%20studies%20measure%20secular,%2C%20education%2C%20and%20overall%20health.">published in Developmental Review</a>, suggests that cognitive differences between the old and young are tapering off over time. This is hugely important as stereotypes about the intelligence of people in their sixties or older may be holding them back – in the workplace and beyond.</p> <p>Cognitive ageing is often measured by comparing young adults, aged 18-30, to older adults, aged 65 and over. There are a variety of tasks that older adults do not perform well on compared to young adults, such as memory, spatial ability and speed of processing, which often form the basis of <a href="https://theconversation.com/the-iq-test-wars-why-screening-for-intelligence-is-still-so-controversial-81428">IQ tests</a>. That said, there are a few tasks that older people do better at than younger people, such as reading comprehension and vocabulary.</p> <p>Declines in cognition are driven by a process called <a href="https://www.nature.com/collections/cbjacdabdf">cognitive ageing</a>, which happens to everyone. Surprisingly, age-related cognitive deficits start very early in adulthood, and declines in cognition have been measured as dropping in adults as young as just 25.</p> <p>Often, it is only when people reach older age that these effects add up to a noticeable amount. Common complaints consist of walking into a room and forgetting why you entered, as well as difficulty remembering names and struggling to drive in the dark.</p> <h2>The trouble with comparison</h2> <p>Sometimes, comparing young adults to older adults can be misleading though. The two generations were brought up in different times, with different levels of education, healthcare and nutrition. They also lead different daily lives, with some older people having lived though a world war while the youngest generation is growing up with the internet.</p> <p>Most of these factors favour the younger generation, and this can explain a proportion of their advantage in cognitive tasks.</p> <p>Indeed, much existing research shows that <a href="https://theconversation.com/iq-tests-are-humans-getting-smarter-158837">IQ has been improving</a> globally throughout the 20th century. This means that later-born generations are more cognitively able than those born earlier. This is even found when both generations are tested in the same way at the same age.</p> <p>Currently, there is growing evidence that <a href="https://www.pnas.org/doi/10.1073/pnas.1718793115">increases in IQ are levelling off,</a> such that, in the most recent couple of decades, young adults are no more cognitively able than young adults born shortly beforehand.</p> <p>Together, these factors may underlie the current result, namely that cognitive differences between young and older adults are diminishing over time.</p> <h2>New results</h2> <p>My research began when my team started getting strange results in our lab. We found that often the age differences we were getting between young and older adults was smaller or absent, compared to prior research from early 2000s.</p> <p>This prompted me to start looking at trends in age differences across the psychological literature in this area. I uncovered a variety of data that compared young and older adults from the 1960s up to the current day. I plotted this data against year of publication, and found that age deficits have been getting smaller over the last six decades.</p> <p>Next, I assessed if the average increases in cognitive ability over time seen across all individuals was a result that also applied to older adults specifically. Many large databases exist where groups of individuals are recruited every few years to take part in the same tests. I analysed studies using these data sets to look at older adults.</p> <p>I found that, just like younger people, older adults were indeed becoming more cognitively able with each cohort. But if differences are disappearing, does that mean younger people’s improvements in cognitive ability have slowed down or that older people’s have increased?</p> <p>I analysed data from my own laboratory that I had gathered over a seven-year period to find out. Here, I was able to dissociate the performance of the young from the performance of the older. I found that each cohort of young adults was performing to a similar extent across this seven-year period, but that older adults were showing improvements in both processing speed and vocabulary scores.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/591482/original/file-20240501-24-esxcic.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/591482/original/file-20240501-24-esxcic.png?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=333&fit=crop&dpr=1 600w, https://images.theconversation.com/files/591482/original/file-20240501-24-esxcic.png?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=333&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/591482/original/file-20240501-24-esxcic.png?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=333&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/591482/original/file-20240501-24-esxcic.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=418&fit=crop&dpr=1 754w, https://images.theconversation.com/files/591482/original/file-20240501-24-esxcic.png?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=418&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/591482/original/file-20240501-24-esxcic.png?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=418&fit=crop&dpr=3 2262w" alt="The figure shows data for a speed-based task where higher scores represent better performance." /><figcaption><span class="caption">The figure shows data for a speed-based task where higher scores represent better performance.</span> <span class="attribution"><a class="license" href="http://creativecommons.org/licenses/by-sa/4.0/">CC BY-SA</a></span></figcaption></figure> <p>I believe the older adults of today are benefiting from many of the factors previously most applicable to young adults. For example, the number of children who went to school <a href="https://education-uk.org/history/chapter12.html">increased significantly</a> in the 1960s – with the system being more similar to what it is today than what it was at the start of the 20th century.</p> <p>This is being reflected in that cohort’s increased scores today, now they are older adults. At the same time, young adults have hit a ceiling and are no longer improving as much with each cohort.</p> <p>It is not entirely clear why the young generations have stopped improving so much. Some research has <a href="https://doi.org/10.1016/j.intell.2016.10.002">explored maternal age, mental health and even evolutionary trends</a>. I favour the opinion that there is just a natural ceiling – a limit to how much factors such as education, nutrition and health can improve cognitive performance.</p> <p>These data have important implications for research into dementia. For example, it is possible that a modern older adult in the early stages of dementia might pass a dementia test that was designed 20 or 30 years ago for the general population at that time.</p> <p>Therefore, as older adults are performing better in general than previous generations, it may be necessary to revise definitions of dementia that depend on an individuals’ expected level of ability.</p> <p>Ultimately, we need to rethink what it means to become older. And there’s finally some good news. Ultimately, we can expect to be more cognitively able than our grandparents were when we reach their age.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/229132/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/stephen-badham-1531316">Stephen Badham</a>, Professor of Psychology, <a href="https://theconversation.com/institutions/nottingham-trent-university-1338">Nottingham Trent University</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

New studies suggest millions with mild cognitive impairment go undiagnosed, often until it’s too late

