Traveller divides opinion on how early you should arrive at the airport

A plane passenger has shocked even the most organised travellers after admitting that he gets to the airport six hours before his flight departs. Self-described anxious traveller Tim Murray slammed those who have a laxed attitude to an airport arrival time, boldly stating it's their own fault if they miss their flight. “It's not my fault you're late to your flight, so if you're behind me in the security line being like: ‘I gotta get past you I'm late’ you need to manage your time better”' he declared in a short clip posted to TikTok. “I get to the airport six-and-a-half hours before my flight,” he stated, admitting his “extreme anxiety” does play a role in getting there early. “And I wanna sit here and vibe at the airport Chili's with a waitress named Debra who has the most amazing smoker's voice you've ever heard and stories that will last six-and-a-half hours,” he joked. In a comment, Tim admitted that he may have over-exaggerated the six hours, but still saying he gets to the airport several hours early. While Tim seemed smug in bragging about his early arrival, many users pointed out that there are external factors that play into people's travel plans. “People need to remember it's not always the person's fault. If my plane is late that could cause me to miss my connection, no matter how early I was. This has happened to me a few times,” one person pointed out. “Have mercy on us international flyers who need to do immigration baggage claim and run to connecting flight after our first flight was delayed,” another complained. “Dude some people are connections because their flight was late, or stuck in a long customs lines… so many other reasons than being just late,” they pointed out.

Retiring early can be bad for the brain

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/plamen-v-nikolov-1112610">Plamen V Nikolov</a>, <a href="https://theconversation.com/institutions/binghamton-university-state-university-of-new-york-2252">Binghamton University, State University of New York</a> The <a href="https://theconversation.com/us/topics/research-brief-83231">Research Brief</a> is a short take about interesting academic work. <h2>The big idea</h2> People who retire early suffer from accelerated cognitive decline and may even encounter early onset of dementia, according to a I conducted with my doctoral student <a href="https://sites.google.com/binghamton.edu/alan-adelman/home">Alan Adelman</a>. To establish that finding, we examined the effects of a rural pension program China introduced in 2009 that provided people who participated with a stable income if they stopped working after the official retirement age of 60. We found that people who participated in the program and retired within one or two years experienced a cognitive decline equivalent to a drop in general intelligence of 1.7% relative to the general population. This drop is equivalent to about three IQ points and could make it harder for someone to <a href="https://doi.org/10.1017/S0033291700008412">adhere to a medication schedule</a> or <a href="https://doi.org/10.1111/j.1475-%205890.2007.00052.x">conduct financial planning</a>. The largest negative effect was in what is called “delayed recall,” which measures a person’s ability to remember something mentioned several minutes ago. Neurological research <a href="https://doi.org/10.1001/archneur.1991.00530150046016">links problems in this area to an early onset of dementia</a>. <h2>Why it matters</h2> Cognitive decline refers to when a person has trouble remembering, learning new things, concentrating or making decisions that affect their everyday life. Although some cognitive decline appears to be an inevitable byproduct of aging, faster decline can have profound adverse consequences on one’s life. Better understanding of the causes of this has powerful financial consequences. Cognitive skills – the mental processes of gathering and processing information to solve problems, adapt to situations and learn from experiences – are crucial for decision-making. They influence an individual’s ability to process information and <a href="https://www.jstor.org/stable/1818642">are connected to higher earnings</a> and a <a href="https://www.doi.org/10.1257/jep.25.1.159">better quality of life</a>. Retiring early and working less or not at all can generate large benefits, such as reduced stress, better diets and more sleep. But as we found, it also has unintended adverse effects, like fewer social activities and less time spent challenging the mind, that far outweighed the positives. While retirement schemes like the 401(k) and similar programs in other countries <a href="https://www.doi.org/10.1023/B:PUCH.0000035859.20258.e0">are typically introduced to ensure the welfare of aging adults</a>, our research suggests they need to be designed carefully to avoid unintended and significant adverse consequences. When people consider retirement, they should weigh the benefits with the significant downsides of a sudden lack of mental activity. A good way to ameliorate these effects is to stay engaged in social activities and continue to use your brains in the same way you did when you were working. In short, we show that if you rest, you rust. <h2>What still isn’t known</h2> Because we are using data and a program in China, the mechanisms of how retirement induces cognitive decline could be context-specific and may not necessarily apply to people in other countries. For example, cultural differences or other policies that can provide support to individuals in old age can buffer some of the negative effects that we see in rural China due to the increase in social isolation and reduced mental activities. Therefore, we can not definitively say that the findings will extrapolate to other countries. We are looking for data from other countries’ retirement programs, such as India’s, to see if the effects are similar or how they are different. <h2>How I do my research</h2> A big focus of the <a href="https://scholar.harvard.edu/pnikolov/my-research-group-1">economics research lab</a> I run is to <a href="http://www.nber.org/%7Enikolovp/research.html">better understand</a> the causes and consequences of changes in what economists call <a href="https://www.britannica.com/topic/human-capital">“human capital”</a> – especially cognitive skills – in the context of developing countries. Our lab’s mission is to generate research to inform economic policies and empower individuals in low-income countries to rise out of poverty. One of the main ways we do this is through the use of randomized controlled trials to measure the impact of a particular intervention, such as retiring early or access to microcredit, on education outcomes, productivity and health decisions. <a href="https://theconversation.com/profiles/plamen-v-nikolov-1112610">Plamen V Nikolov</a>, Assistant Professor of Economics, <a href="https://theconversation.com/institutions/binghamton-university-state-university-of-new-york-2252">Binghamton University, State University of New York</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Breaking the silence on prostate cancer: man’s family legacy highlights importance of early detection

James Murray, 55, an architect from Melbourne, always knew he was living with a genetic "time bomb." A fifth-generation prostate cancer sufferer, his family’s battle with the disease spans over 170 years. From his great-great-grandfather, who chronicled his symptoms in 1847, to his uncles and father who also faced the disease, prostate cancer has been a grim constant in his family. “My family has what's been called a ‘spectacular history’ with prostate cancer,” James reflects. “But that’s not the kind of thing you want to hear. My great-great-grandfather had it, though they couldn’t test for it back then. My grandfather died from it, my father got it, and both of his brothers had it as well. It’s been a constant in our family for generations.” James' great-great-grandfather, Robert William Felton Lathrop Murray, a soldier and the founder of the Hobart Town Gazette, documented his battle with the disease long before modern medicine could provide a diagnosis. Since then, generation after generation of Murrays has grappled with the same fate. For James, however, early detection was key. Diagnosed in February 2022, he underwent surgery just a few months later in May, removing what doctors described as an aggressive form of the disease. But his story, unlike his ancestors, had a different ending. “In a way, we’ve been cursed by prostate cancer," explains James. "But it’s also been a blessing because it made us all hyper-aware of the importance of early detection. My dad was incredibly diligent, and that saved his life. He made sure I was on top of my PSA testing from my mid-40s, and that’s how we caught it early for me.” Prostate-Specific Antigen (PSA) testing and early detection are now recognised as crucial, particularly for men with a family history of prostate cancer. Yet, dangerous myths surrounding prostate cancer testing continue to cost lives, warns Associate Professor Weranja Ranasinghe, Deputy Leader of the Urological Society of Australia and New Zealand’s (USANZ) GU-Oncology Special Advisory Group. “Many men believe that they need to have urinary symptoms to be concerned about prostate cancer,” explains Ranasinghe. “The reality is that most prostate cancers develop without any symptoms at all. Urinary symptoms are not reliable – most of these symptoms are caused by non-cancerous enlargement of the prostate but advanced cancer can also give you urinary symptoms. So it is important to get checked.” An even greater barrier, however, is the outdated belief that prostate cancer screening requires an invasive rectal exam. Ranasinghe stresses that this is no longer the case: “A simple PSA blood test, combined with advanced imaging like MRI, is now the standard approach. Many men are avoiding tests due to this outdated fear, but in the GP setting, a rectal exam is currently not required for detecting prostate cancer." With over 26,000 Australian men expected to be diagnosed with prostate cancer this year, the Urological Society of Australia and New Zealand (USANZ) is raising awareness during Prostate Cancer Awareness Month about the importance of early testing and debunking these misconceptions. Ranasinghe also points out that men with a strong family history should be particularly vigilant. “Men with female relatives who have had breast or ovarian cancer are also at an increased risk of prostate cancer due to the same genetic mutations. So we recommend that men with a strong family history get a PSA test at the age of 40, which is earlier than the recommended age.” For James Murray, the decision to undergo surgery quickly after his diagnosis proved life-saving. “When my PSA levels started rising in February 2022, I wasn’t shocked," he recalls. "I had always known this day would come. It wasn’t something I feared, but more something I was prepared for. I told myself, ‘Okay, it’s here, let’s deal with it,’ and I just focused on getting through the surgery as quickly as possible.” James feels fortunate compared to his uncles, whose diagnoses came much later in life, leading to more severe outcomes. His surgery went well, and he's had a quick recovery, returning to work and feeling grateful that they caught it early. That's why James is advocating for early PSA testing, particularly for men with a family history of prostate cancer. He plans to ensure his 19-year-old son is aware of the need for testing in the future. "We often see men wait until a friend or relative is diagnosed before thinking about getting a prostate cancer PSA test done," says Ranasinghe. "This reactive approach is dangerous. Men need to be proactive and take ownership of their prostate health and talk to their GPs about this, just like they would with cholesterol or other routine health checks." As prostate cancer awareness grows, James hopes his story will encourage others to get tested. It’s something no one wants to face, but the sooner you catch it, the better chance you have.

