A group of chronic schizophrenic patients receiving prolonged treatment with neuroleptics was assessed in 1978 at an outpatient clinic to determine the prevalence of Tardive Dyskinesia. Those with TD were reassessed after two and five years with regard to change in TD severity. The Smith scale was used every time and, on the last assessment, the AIMS scale and videotaped interviews were added. Because of the high attrition rate, results, though interesting, cannot be generalized.
