Lower your dementia risk with these 2 simple routines — you can even choose how hands-on you want to be
Some 22% of adults 65 and older are believed to have trouble with their memory and thinking, also known as mild cognitive impairment (MCI).
Individuals with MCI can perform most everyday activities and generally manage their own care.

An additional 10% of older adults are estimated to have dementia, which is more severe, interfering with daily life and threatening independence.
The number of new dementia cases is projected to double by 2060, primarily due to the aging population.

Now, new Alzheimer's Association research — known as the POINTER study — finds that two special programs can protect against age-related cognitive decline in older adults.
'As the burden of dementia grows worldwide, US POINTER affirms a vital public health message: healthy behavior has a powerful impact on brain health,' said Alzheimer's Association President and CEO Joanne Pike.
4 The two-year POINTER trial evaluated the effectiveness of two 'lifestyle interventions' that emphasized physical activity, nutrition, brain exercises, social engagement and heart health monitoring.

Research has suggested that about 40% of dementia cases could be prevented or delayed by addressing 14 modifiable risk factors — alcohol abuse, smoking, diabetes, obesity, high blood pressure, air pollution, brain injury, physical inactivity, depression, social isolation, hearing loss, lower levels of education, high cholesterol and vision loss.
The two-year POINTER trial evaluated the effectiveness of two 'lifestyle interventions' that emphasized physical activity, nutrition, brain exercises, social engagement and heart health monitoring.
About 2,100 participants between 60 and 79 years old and at high risk of cognitive decline were split into two groups.
With the self-guided lifestyle intervention, participants attended six peer team meetings that encouraged behavioral changes.

The structured lifestyle intervention was more intense, goal-oriented and supportive.
Participants attended 38 peer team meetings over two years and received detailed recommendations for aerobic resistance and stretching exercises.
They were directed to follow the brain-healthy MIND diet and keep their noggin' engaged with memory, attention and speed exercises.
A study clinician often reviewed their health metrics and goals with them.
About 89% of participants completed the final two-year assessment.

Cognitive function scores increased in both groups. The structured lifestyle intervention had better results, protecting the brain for up to two years.
The findings were presented Monday at the Alzheimer's Association International Conference in Toronto and published in the Journal of the American Medical Association (JAMA).
There's no cure for dementia, but treatments and therapies can help manage symptoms and potentially slow disease progression.
4 The MIND diet emphasizes natural, plant-based foods and not processed foods, saturated fats or red meat.

'The positive results of US POINTER encourage us to look at the potential for a combination of a lifestyle program and drug treatment as the next frontier in our fight against cognitive decline and possibly dementia,' Pike said.
The Alzheimer's Association invested nearly $50 million to lead POINTER, with the National Institute on Aging at the National Institutes of Health chipping in for extra research.
The Alzheimer's group plans to spend an additional $40 million over the next four years to track POINTER participants and introduce brain-healthy initiatives across America.
'While not everyone has the same access or ability to adhere to more intensive behavior interventions, even modest changes may protect the brain,' said Laura D. Baker, POINTER principal investigator and Wake Forest University School of Medicine professor.

