Daytime sleepiness may double dementia risk in elderly women

For women in their 80s, experiencing increasing sleepiness during the day over a five-year period is associated with double the risk of developing dementia during that time, according to a study published on March 19, 2025, online in Neurology®, the medical journal of the American Academy of Neurology.

Better heart health slows brain aging and lowers dementia risk, study finds

A JAMA Network Open study finds that better cardiovascular health (CVH) in older adults is linked to lower levels of neurodegenerative biomarkers, particularly neurofilament light chain (NfL). These benefits are consistent across races and especially impactful for individuals carrying Alzheimer's-related genetic risks.