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/soeren-mattke-1484707">Soeren Mattke</a>, <a href="https://theconversation.com/institutions/university-of-southern-california-1265">University of Southern California</a> and <a href="https://theconversation.com/profiles/ying-liu-1221170">Ying Liu</a>, <a href="https://theconversation.com/institutions/usc-dornsife-college-of-letters-arts-and-sciences-2669">USC Dornsife College of Letters, Arts and Sciences</a></em></p> <p>Mild cognitive impairment – an early stage of dementia – is widely underdiagnosed in people 65 and older. That is the key takeaway of two recent studies from our team.</p> <p>In the first study, we used Medicare data for about 40 million beneficiaries age 65 and older from 2015 to 2019 to estimate the prevalence of mild cognitive impairment in that population and to identify what proportion of them had actually been diagnosed.</p> <p>Our <a href="https://doi.org/10.1186/s13195-023-01272-z">finding was sobering</a>: A mere 8% of the number of cases with mild cognitive impairment that we expected based on a statistical model had actually been diagnosed. Scaled up to the general population 65 and older, this means that approximately 7.4 million cases across the country remain undiagnosed.</p> <p>In the second study, we analyzed data for 226,756 primary care clinicians and found that <a href="https://doi.org/10.14283/jpad.2023.131">over 99% of them underdiagnosed mild cognitive impairment</a> in this population.</p> <h2>Why it matters</h2> <p>Mild cognitive impairment is an early symptom of Alzheimer’s disease in <a href="https://doi.org/10.1001/jama.2019.2000">about half of cases</a> and progresses to dementia <a href="https://www.alz.org/alzheimers-dementia/what-is-dementia/related_conditions/mild-cognitive-impairment">at a rate of 10% to 15% per year</a>. It includes symptoms such as losing the ability to remember recent events and appointments, make sound decisions and master complex tasks. Failure to detect it might deprive patients of an opportunity to get treated and to slow down disease progression.</p> <p>Mild cognitive impairment can sometimes be caused by easily addressable factors, such as medication side effects, thyroid dysfunction or <a href="https://theconversation.com/vitamin-b12-deficiency-is-a-common-health-problem-that-can-have-serious-consequences-but-doctors-often-overlook-it-192714">vitamin B12 deficiency</a>. Since mild cognitive impairment has <a href="https://doi.org/10.1016/j.amjopharm.2008.06.004">the same risk factors as cardiovascular disease</a>, such as high blood pressure and cholesterol, medication management of these risks combined with diet and exercise <a href="https://doi.org/10.1016/S0140-6736(15)60461-5">can reduce the risk of progression</a>.</p> <p>In 2023, the Food and Drug Administration <a href="https://www.fda.gov/news-events/press-announcements/fda-converts-novel-alzheimers-disease-treatment-traditional-approval">approved the drug lecanemab</a> as the <a href="https://theconversation.com/what-the-fdas-accelerated-approval-of-a-new-alzheimers-drug-could-mean-for-those-with-the-disease-5-questions-answered-about-lecanemab-197460">first disease-modifying treatment</a> <a href="https://www.nia.nih.gov/health/alzheimers-causes-and-risk-factors/what-happens-brain-alzheimers-disease">for Alzheimer’s disease</a>, the most common cause of mild cognitive impairment. In contrast to previous drugs, which can temporarily improve symptoms of the disease, such as memory loss and agitation, this new treatment addresses the underlying cause of the disease.</p> <p>Lecanemab, a monoclonal antibody, <a href="https://www.news-medical.net/health/What-are-Amyloid-Plaques.aspx">reduces amyloid plaques</a> in the brain, which are toxic protein clumps that are believed to contribute to the progression of the disease. In a large clinical trial, lecanemab was able to <a href="https://doi.org/10.1056/NEJMoa2212948">reduce the progression</a> of early-stage Alzheimer’s disease. A similar drug, donanemab, also <a href="https://doi.org/10.1001/jama.2023.13239">succeeded in a clinical trial</a> and is expected to be <a href="https://www.medicalnewstoday.com/articles/fda-delays-approval-of-alzheimers-drug-donanemab-what-experts-think">approved sometime in 2024</a>.</p> <p>However, these drugs must be used in the early stages of Alzheimer’s disease, ideally when a patient has only mild cognitive impairment, as there is <a href="https://www.alz.org/alzheimers-dementia/treatments/lecanemab-leqembi">no evidence that they are effective in advanced stages</a>.</p> <figure><iframe src="https://www.youtube.com/embed/w3IbAscNjsQ?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">An earlier diagnosis leads to early treatment and better outcomes.</span></figcaption></figure> <h2>What still isn’t known</h2> <p>Many factors contribute to the <a href="https://doi.org/10.1002/alz.13051">lack of timely detection</a>. But researchers don’t have a good understanding of the relative importance of those individual factors or how to reduce the high rate of underdiagnosis.</p> <p>While distinct, symptoms are subtle and their slow progression means that they can be overlooked or misinterpreted as normal aging. A neurologist in China told our research team that diagnosis rates spike in China after the New Year’s holiday, when children who haven’t seen their parents for a year notice changes that are harder to pick up when interacting with someone daily.</p> <p>Doctors also commonly discount memory concerns as normal aging and doubt that much can be done about it. While cognitive tests to distinguish mild cognitive impairment from pathologic decline do exist, they take about 15 minutes, which can be hard to come by during the limited time of a doctor’s visit and may require a follow-up appointment.</p> <h2>What’s next</h2> <p>People, particularly those in their 60s and beyond, as well as their families and friends need to be vigilant about cognitive decline, bring it up during doctor’s appointments and insist on a formal assessment.</p> <p>The <a href="https://www.medicare.gov/coverage/yearly-wellness-visits">Medicare yearly “wellness” visit</a> is an opportunity to explore such concerns, but only about half of beneficiaries <a href="https://doi.org/10.1377/hlthaff.2019.01795">take advantage of it</a>.</p> <p>Just as physicians ask patients about unexplained weight loss and take those concerns seriously, we believe questions that explore a patient’s cognitive state need to become the norm.</p> <p><em>The <a href="https://theconversation.com/us/topics/research-brief-83231">Research Brief</a> is a short take on interesting academic work.</em><img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/216892/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/soeren-mattke-1484707">Soeren Mattke</a>, Director of the USC Dornsife Brain Health Observatory, <a href="https://theconversation.com/institutions/university-of-southern-california-1265">University of Southern California</a> and <a href="https://theconversation.com/profiles/ying-liu-1221170">Ying Liu</a>, Research Scientist, Center for Economic and Social Research, <a href="https://theconversation.com/institutions/usc-dornsife-college-of-letters-arts-and-sciences-2669">USC Dornsife College of Letters, Arts and Sciences</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

94-year-old grandma takes on huge travel challenge

<p>"Grandma Joy" Ryan was 91 when she first got her passport, and she hasn't stopped travelling since. </p> <p>Now aged 94, she is embarking on a new global challenge with her grandson Brad Ryan, 42, with the intergenerational duo planning to travel to all seven continents in the world together. </p> <p>"I don't have many years left, [so] you hop to it," Grandma Joy told <em>CNN Travel</em>. </p> <p> "If you slow down, you don't get anything done."</p> <p>The pair, who are from the US, have already travelled to three continents, visiting Banff National Park in Canada last year to "represent North America well beyond just our own country", and Africa in 2023, visiting both Amboseli National Park and Maasai Mara National Reserve in Kenya. </p> <p>Their most recent trip was to South America, where they travelled to Ecuador, and spent time in the Galapagos Islands, as well as Chile. </p> <p>"It was amazing to see those huge tortoises," Grandma Joy recalled. "They could raise their shells up just like a convertible or something."</p> <p>Prior to travelling the world together, the grandma-grandson duo were actually estranged for around a decade due to a family rift that occurred after Ryan's parents divorced. </p> <p>After reconnecting in 2010, Ryan was telling his grandma about his previous hiking adventures on the Appalachian Trail and Mount Kilimanjaro, when he learnt that his grandmother "had never set eyes on a mountain."</p> <p>"That was one of her lifelong regrets," he said. </p> <p>"Her travel had been limited to just a few road trips to Florida with my grandfather when he was alive.</p> <p>"Her view of the world was always what she saw on the Travel Channel or just on the news."</p> <p>That conversation stuck with him and the pair embarked on their first journey together in 2015, when Ryan decided to take a weekend road trip to the Great Smoky Mountains National Park. </p> <p>"At 85, she saw her first mountain, climbed her first mountain and went camping for the first time and fell off the air mattress a couple of times and didn't complain," he said. </p> <p>He added, that having to move more slowly as he was travelling with his grandma, meant that he was able to appreciate everything in a more meaningful way. </p> <p>"I wasn't rushing through the places that I was visiting. I was really taking the time to appreciate smaller details.</p> <p>"The lens through which she is seeing the world is very different to most people my age. She doesn't visit a place thinking, 'Well, I'll be back again,' so there's more presence."</p> <p>They kept the adventure going and decided to travel to the 62 other US National Parks, and while it took them almost eight years with two-month long breaks between each trip, Grandma Joy made history last year. </p> <p>She became the oldest person to visit all 63 National Parks in the US. </p> <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/p/CsU_w4-rqyP/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/p/CsU_w4-rqyP/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by Grandma Joy’s Road Trip — Brad and Joy Ryan (@grandmajoysroadtrip)</a></p> </div> </blockquote> <p>"Being an old person sitting on the porch, this makes you feel like, 'Well maybe I did accomplish something.'

Can a daily multivitamin improve your memory?