Staying sharp, healthy hearts and beach-day calm: The week in Well+Being
You're reading our weekly Well+Being newsletter. Sign up here to get it delivered to your inbox every Thursday. This week we're thinking about healthy brains and hearts. The two are so closely linked, and we know what's good for one is often good for the other. We were excited to see some of the strongest evidence to date that you can protect your brain health with exercise, healthy eating, social interaction and brain games. A new study looked at people at risk of developing dementia because of a family history or other factors, and found a 'recipe' of lifestyle changes helped improve their cognitive function. About 45 percent of all dementia cases might be preventable, according to other research, so this is incredible news for anyone (everyone?) who's worried about their memory or brain health as they age. And back to that heart-mind connection. Those very same lifestyle changes that are so good for your brain often help your heart. Cardiologist Eric Topol shared 10 science-based ways to protect your ticker — plus there's an online tool you can use to find out how 'old' your heart is! — and I'm sure our minds would benefit, too. But before that … A mix of exercise, a healthy diet, social engagement and brain games could improve cognitive capabilities in older adults at risk of cognitive decline or dementia, a clinical trial has found. The study, known as U.S. POINTER, is the largest trial to examine how healthy lifestyle behaviors can improve brain health. Its results were published in JAMA and presented at the Alzheimer's Association International Conference on Monday in Toronto. 'If you can modify these and improve them, then it makes sense that you will improve your brain health and you might prevent dementia,' Kristine Yaffe, a professor and the vice chair of the department of psychiatry at the University of California at San Francisco, told our brain health writer, Richard Sima. Learn more about the study and how you can reduce your risk of dementia here. A free, newly developed online calculator reveals your heart's age and your risk of heart disease, according to a large-scale study of heart health published in JAMA Cardiology. Based on the most current equations about risks for cardiovascular disease, the calculator uses answers to a few simple questions about blood pressure, cholesterol status and other common measures of health, to determine your heart's biological age, which can be different from your body's chronological or calendar age. Fitness columnist Gretchen Reynolds writes that the calculator is at the vanguard of 'organ aging' tests, which use a variety of advanced techniques and algorithms to determine whether certain parts of our bodies are aging faster or slower than others. To find out more about organ aging and how to tell if your heart is as young as you are, read our story here. Our guest columnist is Eric Topol, MD, a cardiologist, professor and the executive vice president of Scripps Research in San Diego. He is the author of 'Super Agers: An Evidence-Based Approach to Longevity' and Ground Truths on Substack. While we've seen some major advances in treating heart disease, it remains the leading killer in the United States, even though about 80 percent of cases are considered preventable. Exercise is considered the single most effective medical intervention to protect against atherosclerosis and promote healthy aging. Physical activity lowers inflammation in the body. Evidence has shown that both aerobic and strength training forms of exercise are important. But only 1 in 4 Americans meet the two activity guidelines from the American Heart Association: aerobic exercise of 150 minutes per week of at least moderate physical activity, such as walking, bicycling on level ground, dancing or gardening, and strength training for at least two sessions per week, which typically translates to 60 minutes weekly. For more evidence-based steps Topol recommends you do to stave off heart disease, read the story here. And use our Ask a Doctor form to submit a question, and we may answer it in a future column. Here are a few things that brought us joy this week. Let's keep the conversation going. We want to hear from you! Email us at wellbeing@ Want to know more about 'joy' snacks? Reporter and former neuroscientist Richard Sima explains what they are and how they can make you feel happier. You can also read his advice as a comic.

Using food stamps can help slow down brain decline as you age: study
The federally funded food stamp program is really delivering for brain health, a new study finds. Over 41 million people participated last year in the US Supplemental Nutrition Assistance Program (SNAP), which helps low-income families purchase nutritious food. We've long known that healthy foods — especially those rich in omega-3 fatty acids, antioxidants and vitamins — can support brain function, memory and cognitive performance. A nutritious diet can support brain function, protect against cognitive decline and potentially reduce the risk of neurodegenerative diseases. Kay Abrahams/ – Now, new research reports that older SNAP recipients have a better chance of staving off cognitive decline than their peers who do not partake in the program. 'Research has shown that food insecurity can negatively impact cognitive function, and this is one of the first long-term studies to show that food assistance programs can positively impact cognition,' said Maria C. Carrillo, chief science officer and medical affairs lead for the Alzheimer's Association. The study, out of the University of Georgia, tracked 1,100 people 50 and older who were enrolled in SNAP in 2010 and 1,200 older adults who were eligible for SNAP but did not participate. Researchers interviewed participants every two years between 2010 and 2020 to assess their memory and ability to plan and carry out tasks. Over 41 million people participated last year in the US Supplemental Nutrition Assistance Program (SNAP), which helps low-income families purchase nutritious food. They determined that SNAP participants had a 0.10% slower decline in overall cognitive function, affording them two to three additional years of good brain health in the 10-year study period. 'For someone starting at a healthy cognitive score, this slower decline could delay reaching the threshold for mild cognitive impairment by nearly a decade,' said Linlin Da, lead study author and a Ph.D. candidate in health services research at UGA. People with mild cognitive impairment face a significantly higher risk of developing dementia, a decline in memory, thinking, language, judgment and behavior that is so severe that it interferes with daily life. While all SNAP participants seemed to benefit brain-wise, Da's team noticed that white SNAP recipients exhibited even slower cognitive decline than black and Hispanic participants. The researchers are calling for further exploration into the racial and ethnic disparities in the relationship between SNAP and cognitive health. Their findings were presented Wednesday at the Alzheimer's Association International Conference in Toronto. The study results come weeks after President Trump's 'One Big Beautiful Bill' introduced steep cuts to SNAP, making it harder for people to qualify and decreasing benefits for eligible recipients. SNAP participants averaged about $187 in monthly benefits before the legislation was approved. The program — which dates back to 1939, during the Great Depression — cost about $100 billion in federal funding last year.
