Using structural MRIs, Scottish researchers have found physical activity in older individuals resulted in less brain atrophy and increased gray matter volume. In this study 700 individuals age 70 self-reported their regular activities, then 3 years later MRI tests were performed. These findings held true even after controlling for age, sex, health, and intelligence.
