Eight patients with dystonia, four with hereditary torsion dystonia and four with acquired dystonia, were treated with carbamazepine in doses ranging from 300 to 1,200 mg/day. Drowsiness was the only side effect and periodic blood cell counts remained normal. All have shown sustained improvement of some manifestations of their illness for periods up to one year.
