The duration and quality of sleep are directly linked to the risk of developing cardiovascular, neurological, and mental health disorders. Research has shown that spending enough time in key sleep stages, especially during REM sleep, can significantly reduce the likelihood of dementia, heart disease, and other serious conditions. Regular nightly rest lasting 6 to 8 hours is considered an effective preventive measure against illnesses in adults.
A new study has shown that in elderly people with sleep disorders and early signs of dementia, taking high doses of vitamin D is associated with improved cognitive function. This effect was observed only at doses of 5,000 IU per day or higher.
Nearly half of all dementia cases are linked to modifiable risk factors, such as smoking and high blood pressure. Research has shown that healthy habits can delay the onset of symptoms of Alzheimer's disease and vascular dementia.
A pilot study has shown that reducing the daily eating window may not only help older women lose weight, but can also moderately improve their cognitive functions. Larger-scale studies are needed to confirm these findings.
A new study has found that different microglial responses in the brain may explain why some people are more resistant to dementia in Alzheimer's disease. These findings open up new possibilities for developing therapies aimed at supporting the brain's protective microglial functions.
A two-year study found that omega-3 fatty acid supplements did not improve memory or cognitive function in older adults at risk for Alzheimer's disease. Taking fish oil did not slow age-related changes in the brain compared to a placebo.
Studies show that frequent television viewing in middle age is associated with a reduction in the volume of certain brain regions and signs of damage decades later. Engaging in mentally active tasks while sitting has a more positive effect on brain health than passive TV watching.
American scientists have developed an experimental nasal spray that reduces neuroinflammation and restores cognitive function in age-related brain changes. In animal studies, the drug demonstrated improved memory and good tolerability. The next step is clinical trials in humans.
A large-scale study has shown that using hearing aids reduces the risk of developing dementia, especially when the devices are highly effective. High-quality hearing correction provides the greatest protection for the cognitive health of older adults.
Long-term studies have shown that some people over the age of 80 maintain memory and mental sharpness at a level comparable to much younger individuals. Examining their brains and lifestyles helps us understand the mechanisms behind resilience to dementia and may lead to new strategies for preventing age-related cognitive decline.
A new study has shown that among elderly people with a genetic predisposition to Alzheimer's disease, a high intake of meat may be associated with a lower risk of dementia. This highlights the importance of tailoring dietary recommendations to individual genetic profiles.
Just a few minutes of vigorous physical activity each day can significantly reduce the risk of developing serious illnesses, including diabetes, dementia, and heart disease. Even short bursts of activity, such as brisk walking or climbing stairs, provide noticeable health benefits.
Moderate consumption of coffee or tea is associated with a lower risk of dementia and a slower decline in cognitive function with age, according to a large-scale study. The greatest benefit was observed in those who drank 2–3 cups of coffee or 1–2 cups of tea per day.
An international team of researchers has identified three already approved drugs that may be effective for the treatment or prevention of Alzheimer's disease. Large-scale clinical trials are needed to confirm their benefits.
A new study has shown that taking medications against toxoplasmosis and receiving a herpes vaccine are associated with a reduced risk of developing Alzheimer's disease. However, scientists emphasize that these findings require further confirmation.