Jessica Alba surprises dad by buying his childhood home

Jessica Alba has spent the past three years working towards buying her parents a house, but not just any house, she bought her father's childhood home. She took to Instagram to make the announcement, with a teaser video of her special home-renovation project. "Almost three years ago, I started the project of my dreams… I surprised my parents by buying them a house!!" she began. "Now, it wasn't just any house – it was extra sentimental as it was my grandparent's house that my father grew up in," she continued. "After my grandfather passed away, my parents were planning on selling the house in order to pay for my grandmother's medical bills. Well… I pretended like I was going to help them flip it before selling when in reality, I had planned to buy it for them all along." <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/C_TWEyhPyy_/?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/C_TWEyhPyy_/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by Jessica Alba (@jessicaalba)</a> </div> </blockquote> She published the first part of her renovation series on YouTube and in it explained the sentimental value of the house and how it was a symbol for her father, who was an immigrant from Mexico, that "he had made it".

Just 15 centimetres of water can float a car – but we are failing to educate drivers about the dangers of floodwaters

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/amy-peden-1136424">Amy Peden</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> and <a href="https://theconversation.com/profiles/kyra-hamilton-331594">Kyra Hamilton</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a> Every year in Australia, people driving into floodwaters drown and many more are <a href="https://www.ses.nsw.gov.au/disaster-tabs-header/flood/">rescued</a>. Do you know what to do when there’s water on the road? We searched all state and territory learner and driver handbooks for information about floodwaters, including signage. Our findings, published in the <a href="https://www.sciencedirect.com/science/article/pii/S0022437524000860?via%3Dihub">Journal of Safety Research</a>, are disturbing. Across half of Australia’s states and territories, the driver handbook ignores flooding. That’s a missed opportunity, considering the handbook contains road rules and provides advice on how to navigate safely. While some states fail to provide any flood-related information, others give detailed practical guidance. Only the New South Wales handbook includes explanation of the meaning and purpose of flood signage. This is despite almost all states and territories experiencing vehicle-related flood <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1111/jfr3.12616">deaths</a>, including <a href="https://currents.plos.org/disasters/article/causal-pathways-of-flood-related-river-drowning-deaths-in-australia/">drowning</a>, between 2001 and 2017. It’s a major problem that is only going to get worse as the climate changes. So our research shows driver education needs to come up to speed, fast. <h2>Why do people drive into floodwaters?</h2> Our previous <a href="https://www.sciencedirect.com/science/article/abs/pii/S2212420918301869">research</a> revealed motorists can feel compelled to drive into floodwaters for a range of reasons. These include time pressures such as being late for work or school, or needing to get home to family or pets. Sometimes they feel pressured by their passengers, or motorists behind them on the road, urging them to cross. People also report having been encouraged or instructed as learners to drive into floodwaters. Past experience as a passenger also influences a <a href="https://www.sciencedirect.com/science/article/pii/S1369847823000475">learner driver’s</a> future willingness to drive into floodwaters. So the views of significant others, such as their supervising driver, strongly influence decisions around driving into floodwaters. <figure><iframe src="https://www.youtube.com/embed/ZtlXpDBjU1Q?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>Avoid driving into floodwaters, for life’s sake.</figcaption></figure> <h2>What we did and what we found</h2> We assessed all publicly available, government-issued learner and driver handbooks (12 documents) across all six Australian states and two territories. We also looked for flood-related signage. We used a method for reviewing online material through a systematic search including in-document key words and imagery. Four jurisdictions provided no information on flooding in the handbook. In the ACT, South Australia, Tasmania and Victoria, drivers need to look elsewhere for information on floodwaters and driving safety. Only one jurisdiction provided information on flood signage such as depth markers and “road subject to flooding”. Hats off to the <a href="https://www.nsw.gov.au/sites/default/files/2022-11/Road-User-Handbook-English.pdf">NSW Road User Handbook</a>, which warns: <blockquote> Floodwater is extremely dangerous. Find another way or wait until the road is clear. It’s safer to turn around than to drive in floodwater. </blockquote> For the states and territories that did provide information on floodwaters in the handbook, the content varied. NSW, Queensland and the Northern Territory warned against entering floodwaters in a vehicle. They highlighted the dangers and financial penalties associated with driving on closed roads. In the NT and Western Australia, handbooks provided practical information on when and how to cross floodwaters safely, such as how to gauge safe water depth based on vehicle size, and to avoid fast-flowing water. Although well-intentioned, judgements around what constitutes fast-flowing water are subjective and hard for any driver to assess, let alone learner drivers. Even drivers of larger vehicles such as four-wheel drives are regularly involved in flood-related <a href="https://currents.plos.org/disasters/article/causal-pathways-of-flood-related-river-drowning-deaths-in-australia/">vehicle drowning fatalities</a>. Just <a href="https://www.ses.vic.gov.au/news-and-media/campaigns/15-to-float">45cm</a> of water can float a large 4WD, and considerably less for smaller vehicles. <figure><iframe src="https://www.youtube.com/embed/t4ilUbMXZAQ?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>A small car can float in just 15cm of water.</figcaption></figure> Handbooks represent valuable sources of safety information, particularly for new drivers who must learn important road rules to progress from one licence to another. Such graduated driver licensing schemes reduce road traffic injury, particularly among <a href="https://www.sciencedirect.com/science/article/pii/S0022437523000385">young people</a>. However, many of these handbooks fail to provide consistent, practical evidence-based information about flooding. There is an opportunity here to support safer driving behaviours. <h2>Safety tips for all drivers</h2> We encourage drivers to follow these safety tips: <ul> <li>avoid driving into floodwaters</li> <li>identify alternative routes, so you have a <a href="https://theconversation.com/when-roads-become-rivers-forming-a-plan-b-can-stop-people-driving-into-floodwaters-183036">plan B</a></li> <li>familiarise yourself, and any learner drivers in the household or under your care, with the meaning and purpose of flood signage</li> <li>understand the legal consequences of crossing a road closed sign</li> <li>discuss the dangers of driving into floodwaters with learner drivers and help them formulate their own plan B</li> <li>model safe driving for all passengers, including children.