Ashkenazi Disorders: Mendelian
Torsion dystonia I is a progressive movement disorder characterized by sustained, twisting muscle spasms. With time, the frequency and duration of these spasms increases, leading to joint contractures and progressive disability. Individuals with torsion dystonia have normal early development and normal intelligence. The underlying mechanism of the disorder is not well understood. There is no cure, but there has been progress in treating dystonia with a variety of medications.
