Abstract
Neurologic side effects of antipsychotic drugs in the treatment of major psychiatric disorders are causing great concern. The status of tardive dyskinesia in 13 elderly psychiatric patients at the 5 yr follow-up point is reported. In 11 of 13, tardive dyskinesia persisted. Among these 11 patients, severity was reduced in 2, increased in 2 and unchanged in 7. Only in 2 of the 13 subjects had the tardive dyskinesia disappeared. However, both of these patients were receiving neuroleptic drugs and had parkinsonism, a syndrome that might have masked the dyskinesia. Recommendations are made for prophylaxis and for good clinical judgment in the use of antipsychotic drugs.
