Having a Younger Biological Age Is Linked to Better Brain Health

March 5, 2026

Looking after your longevity might make you smarter. A preliminary study of over 250,000 people found that having a lower biological age compared to chronological age is associated with decreased risk of stroke and better cognitive performance

The longevity movement has changed how we think about aging, as how long you live is no longer about the number of years, but the quality of them, also known as your healthspan.

A key marker of how healthy you’re aging can be biological age, or how quickly your body is aging down to the cellular and tissue levels, which is ideally younger than your actual (chronological) age.

Widening that gap could be crucial to better brain health and lowering your risk of stroke, according to a new preliminary study to be presented at the American Academy of Neurology’s Annual Meeting in April. Athletech News
