Prevalence of tardive dystonia

Tardive dystonia is a rare late-onset side effect of neuroleptics. This paper presents a prevalence study of 351 inpatients conducted in our hospital. Seven patients (2%) were found to suffer from this condition. The majority were found to be young and had received neuroleptics for a variable number of years before the onset of the dystonia. In general, treatment of this condition is disappointing.