</li> </ul> <h2>Time to lift our game</h2> Driving into floodwaters remains the main cause of <a href="https://currents.plos.org/disasters/article/causal-pathways-of-flood-related-river-drowning-deaths-in-australia/">flood-related drowning</a> in Australia. For our emergency service personnel, driver behaviour, including people ignoring road closed signs, <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/hpja.181">significantly complicates</a> the already dangerous act of performing a flood rescue. Extreme weather and flooding are likely to become more frequent and intense in the future. That means the chance of being faced with a flooded road is growing. So information about driving during floods is vital for all, from the newly licensed to the experienced driver. We hope our research will encourage all states and territories to include provide practical, evidence-based advice on floods in driver handbooks as soon as possible.<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/233116/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/amy-peden-1136424">Amy Peden</a>, NHMRC Research Fellow, School of Population Health & co-founder UNSW Beach Safety Research Group, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> and <a href="https://theconversation.com/profiles/kyra-hamilton-331594">Kyra Hamilton</a>, Associate Professor in Applied Psychology, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What is childhood dementia? And how could new research help?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/kim-hemsley-1529322">Kim Hemsley</a>, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a>; <a href="https://theconversation.com/profiles/nicholas-smith-1529324">Nicholas Smith</a>, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a>, and <a href="https://theconversation.com/profiles/siti-mubarokah-1529323">Siti Mubarokah</a>, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a> “Childhood” and “dementia” are two words we wish we didn’t have to use together. But sadly, around <a href="https://doi.org/10.1093/brain/awad242">1,400 Australian children and young people</a> live with currently untreatable childhood dementia. Broadly speaking, childhood dementia is caused by any one of <a href="https://www.childhooddementia.org/what-is-childhood-dementia#what">more than 100</a> rare genetic disorders. Although the causes differ from dementia acquired later in life, the progressive nature of the illness is the same. <a href="https://doi.org/10.1093/brain/awad242">Half</a> of infants and children diagnosed with childhood dementia will not reach their tenth birthday, and most will die <a href="https://www.childhooddementia.org/what-is-childhood-dementia#what">before turning 18</a>. Yet this devastating condition has lacked awareness, and importantly, the research attention needed to work towards treatments and a cure. <h2>More about the causes</h2> Most types of childhood dementia are <a href="https://academic.oup.com/brain/article/146/11/4446/7226999">caused</a> by <a href="https://www.genome.gov/genetics-glossary/Mutation">mutations</a> (or mistakes) in our <a href="https://www.genome.gov/genetics-glossary/Deoxyribonucleic-Acid">DNA</a>. These mistakes lead to a range of rare genetic disorders, which in turn cause childhood dementia. <a href="https://doi.org/10.1093/brain/awad242">Two-thirds</a> of childhood dementia disorders are caused by “<a href="https://www.ncbi.nlm.nih.gov/books/NBK459183/">inborn errors of metabolism</a>”. This means the metabolic pathways involved in the breakdown of carbohydrates, lipids, fatty acids and proteins in the body fail. As a result, nerve pathways fail to function, neurons (nerve cells that send messages around the body) die, and progressive cognitive decline occurs. <h2>What happens to children with childhood dementia?</h2> Most children initially appear unaffected. But after a period of apparently normal development, children with childhood dementia <a href="https://doi.org/10.1016/j.pediatrneurol.2023.09.006">progressively lose</a> all previously acquired skills and abilities, such as talking, walking, learning, remembering and reasoning. Childhood dementia also leads to significant changes in behaviour, such as aggression and hyperactivity. Severe sleep disturbance is common and vision and hearing can also be affected. Many children have seizures. The age when symptoms start can vary, depending partly on the particular genetic disorder causing the dementia, but the average is around <a href="https://doi.org/10.1093%2Fbrain%2Fawad242">two years old</a>. The symptoms are caused by significant, progressive brain damage. <h2>Are there any treatments available?</h2> Childhood dementia treatments currently <a href="https://www.childhooddementia.org/news/report-reveals-global-research-inequity">under evaluation</a> or approved are for a very limited number of disorders, and are only available in some parts of the world. These include gene replacement, <a href="https://doi.org/10.1002/jmd2.12378">gene-modified cell therapy</a> and protein or <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa1712649">enzyme replacement therapy</a>. Enzyme replacement therapy is available in Australia for <a href="https://australianprescriber.tg.org.au/articles/cerliponase-alfa-for-neuronal-ceroid-lipofuscinosis-type-2-disease.html">one form of childhood dementia</a>. These therapies attempt to “fix” the problems causing the disease, and have shown promising results. Other experimental therapies include ones that <a href="https://doi.org/10.3390/life12050608">target</a> faulty protein production or <a href="https://doi.org/10.1056/nejmoa2310151">reduce inflammation</a> in the brain. <h2>Research attention is lacking</h2> Death rates for Australian children with cancer <a href="http://www.childhooddementia.org/getasset/2WX39O">nearly halved</a> between <a href="https://www.aihw.gov.au/reports/children-youth/australias-children/contents/health/cancer-incidence-survival">1997 and 2017</a> thanks to research that has enabled the development of multiple treatments. But over recent decades, <a href="http://www.childhooddementia.org/getasset/2WX39O">nothing has changed</a> for children with dementia. In 2017–2023, research for childhood cancer received over four times more funding per patient compared to funding for <a href="https://www.childhooddementia.org/getasset/2WX39O">childhood dementia</a>. This is despite childhood dementia causing a <a href="https://doi.org/10.1093/brain/awad242">similar number of deaths</a> each year as childhood cancer. The success <a href="https://www.aihw.gov.au/reports/children-youth/australias-children/contents/health/cancer-incidence-survival">for childhood cancer sufferers</a> in recent decades demonstrates how adequately funding medical research can lead to improvements in patient outcomes. Another bottleneck for childhood dementia patients in Australia is the lack of access to clinical trials. An <a href="https://www.childhooddementia.org/news/report-reveals-global-research-inequity">analysis</a> published in March this year showed that in December 2023, only two clinical trials were recruiting patients with childhood dementia in Australia. Worldwide however, 54 trials were recruiting, meaning Australian patients and their families are left watching patients in other parts of the world receive potentially lifesaving treatments, with no recourse themselves. That said, we’ve seen a slowing in the establishment of <a href="https://www.childhooddementia.org/news/report-reveals-global-research-inequity">clinical trials</a> for childhood dementia across the world in recent years. In addition, we know from <a href="https://www.childhooddementia.org/join-us/professionals/impacts">consultation with families</a> that current care and support systems <a href="https://www.childhooddementia.org/getasset/44MLP8">are not meeting the needs</a> of children with dementia and their families. <h2>New research</h2> Recently, we were awarded <a href="https://www.premier.sa.gov.au/media-releases/news-items/major-funding-boost-for-research-into-childhood-dementia">new funding</a> for <a href="https://www.flinders.edu.au/giving/our-donors/impact-of-giving/improving-the-lives-of-children-with-dementia">our research</a> on childhood dementia. This will help us continue and expand studies that seek to develop lifesaving treatments. More broadly, we need to see increased funding in Australia and around the world for research to develop and translate treatments for the broad spectrum of childhood dementia conditions.

