How do they occur: brain atrophy, a worst case scenario. Possible determinants of brain atrophy with age: age/pathology/diet/exercise, brain structure< > brain function. If you have heart disease, increased atrophy. But with exercise, you can preserve with atrophy. Lifelong exercise training increases cortical thickness across much of the brain. The more exercise you do, the better it is. Exercise over one year (65-70 years older) improved atrophy. Associated with improved cognitive functions and member. 6 months through cardiac rehab program, brain gets thicker.
