In dystonia, your muscles contract involuntarily — causing uncontrollable repetitive or twisting movements of the affected body part. Your symptoms may be mild or severe, and may interfere with your performance of many day-to-day tasks.
Doctors divide dystonia into categories including generalized, focal, segmental and other less common categories. In focal dystonia, the most common category, one part of your body is affected. 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.
Medications can sometimes improve dystonia symptoms, but inconsistently. In some more-severe cases, surgery may be used to disable or regulate certain brain regions or nerves.