"I am lucky to be here": Julie Goodwin opens up on childhood trauma

Julie Goodwin has opened up about the childhood abuse she experienced in her latest memoir. The 53-year-old MasterChef Australia star wrote about how she was sexually abused as a child and later attempted suicide as a teenager in her autobiography, Your Time Starts Now. Speaking to The Australian Women's Weekly, Goodwin recalled how the memory of the abuse which she had buried for a long time returned when she was 16. "Nothing triggered it, it was just like the memory was always there, like a dusty book on a library shelf," she said. "And one day I took it down and looked at it and went, 'Holy crap, how have I not thought about that for nine years?'" Goodwin, however kept the resurfaced memory to her self and maintained an excellent academic record at high school, even becoming school captain, until a year later when she attempted suicide at the age of 17. She shared that following her hospitalisation, she returned to school a few days later and acted as if nothing serious had happened. The TV star then opened up on her road to recovery and the tremendous amount of help she received from her husband Mick, who gave her the love and support she needed. "I am living my second life," she told Women's Weekly. "I am lucky to be here." Images: Channel 10

Early indicators of dementia: 5 behaviour changes to look for after age 50

<a href="https://theconversation.com/profiles/daniella-vellone-1425451">Daniella Vellone</a>, <a href="https://theconversation.com/institutions/university-of-calgary-1318">University of Calgary</a> Dementia is often thought of as a memory problem, like when an elderly person asks the same questions or misplaces things. In reality, individuals with dementia will not only experience issues in other areas of cognition like learning, thinking, comprehension and judgement, but they may also experience <a href="https://www.alzint.org/u/World-Alzheimer-Report-2021.pdf">changes in behaviour</a>. It’s important to understand what dementia is and how it manifests. I didn’t imagine my grandmother’s strange behaviours were an early warning sign of a far more serious condition. She would become easily agitated if she wasn’t successful at completing tasks such as cooking or baking. She would claim to see a woman around the house even though no woman was really there. She also became distrustful of others and hid things in odd places. These behaviours persisted for some time before she eventually received a dementia diagnosis. <h2>Cognitive and behavioural impairment</h2> When cognitive and behavioural changes interfere with an individual’s functional independence, that person is considered to have dementia. However, when cognitive and behavioural changes don’t interfere with an individual’s independence, yet still negatively affect relationships and workplace performance, they are referred to as <a href="https://alzheimer.ca/sites/default/files/documents/other-dementias_mild-cognitive-impairment.pdf">mild cognitive impairment (MCI)</a> and <a href="https://doi.org/10.1186/s13195-021-00949-7">mild behavioural impairment (MBI)</a>, respectively. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9169943/">MCI and MBI can occur together</a>, but in one-third of people who develop Alzheimer’s dementia, the behavioural symptoms come <a href="http://dx.doi.org/10.1016/j.jagp.2019.01.215">before cognitive decline</a>. Spotting these behavioural changes, which emerge in later life (ages 50 and over) and represent a persistent change from longstanding patterns, can be helpful for implementing preventive treatments before more severe symptoms arise. As a medical science PhD candidate, my research focuses on problem behaviours that arise later in life and indicate increased risk for dementia. <h2>Five behavioural signs to look for</h2> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/551071/original/file-20230928-17-jmy46j.png?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/551071/original/file-20230928-17-jmy46j.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/551071/original/file-20230928-17-jmy46j.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=525&fit=crop&dpr=1 600w, https://images.theconversation.com/files/551071/original/file-20230928-17-jmy46j.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=525&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/551071/original/file-20230928-17-jmy46j.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=525&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/551071/original/file-20230928-17-jmy46j.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=659&fit=crop&dpr=1 754w, https://images.theconversation.com/files/551071/original/file-20230928-17-jmy46j.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=659&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/551071/original/file-20230928-17-jmy46j.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=659&fit=crop&dpr=3 2262w" alt="Illustration of five behaviour changes that may indicate risk of dementia" /></a><figcaption>Spotting behavioural changes can be helpful for implementing preventive treatments before more severe symptoms arise. (Daniella Vellone)</figcaption></figure> There are <a href="https://doi.org/10.3233%2FJAD-160979">five primary behaviours</a> we can look for in friends and family who are over the age of 50 that <a href="https://doi.org/10.1186/s13024-023-00631-6">might warrant further attention</a>. <h2>1. Apathy</h2> <a href="https://doi.org/10.1002%2Ftrc2.12370">Apathy</a> is a decline in interest, motivation and drive. An apathetic person might lose interest in friends, family or activities. They may lack curiosity in topics that normally would have interested them, lose the motivation to act on their obligations or become less spontaneous and active. They may also appear to lack emotions compared to their usual selves and seem like they no longer care about anything. <h2>2. Affective dysregulation</h2> <a href="https://doi.org/10.1016/j.jad.2023.03.074">Affective dysregulation</a> includes mood or anxiety symptoms. Someone who shows affective dysregulation may develop sadness or mood instability or become more anxious or worried about routine things such as events or visits. <h2>3. Lack of impulse control</h2> <a href="https://doi.org/10.1002%2Ftrc2.12016">Impulse dyscontrol</a> is the inability to delay gratification and control behaviour or impulses. Someone who has impulse dyscontrol may become agitated, aggressive, irritable, temperamental, argumentative or easily frustrated. They may become more stubborn or rigid such that they are unwilling to see other views and are insistent on having their way. Sometimes they may develop sexually disinhibited or intrusive behaviours, exhibit repetitive behaviours or compulsions, start gambling or shoplifting, or experience difficulties regulating their consumption of substances like tobacco or alcohol. <h2>4. Social inappropriateness</h2> <a href="http://dx.doi.org/10.1017/S1041610217001260">Social inappropriateness</a> includes difficulties adhering to societal norms in interactions with others. Someone who is socially inappropriate may lose the social judgement they previously had about what to say or how to behave. They may become less concerned about how their words or actions affect others, discuss private matters openly, talk to strangers as if familiar, say rude things or lack empathy in interactions with others. <h2>5. Abnormal perceptions or thoughts</h2> <a href="https://doi.org/10.1038/s44220-023-00043-x">Abnormal perception or thought content</a> refers to strongly held beliefs and sensory experiences. Someone with abnormal perceptions or thoughts may become suspicious of other people’s intentions or think that others are planning to harm them or steal their belongings. They may also describe hearing voices or talk to imaginary people and/or act like they are seeing things that aren’t there. Before considering any of these behaviours as a sign of a more serious problem, it’s important to rule out other potential causes of behavioural change such as drugs or medications, other medical conditions or infections, interpersonal conflict or stress, or a recurrence of psychiatric symptoms associated with a previous psychiatric diagnosis. If in doubt, it may be time for a doctor’s visit. <h2>The impact of dementia</h2> Many of us know someone who has either experienced dementia or cared for someone with dementia. This isn’t surprising, given that dementia is predicted to affect <a href="https://www.ctvnews.ca/health/nearly-one-million-canadians-will-live-with-dementia-by-2030-alzheimer-society-predicts-1.6056849#:">one million Canadians by 2030</a>. While people between the ages of 20 and 40 may think that they have decades before dementia affects them, it’s important to realize that dementia isn’t an individual journey. In 2020, care partners — including family members, friends or neighbours — spent <a href="https://alzheimer.ca/sites/default/files/documents/Landmark-Study-1-Path-Forward-Alzheimer-Society-of-Canada-2022-wb.pdf">26 hours per week</a> assisting older Canadians living with dementia. This is equivalent to 235,000 full-time jobs or $7.3 billion annually. These numbers are expected to triple by 2050, so it’s important to look for ways to offset these predicted trajectories by preventing or delaying the progression of dementia. <h2>Identifying those at risk</h2> While there is currently no cure for dementia, there has been progress towards <a href="https://alzheimer.ca/en/about-dementia/dementia-treatment-options-developments">developing effective treatments</a>, which <a href="https://alzheimer.ca/en/about-dementia/do-i-have-dementia/how-get-tested-dementia-tips-individuals-families-friends/10">may work better earlier in the disease course</a>. More research is needed to understand dementia symptoms over time; for example, the online <a href="https://www.can-protect.ca/">CAN-PROTECT study</a> assesses many contributors to brain aging. Identifying those at risk for dementia by recognizing later-life changes in cognition, function as well as behaviour is a step towards not only preventing consequences of those changes, but also potentially preventing the disease or its progression.<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/213954/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/daniella-vellone-1425451">Daniella Vellone</a>, Medical Science and Imaging PhD Candidate, <a href="https://theconversation.com/institutions/university-of-calgary-1318">University of Calgary</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Princess Diana's childhood home up for rent

The house Princess Diana spent her childhood and teenage years in is now available for the public to rent. Althorp House, located in West Northamptonshire in England, is owned by Diana's brother Earl Spencer, who has lived on the sprawling property as custodian of the estate since 1992. The expansive property has been listed for royal fans with deep pockets to rent on <a href="https://www.elysian-estates.co.uk/althorp/" target="_blank" rel="noopener">Elysian Estates</a>, an upmarket equivalent of Airbnb. Althorp House, which is a 90 minute drive out of London, was built in 1508 and has been in the Spencer family for 19 generations. Lady Diana lived in the 90-room stately home for most of her childhood and teenage years, before she married the then-Prince Charles in 1981. Not just one grand property, the estate covers 13,000 acres of countryside as it encompasses cottages, farms, woodlands and villages, which are open to visitors but only at certain times of the year. Now, the home is once again available to rent via Elysian Estates. "Althorp offers unparalleled levels of service, privacy and luxury to rival the finest properties anywhere in the world; yet retains the truly welcoming and homely feel that makes Althorp so special," the listing says. "Walk in the footsteps of kings and queens, feast or celebrate in spectacular surroundings, marvel at the sense of history and artwork, and slumber in pure luxury." In the main house, there are six state bedrooms to choose from offering "a level of opulence befitting royalty, with these very rooms playing as much a part of English history as any royal palace". Prices for the rental are not yet publicly available as an enquiry must be sent to reserve the opulent property. The listing stated that the stay includes "butler service, a team of private chefs and housekeeping, with a dedicated concierge service". Althorp is today most famous for being the final resting place of Princess Diana following her death in Paris. Image credits: Getty Images / Instagram

"His hero narrative has massively failed": Qantas staff's brutal response to Alan Joyce's early exit

A former Qantas pilot and several current staff members have recounted the moment they found out about now former-CEO Alan Joyce's early exit from the company. Joyce was planning to retire from his CEO role in November, but shocked the nation on <a href="https://oversixty.com.au/finance/legal/alan-joyce-announces-shock-early-departure" target="_blank" rel="noopener">Tuesday</a> when he decided he would be stepping back, effective immediately. His resignation comes after 22 years in the role, as Qantas continues to face mounting pressures over unprecedented customer dissatisfaction, and a looming glass action lawsuit over cancelled flights. Upon hearing the news, past and present Qantas employees erupted in celebration. Retired Qantas pilot captain Richard de Crespigny was on board a flight on Tuesday when the news broke mid-air that Joyce was gone, sparking extraordinary celebrations. "I was on a flight from Sydney to Melbourne this morning and when I landed the cabin crew were giving each other high-fives," de Crespigny told <a href="https://9now.nine.com.au/a-current-affair/former-qantas-pilot-richard-de-crespigny-speaks-out-following-ceo-alan-joyce-resignation/18040563-db75-41c4-af7c-b5ed8af84bf6" target="_blank" rel="noopener">A Current Affair</a>. Another ground staff member said, "We're celebrating wildly, not just because he's leaving but because his hero narrative has massively failed." Mr de Crespigny, who worked for Qantas for 34 years warned the airline won't regain trust overnight just because Joyce has taken off. "It's built in teaspoons and destroyed in shovel loads," he said. "It takes incredible skill, determination and empathy to build it up; it's got to be protected." Mr de Crespigny went on to say the Qantas business restructure after the travel industry was decimated by the Covid pandemic was not good enough, and the upper management made some terrible decisions. During the pandemic, Mr Joyce locked out employees during an industrial dispute before hundreds of staff lost their jobs during the Covid-19 pandemic. "Some of them didn't come out of it well at all. They lost their jobs, they lost their houses, they lost their marriages," de Crespigny said. "The workers that held Qantas up … they really suffered greatly." "And it hasn't been a good vision to see the executive team, the CEO, continue to get bonuses at the expense of maybe baggage handlers and other people that have lost their jobs. This is not a good example of leadership." Image credits: A Current Affair

