The authors found a high prevalence--43.4% of tardive dyskinesia in a
sample of psychiatric outpatients, a population previously thought to be at
nominal risk for development of this syndrome. There was no significant
relationship between the presence of dyskinesia and age, sex, years of
neuroleptic use, or various organic factors. The effects of dentures and of
drug combinations are discussed, and it is noted that structured scales of
dyskinesia and videotope recordings are important tools in diagnosing and
following the course of dyskinesia.Abstract Teaser