<p><a href="https://theconversation.com/profiles/jacques-raubenheimer-1144463">Jacques Raubenheimer</a>, <em><a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em><a href="https://theconversation.com/au/topics/research-check-25155">Research Checks</a> interrogate newly published studies and how they’re reported in the media. The analysis is undertaken by one or more academics not involved with the study, and reviewed by another, to make sure it’s accurate.</em></p> <hr /> <p>Don’t we all want to do what we can to reduce the impact of age-related decline on our memory?</p> <p>A new study suggests a daily multivitamin and mineral supplement is a simple and inexpensive way to help older adults slow the decline in some aspects of memory function.</p> <p>The <a href="https://ajcn.nutrition.org/article/S0002-9165(23)48904-6/fulltext">new study</a>, which comes from a <a href="https://www.clinicaltrials.gov/ct2/show/NCT02422745?term=NCT02422745&draw=2&rank=1">long-running clinical trial</a>, shows there may be a small benefit of taking a daily multivitamin and mineral supplement for one type of cognitive task (immediate word recall) among well-functioning elderly white people. At least in the short term.</p> <p>But that doesn’t mean we should all rush out and buy multivitamins. The results of the study don’t apply to the whole population, or to all types of memory function. Nor does the study show long-term benefits.</p> <h2>How was the study conducted?</h2> <p>The overarching COSMOS study is a well-designed double-blind randomised control trial. This means participants were randomly allocated to receive the intervention (a daily multivitamin and mineral supplement) or a placebo (dummy tablet), but neither the participants nor the researchers knew which one they were taking.</p> <p>This type of study is considered the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5654877/">gold standard</a> and allows researchers to compare various outcomes.</p> <p>Participants (3,562) were older than 64 for women, and 59 for men, with no history of heart attack, invasive cancer, stroke or serious illness. They couldn’t use multivitamins or minerals (or <a href="https://www.pnas.org/doi/10.1073/pnas.2216932120">cocoa extract</a> which they also tested) during the trial.</p> <p>Participants completed a <a href="https://www.clinicaltrials.gov/ct2/show/NCT04582617?term=NCT04582617&draw=2&rank=1">battery of online cognitive tests</a> at the start of the study (known as baseline), then yearly for three years, of which only three were reported in this paper:</p> <ul> <li> <p>ModRey, measuring immediate recall. Participants were shown “a list of 20 words, one at a time, for three seconds each,” and then had to type the list from memory</p> </li> <li> <p>ModBent, measuring object recognition. Participants were given 20 prompts with a shape and then had to select the correct match from a pair of similar prompts. After this, they were prompted with 40 shapes in turn, and had to indicate whether each was included in the original 20 or not</p> </li> <li> <p>Flanker, measuring “executive control”. Participants had to select a coloured block that corresponded to an arrow in a matrix of arrows, which could have the same (or different) colour to the surrounding arrows, and the same (or different) direction as the prompt block.</p> </li> </ul> <h2>What did the researchers find?</h2> <p>Of all the tests the researchers performed, only immediate recall (ModRey) at one year showed a significant effect, meaning the result is unlikely to just be a result of chance.</p> <p>At two and three years, the effect was no longer significant (meaning it could be down to chance).</p> <p>However they added an “overall estimate” by averaging the results from all three years to arrive at another significant effect.</p> <p>All the effect sizes reported are very small. The largest effect is for the participants’ immediate recall at one year, which was 0.07 – a value that is <a href="https://academic.oup.com/jpepsy/article/34/9/917/939415">generally considered very small without justification</a>.</p> <p>Also of note is that both the multivitamin and placebo groups had higher immediate word recall scores at one year (compared to baseline), although the multivitamin group’s increase was significantly larger.</p> <p><a href="https://www.pnas.org/doi/epdf/10.1073/pnas.2216932120">In the researchers’ prior study</a>, the increase in word recall scores was described as a “typical learning (practice) effect”. This means they attributed the higher scores at one year to familiarisation with the test.</p> <p>For some reason, this “learning effect” was not discussed in the current paper, where the treatment group showed a significantly larger increase compared to those who were given the placebo.</p> <h2>What are the limitations of the study?</h2> <p>The team used a suitable statistical analysis. However, it did not adjust for demographic characteristics such as age, gender, race, and level of education.</p> <p>The authors detail their study’s major limitation well: it is not very generalisable, as it used “mostly white participants” who had to be very computer literate, and, one could argue, would be quite well-functioning cognitively.</p> <figure class="align-center "><figcaption></figcaption>Another unmentioned limitation is the advanced age of their sample, meaning long-term results for younger people can’t be assessed.</figure> <p>Additionally, the baseline diet score for their sample was abysmal. The researchers say participants’ diet scores “were consistent with <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/1899558">averages from the US population</a>” but the cited study noted “the overall dietary quality… [was] poor.”</p> <p>And they didn’t measure changes in diet over the three years, which could impact the results.</p> <h2>How should we interpret the results?</h2> <p>The poor dietary quality of the sample raises the question: can a better diet be the simple fix, rather than multivitamin and mineral supplements?</p> <p>Even for the effect they observed, which micronutrient from the supplement was the contributing factor?</p> <p>The researchers speculate about vitamins B12 and D. But you can find research on cognitive function for any arbitrarily chosen <a href="https://www.centrum.com/content/dam/cf-consumer-healthcare/bp-wellness-centrum/en_US/pdf/lbl-00000775-web-ready-centrum-silver-adults-tablets-(versio.pdf">ingredient</a>, including <a href="https://scholar.google.com/scholar?hl=en&as_sdt=0%2C5&q=selenium+cognitive+function">selenium</a>, which can be <a href="https://www.sciencedirect.com/science/article/pii/S0048969720378608">toxic at high levels</a>.</p> <h2>So should I take a multivitamin?</h2> <p><a href="https://newsinhealth.nih.gov/2013/08/should-you-take-dietary-supplements">Health authorities advise</a> daily multivitamin use isn’t necessary, as you can get all the nutrients you need by eating a wide variety of healthy foods. However, supplementation may be appropriate to meet any specific nutrient gaps an individual has.</p> <p>Using a good quality multivitamin at the recommended dose shouldn’t do any harm, but at best, this study shows well-functioning elderly white people might show some additional benefit in one type of cognitive task from using a multivitamin supplement.</p> <p>The case for most of the rest of the population, and the long-term benefit for younger people, can’t be made.</p> <hr /> <h2>Blind peer review</h2> <p><strong>Clare Collins writes:</strong></p> <p>I agree with the reviewer’s assessment, which is a comprehensive critique of the study. The key result was a small effect size from taking a daily multivitamin and mineral (or “multinutrient”) supplement on memory recall at one year (but not later time points) and is equivalent to a training effect where you get better at taking a test the more times you do it.</p> <p>It’s also worth noting the study authors received support and funding from commercial companies to undertake the study.</p> <p>While the study authors state they don’t believe background diet quality impacted the results, they didn’t comprehensively assess this. They used a brief <a href="https://pubmed.ncbi.nlm.nih.gov/22513989/">diet quality assessment score</a> only at baseline. Participants may have changed their eating habits during the study, which could then impact the results.</p> <p>Given all participants reported low diet quality scores, an important question is whether giving participants the knowledge, skills and resources to eat more healthily would have a bigger impact on cognition than taking supplements. <img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/208114/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em>Image credit: Shutterstock</em></p> <p><em><a href="https://theconversation.com/profiles/jacques-raubenheimer-1144463">Jacques Raubenheimer</a>, Senior Research Fellow, Biostatistics, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What is cognitive functional therapy? How can it reduce low back pain and get you moving?

