In a nutshell: 

Exercising regularly in old age may better protect against brain shrinkage than engaging in mental or social activities, according to a new study published in the journal, Neurology®.

Researchers looked at medical records of 638 people from Scotland born in 1936. The participants were given MRI scans at 73 years old. The group gave details about their exercise habits, ranging from moving only in connection with necessary household chores to keeping fit with heavy exercise or participating in competitive sports several times per week. They also reported their participation in social and mentally stimulating activities.

The study found that after three years, people who participated in more physical activity experienced less brain shrinkage than those who exercised minimally.
