Prevalence of tardive dyskinesia in private psychiatric inpatients

The authors in a one-week period examined inpatients at a large private psychiatric hospital to determine the prevalence of tardive dyskinesia. This population's characteristics are described and defined as different from those studied previously. Five of 90 patients (5.5%) who received neuroleptic drugs were judged to have tardive dyskinesia. The authors review the literature and discuss their findings.