<p><em><a href="https://theconversation.com/profiles/peter-osullivan-48973">Peter O'Sullivan</a>, <a href="https://theconversation.com/institutions/curtin-university-873">Curtin University</a>; <a href="https://theconversation.com/profiles/jp-caneiro-1463060">JP Caneiro</a>, <a href="https://theconversation.com/institutions/curtin-university-873">Curtin University</a>; <a href="https://theconversation.com/profiles/mark-hancock-1463059">Mark Hancock</a>, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a>, and <a href="https://theconversation.com/profiles/peter-kent-1433302">Peter Kent</a>, <a href="https://theconversation.com/institutions/curtin-university-873">Curtin University</a></em></p> <p>If you haven’t had lower back pain, it’s likely you know someone who has. It affects <a href="https://pubmed.ncbi.nlm.nih.gov/22231424/">around 40% of adults</a> in any year, ranging from adolescents to those in later life. While most people recover, <a href="https://pubmed.ncbi.nlm.nih.gov/29112007/">around 20%</a> go on to develop chronic low back pain (lasting more than three months).</p> <p>There is a <a href="https://bjsm.bmj.com/content/54/12/698">common view</a> that chronic low back pain is caused by permanent tissue damage including “wear and tear”, disc degeneration, disc bulges and arthritis of the spine. This “damage” is often described as resulting from injury and loading of the spine (such as bending and lifting), ageing, poor posture and weak “core” muscles.</p> <p>We’re often told to “protect” our back by sitting tall, bracing the core, keeping a straight back when bending and lifting, and avoiding movement and activities that are painful. Health practitioners often <a href="https://theconversation.com/having-good-posture-doesnt-prevent-back-pain-and-bad-posture-doesnt-cause-it-183732">promote and reinforce these messages</a>.</p> <p>But this is <a href="https://bjsm.bmj.com/content/54/12/698">not based on evidence</a>. An emerging treatment known as <a href="https://pubmed.ncbi.nlm.nih.gov/29669082/">cognitive functional therapy</a> aims to help patients undo some of these unhelpful and restrictive practices, and learn to trust and move their body again.</p> <h2>People are often given the wrong advice</h2> <p>People with chronic back pain are often referred for imaging scans to detect things like disc degeneration, disc bulges and arthritis.</p> <p>But these findings are very common in people <em>without</em> low back pain and research shows they <a href="https://pubmed.ncbi.nlm.nih.gov/24276945/">don’t accurately predict</a> a person’s current or future experience of pain.</p> <p>Once serious causes of back pain have been ruled out (such as cancer, infection, fracture and nerve compression), there is <a href="https://pubmed.ncbi.nlm.nih.gov/27745712/">little evidence</a> scan findings help guide or improve the care for people with chronic low back pain.</p> <p>In fact, scanning people and telling them they have arthritis and disc degeneration can <a href="https://pubmed.ncbi.nlm.nih.gov/33748882/">frighten them</a>, resulting in them avoiding activity, worsening their pain and distress.</p> <p>It can also lead to potentially harmful treatments such as <a href="https://pubmed.ncbi.nlm.nih.gov/27213267/">opioid</a> pain medications, and invasive treatments such as spine <a href="https://pubmed.ncbi.nlm.nih.gov/19127161/">injections</a>, spine <a href="https://pubmed.ncbi.nlm.nih.gov/12709856/">surgery</a> and battery-powered electrical stimulation of spinal nerves.</p> <h2>So how should low back pain be treated?</h2> <p>A complex range of factors <a href="https://pubmed.ncbi.nlm.nih.gov/29112007/">typically contribute</a> to a person developing chronic low back pain. This includes over-protecting the back by avoiding movement and activity, the belief that pain is related to damage, and negative emotions such as pain-related fear and anxiety.</p> <p>Addressing these factors in an individualised way is <a href="https://pubmed.ncbi.nlm.nih.gov/29573871/">now considered</a> best practice.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/15936976/">Best practice care</a> also needs to be person-centred. People suffering from chronic low back pain want to be heard and validated. They <a href="https://pubmed.ncbi.nlm.nih.gov/35384928/">want</a> to understand why they have pain in simple language.</p> <p>They want care that considers their preferences and gives a safe and affordable pathway to pain relief, restoring function and getting back to their usual physical, social and work-related activities.</p> <p>An example of this type of care is cognitive functional therapy.</p> <h2>What is cognitive functional therapy?</h2> <p><a href="https://pubmed.ncbi.nlm.nih.gov/29669082/">Cognitive functional therapy</a> is about putting the person in the drivers’ seat of their back care, while the clinician takes the time to guide them to develop the skills needed to do this. It’s led by physiotherapists and can be used once serious causes of back pain have been ruled out.</p> <p>The therapy helps the person understand the unique contributing factors related to their condition, and that pain is usually not an accurate sign of damage. It guides patients to relearn how to move and build confidence in their back, without over-protecting it.</p> <p>It also addresses other factors such as sleep, relaxation, work restrictions and engaging in physical activity based on the <a href="https://www.restorebackpain.com/patient-journey">person’s preferences</a>.</p> <p>Cognitive functional therapy usually involves longer physiotherapy sessions than usual (60 minutes initially and 30-45 minute follow-ups) with up to seven to eight sessions over three months and booster sessions when required.</p> <h2>What’s the evidence for this type of therapy?</h2> <p>Our recent clinical trial of cognitive functional therapy, published in <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(23)00441-5/fulltext">The Lancet</a>, included 492 people with chronic low back pain. The participants had pain for an average of four years and had tried many other treatments.</p> <p>We first trained 18 physiotherapists to competently deliver cognitive functional therapy across Perth and Sydney over six months. We compared the therapy to the patient’s “usual care”.</p> <p>We found large and sustained improvements in function and reductions in pain intensity levels for people who underwent the therapy, compared with those receiving usual care.</p> <p>The effects remained at 12 months, which is unusual in low back pain trials. The effects of most recommended interventions such as exercise or psychological therapies are <a href="https://pubmed.ncbi.nlm.nih.gov/34580864/">modest in size</a> and tend to be of <a href="https://pubmed.ncbi.nlm.nih.gov/32794606/">short duration</a>.</p> <p>People who underwent cognitive functional therapy were also more confident, less fearful and had a more positive mindset about their back pain at 12 months. They also liked it, with 80% of participants satisfied or highly satisfied with the treatment, compared with 19% in the usual care group.</p> <p>The treatment was as safe as usual care and was also cost-effective. It saved more than A$5,000 per person over a year, largely due to increased participation at work.</p> <h2>What does this mean for you?</h2> <p>This trial shows there are safe, relatively cheap and effective treatments options for people living with chronic pain, even if you’ve tried other treatments without success.</p> <p><a href="https://www.restorebackpain.com/cft-clinicians">Access to clinicians</a> trained in cognitive functional therapy is currently limited but will expand as training is scaled up.</p> <p>The costs depend on how many sessions you have. Our studies show some people improve a lot within two to three sessions, but most people had seven to eight sessions, which would cost around A$1,000 (aside from any Medicare or private health insurance rebates). <img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/207009/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/peter-osullivan-48973">Peter O'Sullivan</a>, Professor of Musculoskeletal Physiotherapy, <a href="https://theconversation.com/institutions/curtin-university-873">Curtin University</a>; <a href="https://theconversation.com/profiles/jp-caneiro-1463060">JP Caneiro</a>, Research Fellow in physiotherapy, <a href="https://theconversation.com/institutions/curtin-university-873">Curtin University</a>; <a href="https://theconversation.com/profiles/mark-hancock-1463059">Mark Hancock</a>, Professor of Physiotherapy, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a>, and <a href="https://theconversation.com/profiles/peter-kent-1433302">Peter Kent</a>, Adjunct Associate Professor of Physiotherapy, <a href="https://theconversation.com/institutions/curtin-university-873">Curtin University</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How the brain stops us learning from our mistakes – and what to do about it

<p>You learn from your mistakes. At least, most of us have been told so. But science shows that we often fail to learn from past errors. Instead, we are likely to keep repeating the same mistakes.</p> <p>What do I mean by mistakes here? I think we would all agree that we quickly learn that if we put our hand on a hot stove, for instance, we get burned, and so are unlikely to repeat this mistake again. That’s because our brains create a threat-response to the physically painful stimuli based on past experiences. But when it comes to thinking, behavioural patterns and decision making, we often repeat mistakes – such as being late for appointments, leaving tasks until the last moment or judging people based on first impressions.</p> <p>The reason can be found in the way our brain processes information and creates templates that we refer to again and again. These templates are essentially shortcuts, which help us make decisions in the real world. But these shortcuts, known as heuristics, can also make us repeat our errors.</p> <p>As I discuss in my book <a href="https://www.drpragyaagarwal.co.uk/sway-press">Sway: Unravelling Unconscious Bias</a>, humans are not naturally rational, even though we would like to believe that we are. Information overload is exhausting and confusing, so we filter out the noise.</p> <p>We only see parts of the world. We tend to notice things that are repeating, whether there are any patterns or not, and we tend to preserve memory by generalising and resorting to type. We also draw conclusions from sparse data and use cognitive shortcuts to create a version of reality that we implicitly want to believe in. This creates a reduced stream of incoming information, which helps us connect dots and fill in gaps with stuff we already know.</p> <p>Ultimately, our brains are lazy and it takes a lot of cognitive effort to change the script and these shortcuts that we have already built up. And so we are more likely to fall back on the same patterns of behaviours and actions, even when we are conscious of repeating our mistakes. This is called confirmation bias – our tendency to confirm what we already believe in, rather than shift our mindset to incorporate new information and ideas.</p> <p>We also often deploy “<a href="https://theconversation.com/is-it-rational-to-trust-your-gut-feelings-a-neuroscientist-explains-95086">gut instinct</a>” - an automatic, subconscious type of thinking that draws on our accumulation of past experiences while making judgements and decisions in new situations.</p> <p>Sometimes we stick with certain behaviour patterns, and repeat our mistakes because of an “<a href="https://www.sciencedirect.com/science/article/pii/S0014292121002786">ego effect</a>” that compels us to stick with our existing beliefs. We are likely to selectively choose the information structures and feedback that help us protect our egos.</p> <p>One experiment found that when people were reminded of their successes of the past, they were more likely to <a href="https://www.sciencedirect.com/science/article/abs/pii/S1057740815000728">repeat those successful behaviours</a>. But when they were conscious of or actively made aware of their failures from the past, they were less likely to overturn the pattern of behaviour that led to failure. So people were in fact still likely to repeat that behaviour.</p> <p>That’s because, when we think of our past failures, we are likely to feel down. And in those moments, we are more likely to indulge in behaviour that makes us feel comfortable and familiar. Even when we think carefully and slowly, our brains have a bias towards the information and templates we had used in the past, regardless of whether these resulted in errors. This is called the <a href="https://www.psychologytoday.com/gb/blog/mind-my-money/200807/familiarity-bias-part-i-what-is-it">familiarity bias</a>.</p> <p>We can learn from mistakes though. In one experiment, monkeys and humans had to watch noisy, moving dots on a screen and judge their net direction of movement. The researchers found that both slowed down after an error. The larger the error, the longer the post-error slowing, showing more information was being accumulated. However, the quality of this information <a href="https://www.eurekalert.org/news-releases/809286">was low</a>. Our cognitive shortcuts can force us to override any new information that could help prevent repeating mistakes.</p> <p>In fact, if we make mistakes while performing a certain task, “frequency bias” makes us likely to repeat them whenever we do the task again. Simplistically speaking, our brains start assuming that the errors we’ve previously made are the correct way to perform a task – creating a habitual <a href="https://link.springer.com/article/10.3758/pbr.15.1.156">“mistake pathway”</a>. So the more we repeat the same tasks, the more likely we are to traverse the mistake pathway, until it becomes so deeply embedded that it becomes a set of permanent cognitive shortcuts in our brains.</p> <p><strong>Cognitive control</strong></p> <p>It sounds bleak, so what can be done?</p> <p>We do have a mental ability that can override heuristic shortcuts, known as “cognitive control”. And there are some <a href="https://www.cell.com/neuron/fulltext/S0896-6273(21)00075-1">recent studies in neuroscience with mice</a> that are giving us a better idea of what parts of our brains are involved in that.</p> <p>Researchers have also <a href="https://www.cell.com/neuron/fulltext/S0896-6273(18)31007-9">identified two brain regions</a> with “self-error monitoring neurons” – brain cells which monitor errors. These areas are in the frontal cortex and appear to be part of a sequence of processing steps – from refocusing to learning from our mistakes.</p> <p>Researchers are exploring whether a better understanding of this could help with development of better treatments and support for Alzheimer’s, for example, as preserved cognitive control is crucial for <a href="https://www.frontiersin.org/articles/10.3389/fnagi.2020.00198/full">wellbeing in later life</a>.</p> <p>But even if we don’t have a perfect understanding of the brain processes involved in cognitive control and self-correction, there are simpler things we can do.</p> <p>One is to become more comfortable with making mistakes. We might think that this is the wrong attitude towards failures, but it is in fact a more positive way forward. Our society denigrates failures and mistakes, and consequently we are likely to feel shame for our mistakes, and try and hide them.</p> <p>The more guilty and ashamed we feel, and the more we try and hide our mistakes from others, the more likely we are to repeat them. When we not feeling so down about ourselves, we are more likely to be better at taking on new information that can help us correct our mistakes.</p> <p>It can also be a good idea to take a break from performing a task that we want to learn how to do better. Acknowledging our failures and pausing to consider them can help us reduce frequency bias, which will make us less likely to repeat our mistakes and reinforce the mistake pathways.</p> <p><em>Image credit: Shutterstock</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/how-the-brain-stops-us-learning-from-our-mistakes-and-what-to-do-about-it-203436" target="_blank" rel="noopener">The Conversation</a>. </em></p>

