Parkinson's Disease and Dystonia

Dystonia, a sustained contraction of any muscles resulting in the contortion of a body part, usually occurs as a result of abnormal activity in the basal ganglia circuitry of the brain. Limbs can draw inward, for example, and necks or trunks can pull sideways or forward. While a majority of people with dystonia do not necessarily have Parkinson’s, some do experience this symptom, as this is the circuitry characteristically affected by the disease. Take this course to learn more about the nature of dystonia and how it is managed in people with Parkinson’s.
