Orofacial dyskinesias and choreiform movements of limbs occur with moderate
frequency among psychiatric patients. Abnormal involuntary movements are
symptoms of a wide variety of neurological and medical disorders. For both
therapeutic and medicolegal reasons, psychiatric patients should be
thoroughly evaluated before being given the diagnosis of tardive
dyskinesia. This review presents the differential diagnosis of disorders
associated with orofacial and appendicular choreiform involuntary
movements. In addition, this paper provides a guide to the clinical and
laboratory evaluation of patients with these symptoms.
