Want To Lower Your Dementia Risk? Get These 3 Factors Under Control.

Thursday, April 18, 2024

Dementia is extremely common. According to a 2022 study, a startling 10% of adults in the United States over the age of 65 have dementia, and another 22% have mild cognitive impairment. And dementia risk only increases as we get older: Thirty-five percent of people over the age of 90 are living with dementia.The condition isn’t entirely preventable — age, genetics, and environmental influences can all play a role. But some lifestyle-related risk factors are within your control. Below, neurologists share the three most important risk factors to address if you want to prevent dementia, and the best steps you can start taking today.Risk factor #1: Not enough exerciseWe all know that the benefits of getting the recommended 150 minutes of exercise per week extend far beyond maintaining or losing weight. And one of those benefits is lowering your dementia risk.”Obesity, hypertension and diabetes are associated with up to 50% of dementia cases,” Dr. Alvaro Pascual-Leone, a professor of neurology at Harvard Medical School, told HuffPost. “It follows that improving risk factors, such as [sedentary] lifestyles that contribute to developing those conditions, could significantly decrease dementia rates.”In addition to helping to control obesity, hypertension and diabetes, Pascual-Leone said, physical exercise might also help promote the formation of new brain cells. “This improves the efficacy of the mechanisms of brain plasticity, which are critical for the acquisition of new skills and the formation of memories,” he said.Don’t know where to begin with exercise? Pascual-Leone said that if you haven’t exercised in a while, you should talk to your doctor or physical therapist to help you get a safe start. “Aerobic, strength training and mind-body exercises can help sharpen your mind,” he said. “Aim for a combination of aerobic exercise such as walking or cycling, strength training with weights or resistance bands, and mind-body exercises such as yoga or tai chi, which can calm your mind. Work up to at least 30 minutes of exercise per day, five days per week.”andreswd via Getty ImagesSocial interaction and exercise are both crucial for curbing dementia risk.Risk factor #2: Not enough social interactionLoneliness is highly correlated with depression, alcohol misuse and sleep problems. As it turns out, it’s also a risk factor for dementia. “Having limited social engagement and interaction is linked to higher dementia risk,” Dr. Smita Patel, a physician and neuroscientist, told HuffPost. Beyond protecting your brain, Patel noted that increased social interaction can help you live longer, too. “Your overall survival rate increases by 50% if you have strong social relationships. More than 80% of centenarians communicate with a friend or family member daily.”“Interactions with families, friends, and neighbors make us who we are,” Pascual-Leone said. “These moments not only make us feel good, but they also improve our brain function and overall health. Studies show that feeling lonely can be as harmful for your health as better-known risk factors such as daily smoking, or serious health conditions like diabetes.”If you’re worried you don’t get enough social interaction, Pascual-Leone said there are some steps you can take ASAP.“Start by identifying five close friends, and connect with each person at least once a week,” he said. “This can mean calling them on the phone or meeting for tea or coffee. Next, ask yourself if you feel lonely. If the answer is yes, talk with your family and closest friends about what you can do together. You can also think about joining a club, class, or group in your area made up of people who share your interests.”Risk factor #3: Not enough sleep“Inadequate sleep, particularly sleeping less than five to six hours per night, is associated with an increased risk of developing dementia later in life,” Patel said. And unfortunately, insomnia only becomes more common as we age.If you’re struggling to get more than five hours of sleep per night, Pascual-Leone suggested a few steps to take. “You can do this by limiting alcohol, avoiding large meals and drinks two hours before bedtime, keeping your room nice and cool (between 60 and 68 degrees Fahrenheit), avoiding exposure to phones, laptops and TVs two hours before bed, and using a white noise app or machine,” he said.These aren’t the only lifestyle-related risk factors for dementia, but getting them under control can make a significant difference in lowering your risk. “There is currently is no cure for dementia,” Pascual-Leone said. “But there are several lifestyle and activity behaviors everyone can put into action to manage their overall brain health.”In other words, when it comes to dementia, prevention is the best medicine.

A Recipe for Avoiding 15 Million Deaths a Year and Climate Disaster Is Fixing Food, Scientists Say

Scientists are presenting new evidence that the worst effects of climate change can’t be avoided without a major transformation of food systems

