Scientists scan brains to see which exercise slows brain disease

This study aimed to understand how two types of exercise—balance training and aerobic training—affect the brain in people with degenerative cerebellar diseases like spinocerebellar ataxia. Researchers used brain scans to see if one type of exercise caused more beneficial changes in the cerebellum, the part of the brain affected by the disease. The goal was to gather knowledge to help design better exercise programs that might slow disease progression.
