Exercise May Slow Brain Aging and Cognitive Decline

High physical activity levels may help preserve brain volume and cognitive function, reducing the risk of Alzheimer’s.

Summary

A UT Southwestern study finds that higher cardiorespiratory fitness may slow age-related brain atrophy, preserving cognitive function. The study, which analyzed 172 adults, showed that those with better physical fitness had larger brain volumes and better cognitive performance, especially in areas linked to memory and reasoning.

Key Takeaways

Higher physical activity is linked to less brain shrinkage, particularly in the right superior parietal area.

Larger brain volumes in this area correlate with better cognitive function, including memory and reasoning.

The findings suggest that lifelong exercise may slow brain aging and reduce dementia risks.