Their conclusion: Without substantial changes to the food system, the worst effects of climate change will be unavoidable, even if humans successfully switch to cleaner energy.“If we do not transition away from the unsustainable food path we’re on today, we will fail on the climate agenda. We will fail on the biodiversity agenda. We will fail on food security. We’ll fail on so many pathways,” said study co-author Johan Rockström, who leads the Potsdam Institute for Climate Impact Research.The commission's first report in 2019 was regarded as a “really monumental landmark study” for its willingness to take food system reform seriously while factoring in human and environmental health, said Adam Shriver, director of wellness and nutrition at the Harkin Institute for Public Policy and Citizen Engagement. Key points from the latest report: A ‘planetary health diet’ could avert 15 million deaths every year The first EAT-Lancet report proposed a “planetary health diet” centered on grains, fruits, vegetables, nuts and legumes. The update maintains that to improve their health while also reducing global warming, it's a good idea for people to eat one serving each of animal protein and dairy per day while limiting red meat to about once a week. This particularly applies to people in developed nations who disproportionately contribute to climate change and have more choices about the foods they eat.The dietary recommendations were based on data about risks of preventable diseases like Type 2 diabetes and cardiovascular disease, not environmental criteria. Human and planetary health happen to be in alignment, the researchers said.Rockström said it may seem “boring” for an analysis to reach the same conclusion six years later, but he finds this reassuring because food science is a rapidly moving field with many big studies and improving analytics.Food is one of the most deeply personal choices a person can make, and “the health component touches everyone’s heart,” Rockström said. While tackling global challenges is complicated, what individuals can do is relatively straightforward, like reducing meat consumption without eliminating it altogether.“People associate what they eat with identity” and strict diets can scare people off, but even small changes help, said Emily Cassidy, a research associate with climate science nonprofit Project Drawdown. She wasn’t involved with the research. Our food choices could push the planet past a tipping point The researchers looked beyond climate change and greenhouse gas emissions to factors including biodiversity, land use, water quality and agricultural pollution — and concluded that food systems are the biggest culprit in pushing Earth to the brink of thresholds for a livable planet.The report is “super comprehensive” in its scope, said Kathleen Merrigan, a professor of food systems at Arizona State University who also wasn’t involved with the research. It goes deep enough to show how farming and labor practices, consumption habits and other aspects of food production are interconnected — and could be changed, she said. “It’s like we’ve had this slow awakening to the role of food” in discussions about planetary existence, Merrigan said. Changing worldwide diets alone could lead to a 15% reduction in greenhouse gas emissions from agriculture, because the production of meat, particularly red meat, requires releasing a lot of planet-warming gases, researchers concluded. Increased crop productivity, reductions in food waste and other improvements could bump that to 20%, the report said.Cassidy said that if the populations of high- and middle-income countries were to limit beef and lamb consumption to about one serving a week, as recommended in this latest EAT-Lancet report, they could reduce emissions equal to Russia's annual emissions total. Incorporating justice in an unequal world Meanwhile, the report concludes that nearly half the world's population is being denied adequate food, a healthy environment or decent work in the food system. Ethnic minorities, Indigenous peoples, women and children and people in conflict zones all face specific risks to their human rights and access to food.With United Nations climate talks around the corner in November, Rockström and other researchers hope leaders in countries around the world will incorporate scientific perspectives about the food system into their national policies. To do otherwise “takes us in a direction that makes us more and more fragile,” he said.“I mean both in terms of supply of food, but also in terms of health and in terms of stability of our environments,” Rockström said. “And this is a recipe to make societies weaker and weaker.”The Associated Press’ climate and environmental coverage receives financial support from multiple private foundations.

Study Shows the World Is Far More Ablaze Now With Damaging Fires Than in the 1980s

A new study shows that the world's most damaging wildfires are happening four times more often now compared to the 1980s

