We don’t just lose muscle over time — our brains can atrophy, too. More specifically, your brain's cognitive reserve — its ability to withstand neurological damage due to aging and other factors without showing visible signs of slowing or memory loss — diminishes through the years. That can make it more difficult to perform mental tasks. But just as weight workouts add lean muscle to your body and help you retain more muscle in your later years, researchers now believe that following a brain-healthy lifestyle and performing regular, targeted brain exercises can also increase your brain's cognitive reserve.