Alan Joyce announces shock early departure

Qantas CEO Alan Joyce is stepping down from his position earlier than anticipated, following a period of mounting public and regulatory pressure on the national airline. After dedicating 22 years to Qantas, with a 15-year tenure as its chief executive, Joyce's last day in office was confirmed by Qantas in a statement to the ASX. The airline has been mired in a series of negative headlines for several months, including <a href="https://www.oversixty.com.au/finance/money-banking/alan-joyce-grilled-over-cancelled-flights-and-covid-credits" target="_blank" rel="noopener">allegations of selling tickets for nonexistent flights</a>, exorbitant airfares, high cancellation rates and issues related to <a href="https://www.oversixty.com.au/finance/money-banking/alan-joyce-grilled-over-cancelled-flights-and-covid-credits" target="_blank" rel="noopener">flight credits</a>. Vanessa Hudson, the incoming leader designated to fill Joyce's shoes, will now take on the role of managing director and group chief executive, effective from Wednesday August 6. This unexpected announcement was made on Tuesday morning, with Mr. Joyce stating, "In the last few weeks, the focus on Qantas and events of the past make it clear to me that the company needs to move ahead with its renewal as a priority. "The best thing I can do under these circumstances is to bring forward my retirement and hand over to Vanessa and the new management team now, knowing they will do an excellent job. "There is a lot I am proud of over my 22 years at Qantas, including the past 15 years as CEO. There have been many ups and downs, and there is clearly much work still to be done, especially to make sure we always deliver for our customers. But I leave knowing that the company is fundamentally strong and has a bright future." Qantas Chairman Richard Goyder expressed gratitude to Joyce for his years of service and leadership but acknowledged that the transition is occurring during a challenging period for Qantas. Joyce's decision to step down came shortly after the Australian Competition and Consumer Commission initiated legal action against the airline, accusing it of selling tickets for over 8,000 flights scheduled between May and July of the previous year, even after those flights had been cancelled.

Jackie O reveals awful nickname she was given in her early career days

Jackie O Henderson has recalled the awful nickname she was given by upper radio management at the start of her career. The 48-year-old started her career in the media after ringing a station to win Guns N' Roses concert tickets, which led to a role answering phones for the station. Chatting candidly on The Kyle and Jackie O Show, she revealed, "I was called "Jackie the Phone Tart'." The nickname was perpetuated by an influx of hate from some radio listeners, particularly boy band fans who mistakenly believed she was sleeping with their idols when they came into the station for interviews. "I'd get all this hate [from fans] because my name was "tart" and they all thought, 'Oh, she's in there making moves, you know, being a sl*t'." "So I changed [my nickname]," added the radio host. Jackie has previously explained that while she was living on the Gold Coast as a teenager, she would call up the local Sea FM station in the early 90s in a bid to score concert tickets from radio host 'Ugly' Phil O'Neil. "I never worked at Sea FM," she said, adding that Ugly Phil took her out "on a date" after asking her to come and visit the radio station and collect the concert tickets she had won. Jackie recalled the pair had only been together for three months before he was offered a radio job in Canberra. "I moved with him because we were in a relationship," she added. The couple then relocated to Adelaide where Jackie got offered a job "on the phones" at the station where Phil hosted a show. "The rest is history," Jackie said. Image credits: Instagram

Sickness or health: Healthy life split along gender, education lines

Australians are living and working longer than ever, but the number of healthy years they’re enjoying with this added longevity isn’t shared equally between the sexes, or by those who finished school before Year 12. <div class="copy"> A paper recently <a href="https://doi.org/10.1016/S2468-2667(23)00129-9" target="_blank" rel="noreferrer noopener" data-type="URL" data-id="https://doi.org/10.1016/S2468-2667(23)00129-9">published</a> in The Lancet Public Health from the Ageing Futures Institute at the University of New South Wales shows an increase in longevity in Australia. Other data in the publication reveal detail about “healthy years”. Men, and those with higher levels of education, worked about 2 years longer in good health. For women and those with lower education, the years of healthy life expectancy have gone backwards. The report, led by statistician Dr Kim Kiely who is now based at The University of Wollongong, compared representative cohorts of people aged 50-100 who participated in the Household Income and Labour Dynamics in Australia survey (HILDA). Those cohorts were measured over decade long periods – the first from 2001-2010 and the second from 2011-2020. Men added an extra 11 months of healthy life between the cohorts, while women lost a month. Similarly those of any gender who had completed year 12 added about 10 months to their healthy life expectancy, while the same amount of time was lost by those who hadn’t. “Everyone’s increasing their working life expectancy, so the years they’re expected to be working,” Kiely says. “What is different is how long they’re expected to be living in good health: women and people with low education didn’t have an improvement in healthy life expectancy. “Everyone’s also living longer than ever before, but for women, those extra years seem to be years of poor health. People with lower education – they end up going backwards, they’re losing years of healthy life.” Australia’s working life trends are similar to those in Europe and the UK, though this research suggests the Australian labour force works longer in poor health than their antipodean counterparts. Kiely says the findings are important considerations for policymakers pondering questions of retirement and pension ages: the demands of some labour may not be evenly spread when it comes to considering health implications. “We have a pension age that has been rising steadily over the past couple of decades – it’s not rising anymore – but there is a strong expectation for people to be working longer,” Kiely says. “And if that is the case, then we need opportunities for work for mature age, older adults, and those work opportunities have to be suitable for their capacity to work. “We do need to address things like age and gender discrimination in the workforce. And we need to think about how we support people who are unable to work before they reach the pension age.” Kiely is extending his research into how the nature of work in Australia influences these high-level findings. He hopes this can explain why gender and education influence healthy working years. Further drilling down into other subgroups is important, say Dr Marty Lynch and Dr Ross Wilkie from Keele University, UK. They investigated healthy working life expectancy as part of Britain’s Independent State Pension Age Review last year. They too found Briton were working longer, but not at a rate that keeps pace with the national pension age. In a Lancet editorial accompanying the Australian research, they point out that the HILDA data evaluation only shows changes in average ages on gender and education lines. “The extent of HWLE [Healthy Working Life Expectancy] inequalities between subpopulations with multiple specific characteristics are likely to be even wider and will also indicate targets and interventions to increase the number of years that people can be healthy and in work,” they say. The impact of socioeconomic status on life expectancy and disease burden was recently highlighted in a large-scale review of Australia’s 30-year health data. <a href="https://cosmosmagazine.com/people/society/australias-life-expectancy-is-up-but-healthy-years-are-a-different-story/">It found</a> while Australians have added 6 years to their life expectancy since 1990, those with lower socioeconomic backgrounds had a higher risk of death-causing disease.

