Physical Activity Improves Brain Size

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.
