Regular exercise during midlife makes brains functionally younger.
That’s the bracing conclusion of a new study of 130 inactive men and women, most in their 40s. Some began a simple, aerobic exercise program. Others didn’t.
At the end of a year, the exercisers’ brains appeared more youthful on scans than they had been at the start. The brains of the others looked slightly older than before.
