20 Bad Habits That Damage Your Brain

You’re not taking steps to save your mind

There’s no getting around the fact that normal aging brings brain changes that slow cognitive function: Some brain regions shrink, communication between neurons may decrease, blood flow in the brain may lessen, and inflammation could increase, says the National Institute on Aging (NIA). But certain daily habits may accelerate this brain aging—and there is something you can do about that. While researchers haven’t confirmed a specific “prescription” for ideal cognitive health, says Marie A. Bernard, MD, deputy director of the NIA, a growing body of research—including a 2017 report from the National Academies of Sciences, Engineering, and Medicine—suggests practices that are healthy in general may also be beneficial for cognition.
