title: A case of progressive hemichorea responsive to high-dose reserpine.
abstract: A 74-year-old woman developed a slowly progressive hemichorea starting 3 weeks after discontinuation of low-dose amitriptyline and perphenazine. The duration of neuroleptic exposure was 3 months. The chorea was initially well controlled on 5.25 mg/day of reserpine, but after 21 months, required 2.0 mg/day. No complications of reserpine occurred.
