A new study has shown that speaking multiple languages can slow down brain aging: for bilingual people, the brain appears up to 6 years younger, while for those who speak four languages, it can look up to 13 years younger. This effect is even stronger if language learning begins early and proficiency is high.
Scientists have demonstrated that miniature brain models grown from the cells of patients with Alzheimer's disease can help predict individual responses to treatment and identify new disease biomarkers. This approach paves the way for more precise and personalized therapies.
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.
Scientists have discovered a molecule produced by certain cancer cells that helps the brain clear out harmful proteins associated with Alzheimer's disease. This finding could lead to new approaches in the prevention of neurodegenerative disorders.
A new Swedish study has found that consuming full-fat dairy products, such as cheese and cream, is associated with a reduced risk of dementia, especially among people without a specific genetic predisposition.
