The purpose of this article is to report the prevalence of tardive dyskinesia using strict diagnostic criteria in a large sample of chronic mental patients. The criteria used were those of Villeneuve, and only patients with constant movements were counted. The disorder was significantly (p <.001) less frequent in males (5.8 per cent) than females (10.6 per cent). The study found an overall prevalence of 8.2 per cent in 3140 patients. This figure should represent a minimal prevalence figure since only patients with severe symptoms were included.
