Can dance classes sharpen the mind for Parkinson's patients?

This study tested whether a 12-week program of weekly improvisational dance classes could help improve thinking skills, mood, and the ability to perform daily activities for people with Parkinson's disease. Twenty participants were randomly assigned to either start the dance classes right away or to a waitlist group. Researchers measured changes in memory, problem-solving, anxiety, fatigue, and how well people could manage daily tasks before and after the program.