"I sobbed in the paddock”: Sam Armytage's home life challenges

<p>Sam Armytage has revealed why she "sobbed in a paddock" recently, as she shared the trials and tribulations of life in the country. </p> <p>After the former <em>Sunrise</em> presenter quit the Channel 7 breakfast show, she moved to the NSW Southern Highlands with her horse-breeding farmer husband, Richard Lavender.</p> <p>The quaint town of Berrima boasts a different way of life to bustling Sydney and comes with its own unique hurdles, as Armytage told <a href="https://www.dailytelegraph.com.au/entertainment/celebrity/sam-armytage-reveals-why-she-sobbed-in-a-paddock-recently/news-story/21e80ca290d80db23f808e7f4c8453b5" target="_blank" rel="noopener"><em>The Daily Telegraph</em></a>. </p> <p>“We had to put down one of our most promising and sweet-natured racehorses last week, after he broke his leg in an accident. I sobbed in the paddock,” Armytage told the publication.</p> <p>Elsewhere in the interview, she also revealed the advice she’d give her 10-year-old self.</p> <p>“That the people who are mean to you throughout life are usually jealous of who you are – and what you have,” Armytage said.</p> <p>Just weeks ago, Armytage was announced as the <a href="https://oversixty.com.au/entertainment/tv/sam-armytage-s-major-new-role" target="_blank" rel="noopener">new host</a> of <em>Farmer Wants a Wife</em>: a role previously held by Natalie Gruzlewski, who has hosted the series on-and-off ever since its debut in 2007.</p> <p>Her return to hosting duties comes after Armytage admitted she would never return to <em>Sunrise</em>. </p> <p>“I’d never go back. You don’t go backwards in life. You’ve got to keep going forward,” she said.</p> <p>She went on to say she senses “fear” in the media landscape these days, saying, “When I do listen to radio and TV, no-one’s actually saying what they mean.”</p> <p>“Everybody’s walking this tightrope because they fear they’ll say the wrong thing and the mob will descend on them, and that’s not journalism, and it’s not what I was paid to do back in the old days."</p> <p><em>Image credits: Instagram</em></p>

"I'm not afraid to challenge myself": J-Lo's secret to staying physically and mentally fit

<p>Jennifer Lopez has shared an insight into her gruelling workout routine, revealing it is the best thing for both her physical and mental wellness. </p> <p>The 53-year-old singer and actress told US Weekly how important moving her body is to help keep a positive mental attitude. </p> <p>"It's no secret that fitness is a very important part of my life... I think there's a positive correlation between exercise and mental health," she said. </p> <p>J-Lo's claims have long been backed up by healthcare professionals, with the MentalHealth.org website reading, "Research shows that people who exercise regularly have better mental health and emotional wellbeing, and lower rates of mental illness."</p> <p>"Taking up exercise seems to reduce the risk of developing mental illness... and seems to help in treating some mental health conditions, like depression and anxiety."</p> <p>Lopez went on to say, "When you find a good balance through determination and focus, we're naturally pushing to be the best version of ourselves."</p> <p>She usually begins her workouts "first thing in the morning", which usually means rolling out of bed before 5am. </p> <p>J-Lo regularly mixes up her workouts, explaining, "I'm always evolving and looking for things that keep me excited and motivated."</p> <p>"I'm not afraid to challenge myself, so I'm open to pushing myself, which is what I'm doing right now as I rehearse for my new album, [This Is Me… Now], coming out this summer."</p> <p>Even Jennifer's trainer Tracy Anderson said the pop star goes above and beyond for her health and fitness, pushing herself for maximum results. </p> <p>'"She shows up no matter what, she takes the time seriously, she knows her body, she wants to be herself," Anderson has said. </p> <p>"She knows that putting in the hard work to get her workout in is part of it."</p> <p><em>Image credits: Getty Images</em></p>

3 ways your brain changes with ageing

<p dir="ltr">Your entire body changes when you age, including your brain, which is responsible for everything. Regardless of your physical or neurological health, there is such a thing as “cognitive ageing.” It happens to the best of us!</p> <p dir="ltr">So, what are these changes? </p> <p dir="ltr" role="presentation"><strong>1. Processing speed</strong></p> <p dir="ltr">This refers to how quickly the brain can process information and provide a response. Processing speed affects almost every function in the brain, and it’s measured by how quickly you can manage a mental task. </p> <p dir="ltr">How it changes with ageing: </p> <ul> <li dir="ltr" aria-level="1"> <p dir="ltr" role="presentation">It decreases over time.</p> </li> <li dir="ltr" aria-level="1"> <p dir="ltr" role="presentation">The decrease starts in early adulthood, so by the time you reach your 70s and 80s, your processing speed is significantly down compared to the speed you once had in your 20s. </p> </li> </ul> <p dir="ltr"><strong>2. Memory</strong></p> <p dir="ltr">Memory is complex, and there’s different kinds of memory, but these are the functions that you’ll notice changes in as you age:</p> <ul> <li dir="ltr" aria-level="1"> <p dir="ltr" role="presentation">Working memory, the ability to hold information and manipulate it mentally, declines </p> </li> <li dir="ltr" aria-level="1"> <p dir="ltr" role="presentation">Episodic memory, the ability to remember personally experienced events at a certain plane or time, declines </p> </li> <li dir="ltr" aria-level="1"> <p dir="ltr" role="presentation">Prospective memory, the ability to remember to do things in the future, declines</p> </li> </ul> <p dir="ltr"><strong>3. Attention</strong></p> <p dir="ltr">The ability to concentrate and focus on something specific so that information can be mentally processed changes. </p> <ul> <li dir="ltr" aria-level="1"> <p dir="ltr" role="presentation">Selective attention, the ability to focus on something specific despite distractions or irrelevant stimuli, declines</p> </li> <li dir="ltr" aria-level="1"> <p dir="ltr" role="presentation">Divided attention, also known as “multi-tasking”, declines</p> </li> <li dir="ltr" aria-level="1"> <p dir="ltr" role="presentation">Sustained attention, the ability to remain concentrated on one task for an extended period of time, declines</p> </li> </ul> <p dir="ltr"><strong>Can anything be done?</strong></p> <p dir="ltr">Unfortunately, there is no way to combat cognitive ageing, but there are things you can do to keep your brain healthy, which in turn will help keep you sharp.</p> <ul> <li dir="ltr" aria-level="1"> <p dir="ltr" role="presentation">Adequate sleep</p> </li> <li dir="ltr" aria-level="1"> <p dir="ltr" role="presentation">Proper nutrition</p> </li> <li dir="ltr" aria-level="1"> <p dir="ltr" role="presentation">Stimulate your brain with crosswords, sudoku or brain training apps </p> </li> <li dir="ltr" aria-level="1"> <p dir="ltr" role="presentation">Speak to people every day</p> </li> <li dir="ltr" aria-level="1"> <p dir="ltr" role="presentation">Read more</p> </li> </ul> <p dir="ltr">The longer you wait to help keep your brain healthy, the harder it becomes for your brain to remember things. </p> <p dir="ltr"><em>Image credit: Shutterstock</em></p> <p> </p>

