Another Reason to Exercise

Aaron D. Gitler

Modern medicine has demonstrated the virtues of healthy diet and routine exercise for cardiovascular health, preventing diabetes, and lowering cholesterol. But a role for exercise in combating neurodegenerative diseases is less well understood. On page 690 in this issue, Fryer et al. (1) present compelling evidence suggesting that exercise might have a long-lasting beneficial effect on slowing neurodegenerative disease progression.
