Your symptoms may be mild or severe, and may interfere with your performance of many day-to-day tasks.

Generalized dystonia affects most or all of your body. In segmental dystonia, two or more adjacent areas of your body are affected. Some types of dystonia are inherited. Dystonia may be linked to altered communication between nerve cells located in the basal ganglia ? an area of the brain involved in initiating muscle contractions. Dystonia sometimes may be inherited. Researchers also have discovered many genetic changes associated with some inherited forms of dystonia.
