Abstract

The prevalence of dystonia was studied in 125 veterans on chronic antipsychotic therapy using a detailed and systematic examination. Twenty-seven out of 125 had dystonic manifestations. The most common areas involved were hands and jaw. There was no relation between the presence or absence of dystonia, and duration of neuroleptic therapy. There was a tendency for tardive akathisia to occur more frequently in patients with dystonia than in those without it (Fisher's exact probability test, p = 0.0656). Tardive dystonia in its milder forms may be more common than currently believed.