WASHINGTON (AP) — Earth’s nastiest and costliest wildfires are blazing four times more often now than they did in the 1980s because of human-caused climate change and people moving closer to wildlands, a new study found.A study in the journal Science looks at global wildfires, not by acres burned which is the most common measuring stick, but by the harder to calculate economic and human damage they cause. The study concluded there has been a “climate-linked escalation of societally disastrous wildfires.”A team of Australian, American and German fire scientists calculated the 200 most damaging fires since 1980 based on the percentage of damage to the country's Gross Domestic Product at the time, taking inflation into account. The frequency of these events has increased about 4.4 times from 1980 to 2023, said study lead author Calum Cunningham, a pyrogeographer at the Fire Centre at the University of Tasmania in Australia. “It shows beyond a shadow of a doubt that we do have a major wildfire crisis on our hands,” Cunningham said.About 43% of the 200 most damaging fires occurred in the last 10 years of the study. In the 1980s, the globe averaged two of these catastrophic fires a year and a few times hit four a year. From 2014 to 2023, the world averaged nearly nine a year, including 13 in 2021. It noted that the count of these devastating infernos sharply increased in 2015, which “coincided with increasingly extreme climatic conditions.” Though the study date ended in 2023, the last two years have been even more extreme, Cunningham said.Cunningham said often researchers look at how many acres a fire burns as a measuring stick, but he called that flawed because it really doesn't show the effect on people, with area not mattering as much as economics and lives. Hawaii's Lahaina fire wasn't big, but it burned a lot of buildings and killed a lot of people so it was more meaningful than one in sparsely populated regions, he said.“We need to be targeting the fires that matter. And those are the fires that cause major ecological destruction because they’re burning too intensely,” Cunningham said. But economic data is difficult to get with many countries keeping that information private, preventing global trends and totals from being calculated. So Cunningham and colleagues were able to get more than 40 years of global economic date from insurance giant Munich Re and then combine it with the public database from International Disaster Database, which isn't as complete but is collected by the Catholic University of Louvain in Belgium.The study looked at “fire weather” which is hot, dry and windy conditions that make extreme fires more likely and more dangerous and found that those conditions are increasing, creating a connection to the burning of coal, oil and natural gas.“We’ve firstly got that connection that all the disasters by and large occurred during extreme weather. We’ve also got a strong trend of those conditions becoming more common as a result of climate change. That’s indisputable,” Cunningham said. “So that’s a line of evidence there to say that climate change is having a significant effect on at least creating the conditions that are suitable for a major fire disaster.”If there was no human-caused climate change, the world would still have devastating fires, but not as many, he said: “We’re loading the dice in a sense by increasing temperatures.”There are other factors. People are moving closer to fire-prone areas, called the wildland-urban interface, Cunningham said. And society is not getting a handle on dead foliage that becomes fuel, he said. But those factors are harder to quantify compared to climate change, he said."This is an innovative study in terms of the data sources employed, and it mostly confirms common sense expectations: fires causing major fatalities and economic damage tend to be those in densely populated areas and to occur during the extreme fire weather conditions that are becoming more common due to climate change," said Jacob Bendix, a geography and environment professor at Syracuse University who studies fires, but wasn't part of this research team.Not only does the study makes sense, but it's a bad sign for the future, said Mike Flannigan, a fire researcher at Thompson Rivers University in Canada. Flannigan, who wasn't part of research, said: "As the frequency and intensity of extreme fire weather and drought increases the likelihood of disastrous fires increases so we need to do more to be better prepared."The Associated Press’ climate and environmental coverage receives financial support from multiple private foundations.

Senior Tories dismayed at Badenoch’s ‘catastrophic’ vow to repeal Climate Change Act

The former prime minister Theresa May has condemned a promise made by Kemi Badenoch to repeal the Climate Change Act if the Tories win the next general election, calling the plans a “catastrophic mistake”.She joined other leading Tories, business groups, scientists and the Church of England in attacking the Conservative leader’s announcement, which would remove the requirement for governments to set “carbon budgets” laying out how far greenhouse gas emissions will be cut every five years, up to 2050.May called it a “retrograde” step which upended 17 years of consensus between the UK’s main political parties and the scientific community. She continued: “To row back now would be a catastrophic mistake for while that consensus is being tested, the science remains the same. We owe it to our children and grandchildren to ensure we protect the planet for their futures and that means giving business the reassurance it needs to find the solutions for the very grave challenges we face.”Green Tories have been increasingly concerned at Badenoch’s move to position the Tories closer to the Reform party, whose senior leaders deny climate science, on energy and net zero policy.Repealing the 2008 Climate Change Act and cancellation of the target of reaching net zero greenhouse gas emissions by 2050 would remove obligations to cut carbon and dismantle the cornerstone of climate policy.Under the act, which was passed by Labour with the support of David Cameron’s Conservative party, with only five rebels voting against, ministers must set five-yearly limits on the UK’s future emissions and bring in policies to meet them. It was the first such legislation in the world, but scores of other countries have since followed suit.Alok Sharma, the Tory former minister and peer who was president of the Cop26 UN climate summit in Glasgow in 2021, told the Guardian: “Thanks to the strong and consistent commitment of the previous Conservative government to climate action and net zero, the UK attracted many tens of billions of pounds of private sector investment and accompanying jobs. This is a story of British innovation, economic growth, skilled jobs and global leadership – not just a matter of environmental stewardship.”He warned that Badenoch risked not just alienating allies on the world stage, but discouraging voters. “Turning our back on this progress now risks future investment and jobs into our country, as well as our international standing,” he said. “The path to a prosperous, secure, and electable future for the Conservative party lies in building on our achievements, not abandoning them.”Lord Deben, who served as environment secretary under Margaret Thatcher and John Major, said none of Badenoch’s predecessors would have countenanced such a move. “This is not what Margaret Thatcher would have done,” he told the Guardian. “She understood this. If you want de-industrialisation of Britain, then [repealing the Climate Change Act] is the right way to go about it.”Business leaders also warned of serious economic damage. Rain Newton-Smith, the chief executive of the CBI, the UK’s biggest business association, said: “The scientific reality of climate change makes action from both government and business imperative. Scrapping the Climate Change Act would be a backwards step in achieving our shared objectives of reaching economic growth, boosting energy security, protecting our environment and making life healthier for future generations.”She said investment had been stimulated, not stifled as Badenoch suggested, by the legislation. “The Climate Act has been the bedrock for investment flowing into the UK and shows that decarbonisation and economic growth are not a zero-sum game. Businesses delivering the energy transition added £83bn to the economy last year alone, providing high-paying jobs to almost a million people across the UK,” she said. “Ripping up the framework that’s given investors confidence that the UK is serious about sustainable growth through a low-carbon future would damage our economy.”If Badenoch were to repeal the Climate Change Act, Britain’s exports could be hit under the EU’s green tariffs. The EU’s carbon border adjustment mechanism, now in its trial stages, imposes levies on companies from countries that are not judged to have an adequate price on carbon. The measure, intended to prevent other countries from undercutting climate rules, could add crippling costs to the UK’s industrial exports to its biggest trading partner.Civil society also rallied to reject Badenoch’s plans. Both the Church of England and the Catholic church spoke out, with Graham Usher, the bishop of Norwich, lead for environmental affairs for the Church of England, saying: “For Britain, the Climate Change Act reflects the best of who we are as a country: a nation that cares for creation, protects the vulnerable and builds hope for future generations. To weaken it now would be to turn our back on that calling and on the values we share as a nation. That is why the Church of England has committed to strive for net zero by 2030, because caring for God’s creation is not optional; it is essential if we are to safeguard the Earth for those who come after us.”Bishop John Arnold, the Catholic lead for the the environment, referred to the speech by Pope Leo XIV on Wednesday, criticising climate sceptics. “Pope Leo XIV yesterday inspired us to work with unity and togetherness on the challenges facing our common home … More than ever, we need to work together, to think of future generations and take urgent action if we are to truly respond to the scale of this climate crisis. A crisis which affects those who are poorest and most vulnerable and have done least to cause it.”