The Klim Swim: Michael's next big challenge after devastating diagnosis

<p>Australian swimming icon Michael Klim has refused to let his autoimmune disorder hold him back from the things he loves, returning to the gym to rebuild his body after his 2019 diagnosis. </p> <p>The 45-year-old world record holder has chronic inflammatory demyelinating polyneuropathy (CIDP) – a rare auto-immune disorder that targets the arms and legs, and the body’s nerves. And while things haven’t necessarily been easy for the swimmer, Michael’s positive attitude has assured supporters that big things are still to come for him. </p> <p>“It has obviously been a challenging three or four years since the diagnosis,” he told the <em>Sunrise </em>team, “but I think I have accepted what I’ve got and I’m trying to make the most of it.</p> <p>“I have a great support crew, obviously my family, my partner Michelle, and it does take more than one person to get through this, and it has been pretty challenging but I am upbeat and pretty positive.</p> <p>A lot of people have come up to me and said ‘oh, you’re an Olympian, you’re mentally super tough’ but for me, the physical change has been so huge, it is hard to fathom,” Klim said.</p> <p>“I can’t even stand on one leg at the moment, so it’s really basic ... understanding that, that is my norm, and I have to slowly build up from that.</p> <p>“I am focusing on the things I can do rather than the things I can’t.”</p> <p>And the item at the top of his ‘can do, will do’ list? Encouraging Australians to dive into their local pools (or favourite swimming spot) to take on the <a href="https://www.klimswimchallenge.com.au/homepage" target="_blank" rel="noopener">Brainwave Klim Swimming Challenge</a> with him. </p> <p>Michael has been hard at work training in preparation for the event that asks Australians to swim as much as they can during the month of March to raise funds for children with neurological conditions - like his own - and their families. Michael himself hopes to raise $300,000 for the foundation through his swim school franchise Klim Swim. </p> <p>“No matter how far you choose to swim,” he wrote on Instagram about the challenge, “every stroke counts!” </p> <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/reel/Cobnb5-jo4k/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/reel/Cobnb5-jo4k/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by Brainwave Australia (@brainwaveaus)</a></p> </div> </blockquote> <p>“For the month of March, we are encouraging everyone to have a swim.

Priscilla Presley challenges Lisa Marie’s will

<p>Priscilla Presley has taken her late daughter’s trust to court mere weeks after Lisa Marie’s death on January 12. </p> <p>Priscilla allegedly discovered a document from 2016 that concerns an amendment to the trust. The actor and business woman reportedly filed documents that challenge this “purported 2016 amendment” to Lisa Marie’s will, and has asked that it be deemed “invalid”.</p> <p>Said amendment ousted Priscilla as trustee, instead naming Lisa Marie’s eldest daughter, Riley Keough, and her late son, Benjamin Keough, as co-trustees. However, Benjamin Keough passed away in 2020, leaving Riley as the sole trustee to their late mother’s estate. Priscilla claims that she and Barry Siegel, Lisa Marie's former business manager, were appointed co-trustees in 1993.</p> <p>Lisa Marie was the sole heir to Elvis Presley’s fortune after his death in 1977. The Graceland mansion is reported to be worth more than $100m USD (approximately $141m AUD).</p> <p>Priscilla questions the “authenticity and validity” of the amendment, and alleges that her daughter’s signature “appears inconsistent with her usual and customary signature” on the document from 2016, and even argues that Lisa Marie’s name had been spelled incorrectly. On top of this, Priscilla claims that the document wasn’t notarised.</p> <p>According to court documents, “Lisa Marie Presley appointed her mother, Petitioner, and her former business manager, Barry Siegel, as co-Trustees effective as of the date of the 2010 restatement.</p> <p>“The 2010 restatement further provides that Petitioner and Barry Siegel shall continue to serve as co-Trustees upon Lisa Marie Presley’s subsequent incapacity and/or death.</p> <p>“The Purported 2016 Amendment removed and replaced Petitioner and Barry as both current and successor Trustees of the Trust with Lisa Marie Presley as the current Trustee and naming Lisa Marie Presley’s daughter, Riley Keough, and son, Benjamin Keough, as successor co-Trustees of the Trust upon Lisa Marie Presley’s incapacity and/or 10 death.”</p> <p>Priscilla’s legal move comes less than one week after a memorial service for Lisa Marie at the Graceland estate in Memphis, Tennessee. </p> <p><em>Images: Getty</em></p> <p> </p>

Mentally challenging work might actually be really good for you

<p>Mentally challenging work, despite feeling draining at the time, could help to better protect people from memory and cognitive decline in old age, according to a new study. Published in Neurology, the research suggests that workers, who are required to speak more, develop strategies, manage others, and resolve conflict may be better off than their colleagues who do less of the same activities.</p> <p>Author study, Francisca Then, from Germany’s University of Leipzig explains, “Our study is important because it suggests that the type of work you do throughout your career may have even more significance on your brain health than your education does. Education is a well-known factor that influences dementia risk.”</p> <p>It has been shown in the past that, just like education, staying mentally active with puzzles and games, as well as maintaining a healthy social life may delay dementia’s onset, and reduce mental decline.</p> <p>The study assessed 1,054 individuals aged 75 or older from the Leipzig Longitudinal Study of the Aged, which is a representative population-based cohort study. Each of the study’s participants underwent cognitive testing every 18 months to evaluate their memory and thinking abilities for eight years in total. They were also asked to discuss their work history, categorising the types of tasks they did into one of three groups:</p> <ul> <li>Executive tasks, like conflict resolution, or strategy development</li> <li>Verbal tasks, such as interpreting and evaluating information</li> <li>Fluid tasks, like data analysis</li> </ul> <p>The research showed that participants who had performed tasks at the highest level of all three categories during their careers scored highest on the memory and thinking evaluation. They were also found to have the slowest rate of cognitive decline over the eight-year study.</p> <p>The study’s authors concluded that, “The results suggest that a professional life enriched with work tasks stimulating verbal intelligence and executive functions may help to sustain a good cognitive functioning in old age.”</p> <p><em>Source: <span style="text-decoration: underline;"><strong><a href="http://www.medicalnewstoday.com/articles/293325.php" target="_blank" rel="noopener">Medical News Today</a></strong></span></em></p> <p><em>Image: Getty</em></p>

Long COVID: How lost connections between nerve cells in the brain may explain cognitive symptoms

<p>For a portion of people who get COVID, symptoms continue for <a href="https://www.ons.gov.uk/peoplepopulationandcommunity/healthandsocialcare/conditionsanddiseases/bulletins/prevalenceofongoingsymptomsfollowingcoronaviruscovid19infectionintheuk/6october2022" target="_blank" rel="noopener">months or even years</a> after the initial infection. This is commonly referred to as “long COVID”.</p> <p>Some people with long COVID complain of “<a href="https://theconversation.com/what-is-and-what-isnt-brain-fog-190537" target="_blank" rel="noopener">brain fog</a>”, which includes a wide variety of cognitive symptoms affecting memory, concentration, sleep and speech. There’s also growing concern about findings that people who have had COVID are at <a href="https://www.thelancet.com/journals/lanpsy/article/PIIS2215-0366(22)00260-7/fulltext" target="_blank" rel="noopener">increased risk</a> of developing brain disorders, such as dementia.</p> <p>Scientists are working to understand how exactly a COVID infection affects the human brain. But this is difficult to study, because we can’t experiment on living people’s brains. One way around this is to create <a href="https://www.nature.com/articles/s41578-021-00279-y" target="_blank" rel="noopener">organoids</a>, which are miniature organs grown from stem cells.</p> <p>In a <a href="https://www.nature.com/articles/s41380-022-01786-2.pdf" target="_blank" rel="noopener">recent study</a>, we created brain organoids a little bigger than a pinhead and infected them with SARS-CoV-2, the virus that causes COVID-19.</p> <p>In these organoids, we found that an excessive number of synapses (the connections between brain cells) were eliminated – more than you would expect to see in a normal brain.</p> <p>Synapses are important because they allow neurons to communicate with each other. Still, the elimination of a certain amount of inactive synapses is part of normal brain function. The brain essentially gets rid of old connections when they’re no longer needed, and makes way for new connections, allowing for more efficient functioning.</p> <p>One of the crucial functions of the brain’s immune cells, or <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5768411/" target="_blank" rel="noopener">microglia</a>, is to prune these inactive synapses.</p> <p>The exaggerated elimination of synapses we saw in the COVID-infected models could explain why some people have cognitive symptoms as part of long COVID.</p> <p><strong>Parallels with neurodegenerative disorders</strong></p> <p>Interestingly, this pruning process is believed to go awry in several disorders affecting the brain. In particular, excessive elimination of synapses has recently been linked to <a href="https://www.nature.com/articles/s41593-018-0334-7" target="_blank" rel="noopener">neurodevelopmental disorders</a> such as <a href="https://www.nature.com/articles/s41593-018-0334-7" target="_blank" rel="noopener">schizophrenia</a>, as well as <a href="https://www.frontiersin.org/articles/10.3389/fncel.2019.00063/full" target="_blank" rel="noopener">neurodegenerative disorders</a> such as Alzheimer’s and Parkinson’s disease.</p> <p>By sequencing the RNA of single cells, we could study how different cell types in the organoid responded to the virus. We found that the pattern of genes turned on and off by the microglia in our COVID-infected organoids mimicked changes seen in neurodegenerative disorders.</p> <p>This may go some way in explaining the link between COVID and the risk of developing certain neurological disorders.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/491380/original/file-20221024-17-9wi5pg.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/491380/original/file-20221024-17-9wi5pg.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=338&fit=crop&dpr=1 600w, https://images.theconversation.com/files/491380/original/file-20221024-17-9wi5pg.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=338&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/491380/original/file-20221024-17-9wi5pg.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=338&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/491380/original/file-20221024-17-9wi5pg.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=425&fit=crop&dpr=1 754w, https://images.theconversation.com/files/491380/original/file-20221024-17-9wi5pg.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=425&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/491380/original/file-20221024-17-9wi5pg.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=425&fit=crop&dpr=3 2262w" alt="" /><figcaption><span class="caption">A brain organoid used in our study.