This is the healthiest time to eat dinner

When should we eat dinner? Recent research highlights that the timing of our meals, particularly the last meal of the day, can significantly affect our health. The story is not merely about what we consume, but also about when we do so. The debate about dinner timing finds substantial scientific backing with a Brigham and Women’s Hospital (BWH) study published in Cell Metabolism in October 2022, suggesting that early dinners could have more health benefits than previously believed. The science of early dinner Senior author of the study, Dr Frank A. J. L. Scheer, Director of the Medical Chronobiology Programme in BWH’s Division of Sleep and Circadian Disorders, explained the study’s objective in a press release: “We wanted to test the mechanisms that may explain why late eating increases obesity risk.” The study defined an early dinner as a meal consumed three to four hours before bedtime, aligning with our body’s circadian rhythm. This time management allows the body to efficiently digest food, process nutrients, and smoothly transition into a fasting mode during sleep, facilitating essential restorative processes (and arguably better sleep, according to some experts). The benefits of an early-bird dinner The BWH study discovered stark differences in metabolic profiles of early and late diners. Early diners demonstrated lower blood glucose levels, improved fat-burning capacity, better sleep quality, and higher energy levels. Meanwhile, late dinners led to increased hunger, slower calorie burning, and elevated fat storage, posing risks for conditions like diabetes and cardiovascular disease. Further reinforcing these findings, a study published in Obesity Reviews examined the effects of energy intake distribution on weight loss. This systematic review evaluated nine randomised controlled trials and concluded that focusing on earlier energy intake resulted in significantly greater short-term weight loss. Alongside weight loss, improvements were observed in insulin resistance, fasting glucose and LDL cholesterol levels. Implications and recommendations These findings hold considerable implications for those dealing with health conditions like diabetes, thyroid issues, polycystic ovarian disease, and cardiovascular disorders. The studies spotlight the importance of early and light dinners, thus prompting a re-evaluation of our dinner schedules and meal planning. As first author Dr Nina Vujovic put it: “Does the time that we eat matter when everything else is kept consistent? And we found that eating four hours later makes a significant difference for our hunger levels, the way we burn calories after we eat, and the way we store fat.” Tailoring dinner time to fit your schedule The exact timing of dinner isn’t a one-size-fits-all scenario, as people’s routines vary widely. Nutritionist Maya Feller emphasises that our schedules – ranging from traditional nine-to-five to round-the-clock – are pivotal when considering “ideal” meal times. Therefore, finding a dinner time that seamlessly fits into your schedule is essential, rather than adhering to a strict, potentially unfeasible timetable. Dr Wendy Bazilian offers insightful tips for those whose routines may not accommodate an early dinner. She recommends consuming meals or snacks every three to five hours. This regular eating pattern can help stabilise blood sugar levels, preventing the onset of hunger pangs and energy lulls. Furthermore, it’s advantageous to leave a gap of two to three hours between your last meal and bedtime. This gap ensures your body has sufficient time for most of the digestion process – letting you get adequate rest and repair during sleep. Health benefits The takeaway from these studies is clear: an earlier dinnertime might confer multiple health benefits, from metabolic health enhancement to improved sleep quality. It’s time to reconsider not just the contents of your plate, but also the clock. As research grows, it’s becoming apparent that understanding the interplay between our eating habits, their timing, and the body’s internal clock should be an integral part of our health strategies. After all, leading a healthy lifestyle isn’t solely about counting calories but also understanding when and how to fuel our bodies.

Princess Mary's eldest son make surprising announcement about his future

The eldest son of Princess Mary and Prince Frederik has made a surprising announcement ahead of his 18th birthday. Denmark's Prince Christian has broken years of royal tradition, saying he has decided to forego his royal allowance and instead prioritise his education. One he turns 18 in October, Christian will be able to receive his royal allowance and government funding. However, he has decided to put his education first and postpone becoming a full-time royal until he turns 21. A statement posted on the Royal House’s Instagram page explained that his primary focus in the coming year will be completing his upper secondary education. The statement reads, "Prince Christian's main priority in the coming year will be completing high school education. Following this, the Royal House will orient Prince Christian's further youth and education course, when the time comes." "It has thus been agreed with the Ministry of State that support in the Danish Parliament for a law on annual pension will only be sought when the Prince turns 21 or by a possible change of the throne, if it takes place before." The statement further shared that Prince Christian intends to stay away from the spotlight for now, but he will eventually resume public appearances in an official capacity once he has completed his education.

Australia’s richest schools revealed

Funding in education is a divisive topic at the best of times, but with new data from the Australian Curriculum, Assessment and Reporting Authority’s MySchool, the divide between public and private school has never been more apparent. With five years’ worth of financial data at its disposal, news.com.au ranked Australia’s schools by wealth in each state, and by combining each institution’s gross income across its fees, its government funding, and the likes of donation income. According to the study, the top five wealthiest schools in New South Wales were - from first to fifth - Wahroonga’s Knox Grammar School, Darlinghurst’s Sydney Grammar School, Hornsby’s Barker College, Bellevue Hill’s The Scots College, and Pymble’s Pymble Ladies’ College. The results also revealed that New South Wales’ wealthiest school - Knox Grammar School - has gained more money through fees, funding, and donations over the course of five years than the total economic output of five of Australia’s Pacific island neighbours. Non-government schools account for 56 of the state’s richest, with Cherrybrook Technology High School - a secondary school in northwest Sydney - the highest-earning public school. Victoria’s top five were Keysborough’s Haileybury College, Melbourne’s Wesley College, St Kilda East’s Caulfield Grammar School, Kew’s Carey Baptist Grammar School, and Ivanhoe’s Ivanhoe Grammar School. And Victoria’s richest - Haileybury College - has more money than the bottom 300 schools combined, according to new data, with a staggering five-year income of $677m. However, it has also been reported that many Victorian state schools receive more per student from the government than the top private schools. Similar to Victoria, Queensland’s top five made more money over a five year period than the bottom 300, prompting renewed calls for the state and federal governments to negotiate on school funding. And those top five were Brisbane’s Brisbane Grammar School, East Brisbane’s Anglican Church Grammar School, Indooroopilly’s St Peters Lutheran College, Reedy Creek’s King’s Christian College, and Brisbane’s Brisbane Girls Grammar School. South Australia’s top five were St Peters’ St Peters’ College, Somerton Park’s Sacred Heart College, Marion’s Westminster School, Findon’s Nazareth Catholic College, and Kent Town’s Prince Alfred College. The findings revealed that some of the inner-city colleges were bringing in up to 100 times more than their country school counterparts, and that St Peter’s College could boast a five-year gross income of almost a quarter of a billion dollars. Meanwhile, at small town Port Neill Primary School on the Eyre Peninsula, the gross income for the same period came in at just over $2.5m. Tasmania’s top five were North Hobart’s The Friends’ School, Prospect Vale’s St Patrick’s College, Newstead’s Scotch Oakburn College, Sandy Bay’s The Hutchins School, and Launceston’s Launceston College. And Tasmania’s richest, The Friends’ School, was revealed to be raking in over $158.3m over five years, with an astounding average cost per student of $29,070. The Northern Territory’s top five wealthiest schools were The Garden’s Darwin High School, Humpty Doo’s Taminmin College, Howard Springs’ Good Shepherd Lutheran College, Wadeye’s Our Lady of the Sacred Heart Thamarrurr Catholic College, and Rapid Creek’s The Essington School. Darwin High School had a gross income of $118.1m, while the region’s second wealthiest - Taminmin College - had one just shy of the former’s at $118m. However, Tipperary Station School had the lowest gross income of any of the territory’s schools, bringing in just $2.1m. Western Australia’s top five were Claremont’s Christ Church Grammar School, Wembley Downs’ Hale School, Swanbourne’s Scotch College, Karrinyup’s St Mary’s Anglican Girls’ School, and Duncraig’s St Stephen’s School. And last but not least, the Australian Capital Territory’s five richest schools were Red Hill’s Canberra Grammar School, Bruce’s Radford College, Deakin’s Canberra Girls Grammar School, Isabella Plains’ St Mary MacKillop College, and Pearce’s Marist College Canberra.

How traditional Indigenous education helped four lost children survive 40 days in the Amazon jungle

