Regular exercise reduces the risk of mental decline
Physically active older adults are less likely to decline mentally, even if they already have brain changes that could put them at higher risk, according to a study in Stroke: Journal of the American Heart Association.
The study involved 638 people ages 65 to 84. As shown by MRI scans, the participants already had developed changes to the underlying circuitry of the brain. Such "white matter changes" can be a warning sign of future mental decline. The study participants were all still living independently.
