Juvenile-onset dystonia is a form of dystonia, which is a movement disorder characterized by involuntary muscle contractions that cause repetitive movements and/or abnormal postures. The severity and frequency of the movements vary significantly; in some affected people, they may be barely noticeable while in others, the movements are severely disabling and painful. Dystonia can affect just one muscle, a group of muscles or all muscles of the body. Other signs and symptoms of the condition may include a tremor or other neurologic features. In juvenile-onset dystonia, specifically, affected people develop features of the condition between the ages of 13 and 20 years. The underlying cause of juvenile-onset dystonia is poorly understood in most cases. Changes (mutations) in the ACTB gene that are inherited in an autosomal dominant manner have been identified in some families with the condition. Treatment is based on the signs and symptoms present in each person and may include medications, surgery, physical therapy, and other treatments to reduce or eliminate muscle spasms and pain.