High score: Video game play linked to better cognitive performance

<p>Children playing video games for more than three hours a day score better on cognitive performance compared to non-gamers.</p> <p>A study involving more than 1,800 children aged nine and ten by researchers at the University of Vermont in the United States, is believed to be the largest investigation looking at the association between <a href="https://cosmosmagazine.com/people/good-games/" target="_blank" rel="noreferrer noopener">video games</a>, cognition and brain function. </p> <p>The researchers found children who played more than 21 hours of video games per week recorded better scores for <a href="https://cosmosmagazine.com/technology/can-games-tell-if-you-are-impulsive/" target="_blank" rel="noreferrer noopener">response inhibition</a> and working memory than those who never played. The article is <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2797596?utm_source=For_The_Media&utm_medium=referral&utm_campaign=ftm_links&utm_term=102422" target="_blank" rel="noreferrer noopener">published</a> in JAMA Network Open.</p> <p>Lead author Dr Bader Chaarani told Cosmos, “it makes sense that if you consider the brain is like a muscle, the more you train it, the better it performs.” </p> <p>Impulse control is considered important as it is linked to substance use in adolescence, while working memory is connected to IQ and language processing, Chaarani says.</p> <p>In the study, the children performed two tasks inside an MRI scanner. The first was a ‘stop signal task’ measuring impulse control. The task required children to press a button when arrows pointed left or right, but not press anything when the arrows point up. The second, a working memory task showed children pictures of faces and tested their recall.</p> <p>Children were also tested outside the scanner using oral and verbal tasks.</p> <p>In contrast to the findings of other research, the study did not find any significant difference between gamers and non-gamers in terms of mental health or behaviour. </p> <div class="newsletter-box"> <div id="wpcf7-f6-p220302-o1" class="wpcf7" dir="ltr" lang="en-US" role="form"> <form class="wpcf7-form mailchimp-ext-0.5.62 spai-bg-prepared init" action="/technology/high-score-video-game-play-linked-to-better-cognitive-performance/#wpcf7-f6-p220302-o1" method="post" novalidate="novalidate" data-status="init"> <p style="display: none !important;"><span class="wpcf7-form-control-wrap referer-page"><input class="wpcf7-form-control wpcf7-text referer-page" name="referer-page" type="hidden" value="https://cosmosmagazine.com/technology/" data-value="https://cosmosmagazine.com/technology/" aria-invalid="false" /></span></p> <p></form> </div> </div> <p>Chaarani says, “many parents today are concerned about the effects of video games on their children’s health and development, and as these games continue to proliferate among young people, it is crucial that we better understand both the positive and negative impact that such games may have.”</p> <p>In Australia, 78% of children and teenagers play video games, averaging 106 minutes per day, according to <a href="https://igea.net/wp-content/uploads/2021/10/DA22-Report-FINAL-19-10-21.pdf" target="_blank" rel="noreferrer noopener">research commissioned</a> by the Interactive Games and Entertainment Association.</p> <p>In the University of Vermont study, non-video gamers (who spent zero hours a week playing games) and gamers (who played more than 21 hours a week) were recruited from a mix of 21 public, private and charter schools across the United States.</p> <p>The two groups did not differ in terms of characteristics such as age, BMI or IQ. However, the gamers group had a higher share of boys, and lower parental income on average.</p> <p>The research forms part of the <a href="https://abcdstudy.org" target="_blank" rel="noreferrer noopener">Adolescent Brain Cognitive Development Study</a>, the largest long-term study of brain development and child health in the United States. This allows children to be tracked over time into early adulthood to see if changes in video gaming behaviour are linked to changes in cognitive skills, brain activity, behaviour, and mental health.</p> <p>While the results showed an association between playing video games and higher cognitive performance, the paper notes it does not evidence for causality. This will be the focus of further research, given the Adolescent Brain Cognitive Development Study follows children every two years.</p> <p>Chaarani says they also plan to look at the effect of video game genre in future work. The current study did not differentiate by the type of video games children played, whether puzzle games, action adventure, sports, simulation or shooters; or single versus multi-player games. </p> <p>“There are some smaller studies reporting that different types of games may engage different areas in the brain, different functions of the brain… but because of the sample size we cannot trust them enough,” he says.</p> <p>“For the nine and ten years old, we’ve been looking at surveys done internationally. So, these kids tend to play more fast-paced games like action, adventure and shooters that give you immediate reward rather than slow paced games.”</p> <p></p> <p><img id="cosmos-post-tracker" style="opacity: 0; height: 1px!important; width: 1px!important; border: 0!important; position: absolute!important; z-index: -1!important;" src="https://syndication.cosmosmagazine.com/?id=220302&title=High+score%3A+Video+game+play+linked+to+better+cognitive+performance" width="1" height="1" /></p> <p></p> <div id="contributors"> <p><em><a href="https://cosmosmagazine.com/technology/high-score-video-game-play-linked-to-better-cognitive-performance/" target="_blank" rel="noopener">This article</a> was originally published on Cosmos Magazine and was written by Petra Stock.</em></p> <p><em>Image: Getty Images</em></p> </div>

10 great tips for surviving challenging moments in relationships

<p>While it can be tempting to turn tail and run when the going gets tough, studies have shown time and time again that taking a deep breath and trying to work through your issues gives you the best chance of salvaging and maintaining your relationship. Here are our top 10 tips for working it through when times get tough.</p> <ol> <li>Remove your emotions from the equation – It may be tricky but an emotionally charged conversation never ends well. If you’re feeling furious, try and put a pause on things till you’ve calmed down.</li> <li>Forget right or wrong – Delegating parties as “right” or “wrong” is a great way of ensuring arguments remain unresolved. It’s important to bot take responsibility for your actions.</li> <li>Walk the high road – Work out what works best for you as an individual couple. It’s all about equality and contentment in your own circumstances.</li> <li>Be humble, always – We all make mistakes. Reminding or gloating over the ones your partner makes never ends well.</li> <li>Agree to disagree – A healthy relationship will often have topics where each party holds a differing view to the other. This is normal and can be a great vehicle for discussion. It’s important though that you both value and respect the others opinion, even if it differs from your own.</li> <li>Be mindful of others – Difficult conversations are best held in private, away from those whose input may be unhelpful.</li> <li>Consider all your options – If you’re facing an issue as a couple, remember to consider all your options for a resolution. This often requires some brainstorming and partnering together to find a positive solution.</li> <li>Don’t rush into a decision – If you’re struggling to reconcile what you think with certain actions, take a step back and sleep on it.</li> <li>Stay optimistic – Approaching a discussion positively can make the process much easier.</li> <li>Review and consolidate – When you reach a conclusion, reaffirm it a few times before agreeing to move on.</li> </ol> <p><em>Image: Getty</em></p>

