Olanzapine has been used in various movement disorders: choreic syndromes [Huntington's disease (HD), hemichorea] (1,4,5,6,7), tardive dystonia (8,9,10), tardive dyskinesia (9,11,12), hemiballismus (13), dystonia (14,15), and essential tremor (16,17).
Patient distribution was as follows: Seven patients had chorea due to HD, 1 had tardive dystonia, 1 had oromandibular dystonia (OMD), 1 had post-ischemic hemidystonia, 1 had hemiballismus, and 1 patient had post-traumatic rubral tremor.