<a href="https://theconversation.com/profiles/eliran-arazi-1447346">Eliran Arazi</a>, <a href="https://theconversation.com/institutions/hebrew-university-of-jerusalem-855">Hebrew University of Jerusalem</a> The discovery and rescue of <a href="https://www.reuters.com/world/americas/four-missing-colombian-children-found-alive-jungle-sources-2023-06-10/">four young Indigenous children</a>, 40 days after the aircraft they were travelling in crashed in the remote Colombian rainforest, was hailed in the international press as a “<a href="https://www.lemonde.fr/en/international/article/2023/06/11/miracle-in-the-jungle-colombia-celebrates-rescue-of-children-lost-in-amazon-rainforest_6030840_4.html">miracle in the jungle</a>”. But as an anthropologist who has spent more than a year living among the Andoque people in the region, <a href="https://www.academia.edu/100474974/Amazonian_visions_of_Visi%C3%B3n_Amazon%C3%ADa_Indigenous_Peoples_perspectives_on_a_forest_conservation_and_climate_programme_in_the_Colombian_Amazon">conducting ethnographic fieldwork</a>, I cannot simply label this as a miraculous event. At least, not a miracle in the conventional sense of the word. Rather, the survival and discovery of these children can be attributed to the profound knowledge of the intricate forest and the adaptive skills passed down through generations by Indigenous people. During the search for the children, I was in contact with Raquel Andoque, an elder maloquera (owner of a ceremonial longhouse), the sister of the children’s great-grandmother. She repeatedly expressed her unwavering belief the children would be found alive, citing the autonomy, astuteness and physical resilience of children in the region. Even before starting elementary school, children in this area accompany their parents and elder relatives in various activities such as gardening, fishing, navigating rivers, hunting and gathering honey and wild fruits. In this way the children acquire practical skills and knowledge, such as those demonstrated by Lesly, Soleiny, Tien and Cristin during their 40-day ordeal. Indigenous children typically learn from an early age how to open paths through dense vegetation, how to tell edible from non-edible fruits. They know how to find potable water, build rain shelters and set animal traps. They can identify animal footprints and scents – and avoid predators such as jaguars and snakes lurking in the woods. Amazonian children typically lack access to the sort of commercialised toys and games that children in the cities grow up with. So they become adept tree climbers and engage in play that teaches them about adult tools made from natural materials, such as oars or axes. This nurtures their understanding of physical activities and helps them learn which plants serve specific purposes. <figure class="align-center "><img src="https://images.theconversation.com/files/532019/original/file-20230614-31-hrdd5z.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/532019/original/file-20230614-31-hrdd5z.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=450&fit=crop&dpr=1 600w, https://images.theconversation.com/files/532019/original/file-20230614-31-hrdd5z.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=450&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/532019/original/file-20230614-31-hrdd5z.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=450&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/532019/original/file-20230614-31-hrdd5z.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=566&fit=crop&dpr=1 754w, https://images.theconversation.com/files/532019/original/file-20230614-31-hrdd5z.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=566&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/532019/original/file-20230614-31-hrdd5z.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=566&fit=crop&dpr=3 2262w" alt="A youg girl holding up an insect as her family works alongside" /><figcaption>A local Indigenous girl on an excursion to gather edible larvae.

Gadiel Levi, Author provided</figcaption></figure> Since the large rivers in most parts of the Amazon flow in a direction opposite to that of the sun, people can orient themselves towards those main rivers. The trail of footprints and objects left by the four children revealed their general progression towards the Apaporis River, where they may have hoped to be spotted. The children would also have learned from their parents and elders about edible plans and flowers – where they can be found. And also the interrelationship between plants, so that where a certain tree is, you can find mushrooms, or small animals that can be trapped and eaten. <h2>Stories, songs and myths</h2> Knowledge embedded in mythic stories passed down by parents and grandparents is another invaluable resource for navigating the forest. These stories depict animals as fully sentient beings, engaging in seduction, mischief, providing sustenance, or even saving each other’s lives. While these episodes may seem incomprehensible to non-Indigenous audiences, they actually encapsulate the intricate interrelations among the forest’s countless non-human inhabitants. Indigenous knowledge focuses on the interrelationships between humans, plants and animals and how they can come together to preserve the environment and prevent irreversible ecological harm. This sophisticated knowledge has been developed over millennia during which Indigenous people not only adapted to their forest territories but actively shaped them. It is deeply ingrained knowledge that local indigenous people are taught from early childhood so that it becomes second nature to them. It has become part of the culture of cultivating and harvesting crops, something infants and children are introduced to, as well as knowledge of all sort of different food sources and types of bush meat. <h2>Looking after each other</h2> One of the aspects of this “miraculous” story that people in the west have marvelled over is how, after the death of the children’s mother, the 13-year-old Lesly managed to take care of her younger siblings, including Cristin, who was only 11 months old at the time the aircraft went down. <figure class="align-center "><img src="https://images.theconversation.com/files/532007/original/file-20230614-19-7q92j0.jpeg?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/532007/original/file-20230614-19-7q92j0.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=450&fit=crop&dpr=1 600w, https://images.theconversation.com/files/532007/original/file-20230614-19-7q92j0.jpeg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=450&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/532007/original/file-20230614-19-7q92j0.jpeg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=450&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/532007/original/file-20230614-19-7q92j0.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=566&fit=crop&dpr=1 754w, https://images.theconversation.com/files/532007/original/file-20230614-19-7q92j0.jpeg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=566&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/532007/original/file-20230614-19-7q92j0.jpeg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=566&fit=crop&dpr=3 2262w" alt="Three Indigenous people in western clothes stood under trees in front of a wide building." /><figcaption>Iris Andoque Macuna with her brother Nestor Andoque and brother-in-law Faustino Fiagama after the two men returned from the search team. Iris Andoque Macuna., Author provided</figcaption></figure> But in Indigenous families, elder sisters are expected to act as surrogate mothers to their younger relatives from an early age. Iris Andoke Macuna, a distant relative of the family, told me: <blockquote> To some whites [non-Indigenous people], it seems like a bad thing that we take our children to work in the garden, and that we let girls carry their brothers and take care of them. But for us, it’s a good thing, our children are independent, this is why Lesly could take care of her brothers during all this time. It toughened her, and she learned what her brothers need. </blockquote> <h2>The spiritual side</h2> For 40 days and nights, while the four children were lost, elders and shamans performed rituals based on traditional beliefs that involve human relationships with entities known as dueños (owners) in Spanish and by various names in native languages (such as i'bo ño̰e, meaning “persons of there” in Andoque). These owners are believed to be the protective spirits of the plants and animals that live in the forests. Children are introduced to these powerful owners in name-giving ceremonies, which ensure that these spirits recognise and acknowledge relationship to the territory and their entitlement to prosper on it. <figure class="align-center "><img src="https://images.theconversation.com/files/531997/original/file-20230614-15389-7c6oly.JPG?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/531997/original/file-20230614-15389-7c6oly.JPG?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=400&fit=crop&dpr=1 600w, https://images.theconversation.com/files/531997/original/file-20230614-15389-7c6oly.JPG?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=400&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/531997/original/file-20230614-15389-7c6oly.JPG?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=400&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/531997/original/file-20230614-15389-7c6oly.JPG?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=503&fit=crop&dpr=1 754w, https://images.theconversation.com/files/531997/original/file-20230614-15389-7c6oly.JPG?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=503&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/531997/original/file-20230614-15389-7c6oly.JPG?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=503&fit=crop&dpr=3 2262w" alt="Woman in pink t-shirt sat on chair inside." /><figcaption>Raquel Andoke, a relative of the missing children and friend of the author. Image courtesy of Eliran Arazi, Author provided</figcaption></figure> During the search for the missing children, elders conducted dialogues and negotiations with these entities in their ceremonial houses (malocas) throughout the <a href="https://www.researchgate.net/figure/Middle-and-Lower-Caqueta-River-region-State-of-Amazonas-Colombia-Map-from_fig1_255580310">Middle Caquetá</a> and in other Indigenous communities that consider the crash site part of their ancestral territory. Raquel explained to me: <blockquote> The shamans communicate with the sacred sites. They offer coca and tobacco to the spirits and say: “Take this and give me my grandchildren back. They are mine, not yours.” </blockquote> These beliefs and practices hold significant meaning for my friends in the Middle Caquetá, who firmly attribute the children’s survival to these spiritual processes rather than the technological means employed by the Colombian army rescue teams. It may be challenging for non-Indigenous people to embrace these traditional ideas. But these beliefs would have instilled in the children the faith and emotional fortitude crucial for persevering in the struggle for survival. And it would have encouraged the Indigenous people searching for them not to give up hope. The children knew that their fate did not lie in dying in the forest, and that their grandparents and shamans would move heaven and earth to bring them back home alive. Regrettably, this traditional knowledge that has enabled Indigenous people to not only survive but thrive in the Amazon for millennia is under threat. Increasing land encroachment for agribusiness, mining, and illicit activities as well as state neglect and interventions without Indigenous consent have left these peoples vulnerable. It is jeopardising the very foundations of life where this knowledge is embedded, the territories that serve as its bedrock, and the people themselves who preserve, develop, and transmit this knowledge. Preserving this invaluable knowledge and the skills that bring miracles to life is imperative. We must not allow them to wither away.<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/207762/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/eliran-arazi-1447346">Eliran Arazi</a>, PhD researcher in Anthropology, Hebrew University of Jerusalem and the School for Advanced Studies in the Social Sciences (Paris)., <a href="https://theconversation.com/institutions/hebrew-university-of-jerusalem-855">Hebrew University of Jerusalem</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

