Vacation activities are often healthier than everyday habits. Since heart disease and cancer are linked to lifestyle choices people can change, such as poor diet and inactivity, maintaining habits fostered on vacation can improve overall health. These habits include spending more time outdoors, moving more, spending less time online, eating a more varied diet, dining more with others, getting more sleep, and engaging their brain in novel ways.

Physical activity lowers cardiovascular disease risk in part by reducing stress-related activity in the brain, according to a 2024 study.

It's well known that ultra-processed foods are unhealthy. But what if you follow a healthy diet yet also eat some ultra-processed foods? A new study found that this still poses a risk for brain health.

Super-agers are individuals known to maintain peak mental prowess well into their 90s and avoid dementia and Alzheimer's disease. While genetics play a big part in super-agers' cognitive health, adopting healthy lifestyle habits also contributes, and other people might be able to improve their brain health in the same way. These habits include exercising regularly, following a plant-based diet, being social, adopting mentally challenging activities, and getting adequate sleep.

A 2023 study suggests a blood test that looks for a specific biomarker may help identify people with Alzheimer's disease who may benefit from anti-amyloid therapy long before the disease is evident.

A 2024 study suggests that women with polycystic ovary syndrome, a condition stemming from a hormonal imbalance, may face higher risks of cognitive decline at midlife.

There is no cure for Alzheimer's, but medication can help manage the disease. Currently, the main FDA-approved drugs used to treat Alzheimer's are symptomatic drugs, which ease symptoms but don't address the cause of the disease. A new medication has been shown to slow the disease's progression and reverse some of its effects on memory among people with mild Alzheimer's.

A 2024 study found that dietary supplements of galantamine—which is used to treat Alzheimer's symptoms—had an inaccurate amount of the plant extract listed on the label, ranging from less than 2% to 110% of the labeled quantity.

A 2024 randomized controlled trial provides more evidence that taking a daily multivitamin pill offers protection against cognitive decline. The study involved more than 5,000 people (ages 60 or older). Some took a daily multivitamin pill. Others took a placebo. After two years and tests measuring cognitive ability before and after the study period, people who took the vitamins showed slower cognitive decline than people who took a placebo. This was seen consistently in all groups of people.