Your dog can get dementia - here’s how to prevent it

<p dir="ltr">Just like us, dogs can experience cognitive decline as they age. They can also risk developing a neurodegenerative condition called Canine Cognitive Dysfunction (CCD), a condition similar to Alzhheimer’s Disease.</p> <p dir="ltr">Like Alzheimer’s, symptoms dogs with CCD can experience include a loss of spatial awareness, memory deficiencies, disrupted sleep, and altered social interactions.</p> <p dir="ltr">Both CCD and Alzheimer’s also share symptoms found in the brain itself, including <a href="https://oversixty.com.au/health/mind/alzheimer-s-marker-found-in-the-brain" target="_blank" rel="noopener">the buildup of fragments of a protein called beta-amyloid</a> in between nerve cells.</p> <p dir="ltr">According to a new study published in the journal <em><a href="https://doi.org/10.1038/s41598-022-15837-9" target="_blank" rel="noopener">Scientific Reports</a></em>, the risk of developing CCD increases by 68 percent each year after dogs turn 10.</p> <p dir="ltr">The team studied a whopping 15,019 dogs that took part in a longitudinal study called the Dog Ageing Project. Between 2019 and 2020, the owners of participating pets completed two surveys about the health status and physical activity of their dogs. They also completed the Canine Social and Learned Behaviour survey, which tested for symptoms of CCD such as dogs failing to recognise familiar people.</p> <p dir="ltr">But, they also found that older pooches that were very active had a much smaller risk of developing the condition in comparison to less active dogs of the same breed and health - with the more sedentary dogs having a 6.47 times higher risk of having CCD.</p> <p dir="ltr">They stress that their study doesn’t show that a lack of physical activity causes CCD, and are calling for more research to determine whether CCD is caused by less physical activity or if the inactivity is caused by CCD.</p> <p dir="ltr">Because of the similarities between CCD and Alzheimer’s disease, the team argue that means that researching CCD could have implications for our understanding and treatment of Alzheimer’s, and vice versa.</p> <p dir="ltr">For example, the association between physical activity and lower risks of CCD come after numerous studies showing this relationship in rodents <a href="https://oversixty.com.au/health/mind/the-surprising-reason-exercise-improves-symptoms-of-alzheimer-s" target="_blank" rel="noopener">and in humans</a>.</p> <p dir="ltr">“These observations may reflect a variety of biologic mechanisms, including a reduction of pro-inflammatory cytokines in the brain that otherwise contribute to neural damage and death, and an increase in neural plasticity,” they write of the studies with rodents and people, adding that these mechanisms might also explain the link between physical activity and CCD risk.</p> <p dir="ltr">“Given increasing evidence of the parallels between canine and human cognitive disease, accurate CCD diagnosis in dogs may provide researchers with more suitable animal models in which to study ageing in human populations.”</p> <p><span id="docs-internal-guid-91437cc1-7fff-5a43-0a9a-bca582c47473"></span></p> <p dir="ltr"><em>Image: Getty Images</em></p>

The Block contestants deny cheating to win challenge

<p>Another scandal could well and truly be unfolding on this year’s season of the popular home-reno show The Block.</p> <p>Following the infamous cheating scandal that dominated the last season (much to ratings advantage) Tuesday's episode has suggested something just as juicy could be brewing behind the scenes following controversial couple Sharon and Ankara's win in the latest challenge.</p> <p>The couple were spotted using a clever tactic - pulling out their phones to Google the answers.</p> <p>In scenes aired on Tuesday night, all five teams headed off-site to Levantine Hill winery to take part in a unique challenge, where the task was replicating the taste of a premium wine blend: a 2015 Samantha’s Paddock Mélange Traditionnel.</p> <p>They had to taste and mix several wines together to make their own bottle, the closest attempt would win $50,000 of wine to take back to The Block. The win would increase the value of their home.</p> <p>As the rest of the teams muddled through various blends and taste tests, Sharon and Ankur appeared to simply just Google search the ingredients and wine notes, by-passing the trickier elements of the task.</p> <p>After glancing around nervously, Ankur announced: “Cool. I know what it is, I know the percentages … We’ve got Cab Sav, Merlot, Malbec, Cabernet, Petit Verdot.”</p> <p>Defending the decision, the couple have declared they hadn’t broken any rules during the challenge, stating: “There are absolutely no rules that we cannot use our phones or search the net/google anything."</p> <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/p/Ch4VXEQLU4V/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/p/Ch4VXEQLU4V/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by Ankur and Sharon (@ankurandsharon)</a></p> </div> </blockquote> <p>“This part of the challenge required us to create a 2022 blend of the wine, which doesn’t exist.

Dannii Minogue reveals the challenges she faced while filming Young Talent Time

<p>Dannii Minogue has shared the challenges she faced while appearing on <em>Young Talent Time</em> as a child. </p> <p>Speaking with Kyle and Jackie O, the 50-year-old entertainer said she felt immense pressure to balance her school work and time spent at rehearsals.</p> <p>"I was the biggest nerd when I was on <em>Young Talent Time</em>. I was in the library at lunch doing my homework so I could go straight to rehearsals after school," she said during an interview on Tuesday. </p> <p>"I was obsessed with getting good grades and if I didn't finish [my homework] at lunch time I'd have to do it when I got home and I wouldn't sleep till 11pm."</p> <p>Dannii starred in <em>Young Talent Time</em> from 1982 to 1988, as well as <em>Young Talent Time: The Next Generation</em> which was launched in America.</p> <p>Following her six year run on the show, she went on to play the role of Emma Jackson in <em>Home & Away</em> in 1989. </p> <p>She stayed with the Aussie soap for a year before launching her music career, like her famed sister Kylie Minogue, in 1990.</p> <p><em>Young Talent Time</em> featured a core group of young performers who would sing both classic songs and hits of the day while hopefuls competed in a weekly talent quest.</p> <p>The series was hosted by Johnny Young and aired from 1971 to 1988, and proved to be hugely popular after spawning no less than 15 albums and a slew of merchandise. </p> <p><em>Image credits: Seven</em></p>

Children’s stories can challenge stereotypes

<p>As book week draws near, new research shows the potential power of children’s books to challenge gendered stereotypes in science, technology, engineering and maths. Meanwhile Australian children are spoilt for choice when it comes to diverse books, keep reading below for some recommendations.</p> <p>A research team from the Netherlands, the United States and Canada found when children were read a story that countered stereotypes, for example about a girl who’s good at maths, afterwards they were less likely to hold gendered stereotypes than the control group. The paper is published in PLOS one.</p> <p>The study involved reading aloud to more than 300 North American six to eleven-year-olds, with each child randomly assigned to be read one of three different books. </p> <p>The first story was stereotype-consistent, in which a boy character performed well in maths, while a girl was shown liking and excelling in reading. The second was a counter-stereotypical case, where the story was the same but the characters’ genders were reversed. The third was a neutral story where swimming and tennis replaced the activities of maths and reading.</p> <p>After being read one of the three, the children completed a child-friendly ‘implicit association test’, which involved sorting maths words (like addition, count, math, numbers) and reading related words (like books, letters, words, read) into boy and girl categories. They also completed a ‘self-concept’ test, answering questions like ‘how much do you like maths?’</p> <p>While gendered stereotypes about STEM can be formed early, an important finding of the study was that children’s attitudes are malleable, and books which counter stereotypes can help challenge the status quo.</p> <p>The findings are significant given globally and in Australia, women and girls are under-represented in STEM fields and professions, with gendered perceptions a contributing factor, acting as a barrier to girls’ engagement. </p> <p>Jo Panckridge is a teacher-librarian and the Victorian president of the Children’s Book Council of Australia. She says diversity in all its forms is having a huge impact in the publishing world. </p> <p>For Australian books offering an antidote to traditional gendered views about STEM, Panckridge reels off a long list of titles, starting with Our Little Inventor by Sher Rill Ng. It’s about a girl who invents an air purifying device to solve pollution.</p> <p>Everyday Wonders by Natala Graetz, is brilliant for younger readers Panckridge says. The book highlights mothers who are “ordinary but powerful women – they can be doctors, they can be lawyers, they can be scientists, they can be all sorts of things”.</p> <p>Stellarphant by James Foley tells the story of a girl elephant who wants to be an astronaut but is refused by the managers at Space Command. The picture book showcases “a great example of persistence and resilience” and the love of engineering, space and mathematics, Panckridge says.</p> <p>Heroes, Rebels and Innovators by Karen Wyld celebrates the significant contributions of seven iconic Aboriginal and Torres Strait Islander people and is shortlisted for the CBCA’s Eve Pownall Award for factual books.</p> <p>Andrea Beaty’s Ada Twist, Scientist and Rosie Revere, Engineer deserve a mention, along with Alex Miles’ series Girl Geeks about a group of ten-year-olds who like to code and play video games. </p> <p>“Dreaming with eyes open…” is the theme for this year’s CBCA book week (August 20 – 26). </p> <p>Panckridge says it is both a celebration of First Nations’ storytellers, as well as more broadly “an invitation for children, and teens and young adults, to dream to venture into books, to lose yourself in books and explore the places and people and experiences that stories of this country enable us to understand and to learn from.”</p> <p><strong>This article originally appeared on <a href="https://cosmosmagazine.com/people/social-sciences/childrens-books-combat-stereotypes/" target="_blank" rel="noopener">cosmosmagazine.com</a> and was written by Petra Stock.</strong></p> <p><em>Image: Shutterstock</em></p>