9 ways to exercise your brain

While many people can say they are dedicated to keeping their bodies in shape, exercising applies to more than just the muscles, bones and fat in our bodies. We should all be working out the neural pathways and connections in our brains too. So whether you’re trying to get your brain back into shape or you just want to keep it as strong as it is now, below are some top tips on how to help exercise your mind to good health. 1. Read as much as you can Whether it’s a newspaper, magazine or book, reading is a fantastic basic brain exercise. Remember, the more challenging the reading material is the more of a workout you are giving your brain. Like with any new exercise regime, start small and work your way up to a level that you find challenging. 2. Learn new words Increasing your vocabulary is a great way to exercise the language portion of your brain. A word-of-the day calendar is a great way to ensure you keep on top of this throughout the year. 3. Put pen to paper (not fingers to a keyboard) From fictional stories to keeping a journal, writing is a good workout for the brain, as it requires lots of thinking. A study published in the Human Brain Mapping journal found that both planning and writing a story by hand combines handwriting and cognitive writing processes, which are predominantly associated with memory and integrating information from diverse sources. 4. Do puzzles Easy to fit into your daily schedule, simple puzzles like crosswords and Sudoku help to get your brain doing some basic work, while more complex puzzles will give your brain a stronger workout. So although more complicated puzzles may take days to solve and complete, they’re worth the effort as these types of games can help keep you sharp, as well as slow memory loss and mental decline. 5. Switch to your non-dominant hand While this might sound like an odd one, switching to your non-dominant hand from time to time has been shown to stimulate the parts of the brain that control your muscles. Experts also say that using your other hand helps your brain to better integrate its two hemispheres. 6. Get talking For a basic brain workout, get chatting! Next time you catch up with family or friends try talking about more challenging topics (such as politics, religion etc.) where you engage in deep discussion – without arguing. It’s a great way to keep your mind active while having fun, get to know others better and to share your thoughts. 7. Back to school Education has obvious benefits and going back to school is a great way to get your brain working again, to challenge yourself and to do something satisfying. You don’t have to sign up for a whole degree, there are many free short courses as well as certificate courses that you can do online. 8. Eat well Just like with the body, when you exercise you need to give your brain the right fuel so it operates at optimal health. The Open Training Institute says, “Skipping breakfast can reduce thinking skills by 40 per cent, as your brain is starved of that much needed sugar hit”. Furthermore, certain foods are good for improving brain function like dark chocolate, which increases blood flow to the brain increasing alertness and clarity. “Blueberries for example pack a powerful punch of antioxidants and can improve memory, while green leafy veggies and fresh herbs are full of vitamin K, which improves cognitive function.” 9. Exercise Being active doesn’t only keep your body healthy it can also make you more alert. The Open Training Institute says, “Low-intensity exercise like yoga or walking can dramatically reduce sleepiness, amp up energy levels and attention span.” And the benefits of keeping active don’t stop there. “More intensity can even improve cognitive function by five to 10 per cent.” Image credit: Shutterstock For information about the Open Training Institute and the courses on offer, or to simply ask a question, call 1300 915 692.

Here’s how a new AI tool may predict early signs of Parkinson’s disease

In 1991, the world was shocked to learn actor <a href="https://www.theguardian.com/film/2023/jan/31/still-a-michael-j-fox-movie-parkinsons-back-to-the-future">Michael J. Fox</a> had been diagnosed with Parkinson’s disease. He was just 29 years old and at the height of Hollywood fame, a year after the release of the blockbuster Back to the Future III. This week, documentary <a href="https://www.imdb.com/title/tt19853258/">Still: A Michael J. Fox Movie</a> will be released. It features interviews with Fox, his friends, family and experts. Parkinson’s is a debilitating neurological disease characterised by <a href="https://www.mayoclinic.org/diseases-conditions/parkinsons-disease/symptoms-causes/syc-20376055">motor symptoms</a> including slow movement, body tremors, muscle stiffness, and reduced balance. Fox has already <a href="https://www.cbsnews.com/video/michael-j-fox-on-parkinsons-and-maintaining-optimism">broken</a> his arms, elbows, face and hand from multiple falls. It is not genetic, has no specific test and cannot be accurately diagnosed before motor symptoms appear. Its cause is still <a href="https://www.apdaparkinson.org/what-is-parkinsons/causes/">unknown</a>, although Fox is among those who thinks <a href="https://www.cbsnews.com/video/michael-j-fox-on-parkinsons-and-maintaining-optimism">chemical exposure may play a central role</a>, speculating that “genetics loads the gun and environment pulls the trigger”. In research published today in <a href="https://pubs.acs.org/doi/10.1021/acscentsci.2c01468">ACS Central Science</a>, we built an artificial intelligence (AI) tool that can predict Parkinson’s disease with up to 96% accuracy and up to 15 years before a clinical diagnosis based on the analysis of chemicals in blood. While this AI tool showed promise for accurate early diagnosis, it also revealed chemicals that were strongly linked to a correct prediction. <h2>More common than ever</h2> Parkinson’s is the world’s <a href="https://www.who.int/news-room/fact-sheets/detail/parkinson-disease">fastest growing neurological disease</a> with <a href="https://shakeitup.org.au/understanding-parkinsons/">38 Australians</a>diagnosed every day. For people over 50, the chance of developing Parkinson’s is <a href="https://www.parkinsonsact.org.au/statistics-about-parkinsons/">higher than many cancers</a> including breast, colorectal, ovarian and pancreatic cancer. Symptoms such as <a href="https://www.apdaparkinson.org/what-is-parkinsons/symptoms/#nonmotor">depression, loss of smell and sleep problems</a> can predate clinical movement or cognitive symptoms by decades. However, the prevalence of such symptoms in many other medical conditions means early signs of Parkinson’s disease can be overlooked and the condition may be mismanaged, contributing to increased hospitalisation rates and ineffective treatment strategies. <h2>Our research</h2> At UNSW we collaborated with experts from Boston University to build an AI tool that can analyse mass spectrometry datasets (a <a href="https://www.sciencedirect.com/topics/neuroscience/mass-spectrometry">technique</a> that detects chemicals) from blood samples. For this study, we looked at the Spanish <a href="https://epic.iarc.fr/">European Prospective Investigation into Cancer and Nutrition</a> (EPIC) study which involved over 41,000 participants. About 90 of them developed Parkinson’s within 15 years. To train the AI model we used a <a href="https://www.nature.com/articles/s41531-021-00216-4">subset of data</a> consisting of a random selection of 39 participants who later developed Parkinson’s. They were matched to 39 control participants who did not. The AI tool was given blood data from participants, all of whom were healthy at the time of blood donation. This meant the blood could provide early signs of the disease. Drawing on blood data from the EPIC study, the AI tool was then used to conduct 100 “experiments” and we assessed the accuracy of 100 different models for predicting Parkinson’s. Overall, AI could detect Parkinson’s disease with up to 96% accuracy. The AI tool was also used to help us identify which chemicals or metabolites were likely linked to those who later developed the disease. <h2>Key metabolites</h2> Metabolites are chemicals produced or used as the body digests and breaks down things like food, drugs, and other substances from environmental exposure. Our bodies can contain thousands of metabolites and their concentrations can differ significantly between healthy people and those affected by disease. Our research identified a chemical, likely a triterpenoid, as a key metabolite that could prevent Parkinson’s disease. It was found the abundance of triterpenoid was lower in the blood of those who developed Parkinson’s compared to those who did not. Triterpenoids are known <a href="https://www.sciencedirect.com/topics/neuroscience/neuroprotection">neuroprotectants</a> that can regulate <a href="https://onlinelibrary.wiley.com/doi/10.1002/ana.10483">oxidative stress</a> – a leading factor implicated in Parkinson’s disease – and prevent cell death in the brain. Many foods such as <a href="https://link.springer.com/article/10.1007/s11101-012-9241-9#Sec3">apples and tomatoes</a> are rich sources of triterpenoids. A synthetic chemical (a <a href="https://www.cdc.gov/biomonitoring/PFAS_FactSheet.html">polyfluorinated alkyl substance</a>) was also linked as something that might increase the risk of the disease. This chemical was found in higher abundances in those who later developed Parkinson’s. More research using different methods and looking at larger populations is needed to further validate these results. <h2>A high financial and personal burden</h2> Every year in Australia, the average person with Parkinson’s spends over <a href="https://www.hindawi.com/journals/pd/2017/5932675/">A$14,000</a>in out-of-pocket medical costs. The burden of living with the disease can be intolerable. Fox acknowledges the disease can be a “nightmare” and a “living hell”, but he has also found that “<a href="https://www.cbsnews.com/video/michael-j-fox-on-parkinsons-and-maintaining-optimism">with gratitude, optimism is sustainable</a>”. As researchers, we find hope in the potential use of AI technologies to improve patient quality of life and reduce health-care costs by accurately detecting diseases early. We are excited for the research community to try our AI tool, which is <a href="https://github.com/CRANK-MS/CRANK-MS">publicly available</a>. This research was performed with Mr Chonghua Xue and A/Prof Vijaya Kolachalama (Boston University).