Tories pledge to scrap landmark climate legislation

Conservative leader Kemi Badenoch says her party would axe legally binding targets to cut emissions.

The Conservatives have pledged to scrap the UK's landmark climate change legislation and replace it with a strategy for "cheap and reliable" energy.The Climate Change Act 2008, which put targets for cutting emissions into law, was introduced by the last Labour government and strengthened under Tory PM Theresa May.Tory leader Kemi Badenoch said her party wanted to leave "a cleaner environment for our children" but argued "Labour's laws tied us in red tape, loaded us with costs, and did nothing to cut global emissions".Environmental groups said the move would be an act of "national self-harm", while Labour said it would be "an economic disaster and a total betrayal of future generations".The 2008 act, which was passed when current Energy Secretary Ed Miliband was in the same role in Gordon Brown's government, committed the UK to cutting carbon emissions by 80% by 2050. In 2019, under May's premiership, this legally binding target was updated to reaching net zero by 2050 - meaning the UK must cut carbon emissions until it removes as much as it produces.At that time the legislation passed through Parliament with the support of all major parties.However, the political consensus on net zero has since fragmented.Badenoch has previously said the target of net zero by 2050 is "impossible" for the UK to meet and promised to "maximise" extraction of oil and gas from the North Sea.Reform UK has also said it would scrap net zero targets if it wins the next election, blaming the policy for higher energy bills and deindustrialisation in the UK.The UK was the first country to establish a long-term legally binding framework to cut carbon emissions and since the act was passed many other countries have introduced similar legislation.However, the Tories said the act forced ministers "to make decisions to meet arbitrary climate targets, even if they make the British people poorer, destroy jobs, and make our economy weaker".Badenoch said: "We want to leave a cleaner environment for our children, but not by bankrupting the country."Climate change is real. But Labour's laws tied us in red tape, loaded us with costs, and did nothing to cut global emissions. Previous Conservative governments tried to make Labour's climate laws work - they don't."Under my leadership we will scrap those failed targets. Our priority now is growth, cheaper energy, and protecting the natural landscapes we all love."However, Miliband said: "This desperate policy from Kemi Badenoch if ever implemented would be an economic disaster and a total betrayal of future generations."The Conservatives would now scrap a framework that businesses campaigned for in the first place and has ensured tens of billions of pounds of investment in homegrown British energy since it was passed by a Labour government with Conservative support 17 years ago."The Liberal Democrats also criticised the announcement.The party's energy security and net zero spokesperson Pippa Heylings said: "The reality is that investing in renewables is the greatest economic growth opportunity in this century and will protect the planet for future generations."Meanwhile, Richard Benwell, chief executive of the Wildlife and Countryside Link coalition of environmental groups, said: "The real route to lasting security is in homegrown clean power, not burning more fossil fuels."Without binding climate law, ministers will be free to trade away our future - and it is nature and the poorest communities that will pay the price."
