we examined 423 chronic psychiatric inpatients who had a history of at least three months total cumulative neuroleptic for tardive dyskinesia(TD). In this study, we used both structured scales of dyskinesia and videotape recording. Demographic clinical, and drug history data were collected to assess whether any of these factors was significantly associated with the presence of TD. Female sex, duration of hospitalization, length of neuroleptic treatment, and exposure to antiparkinsonian agents also were related to increased risk. However there was no significant relationship between the presence of TD and other factors including psychiatric diagnosis, daily dosage of neuroleptics, or history of alcohol, smoking, electroconvulsive therapy, head trauma. Interestingly, the history of tricyclic antidepressant medication was associated with decreased prevalence. Further work is needed to perform well-controlled prospective study.
