Apparently, yes. I read an article in YorkU Spring 2014 about how a York Research team collaborated with a retired professional ballet dancer to see if learning to dance or learning a specific dance routine can improve motor control in people with this type of disability.
"Parkinson’s diease is a neurological disease and degenerative disorder of the central nervous system which severely inhibits movement, currently affecting more than 100,000 Canadians. The motor symptoms of Parkinson’s result from the loss of dopamine-generating cells in a region of the midbrain; the cause of the cell death is unknown. Early in the course of the disease, the most obvious symptoms are movement-related, including shaking, rigidity, slowness of movement and difficulty with walking and gait. Later, cognitive and behavioural problems may start to arise, with dementia occuring in the advanced stages of the disease. Depression is the most common psychiatric symptom." The researchers are using Magnetic resonance imaging (MRI) equipment to scan the brains of Parkinson’s patients before during, and after learning a dance routine. They’re trying to determine if the brains of Parkinson’s sufferers might navigate new paths around damaged areas.
Let’s cut to the chase: dance seems to help people with Parkinson’s just like singing helps people who stutter. Their research is ongoing but what they have come across so far in itself is incredible. YAY DANCE.
