The prevalence of tardive dyskinesia (TD) in 70 Nigerian schizophrenics was 37%. Age was related to the presence of TD in males but not in females. Significantly more females had TD in the lower extremities. Comparison of patients with TD and those without revealed no significant differences with regard to the presence of neurological "soft" signs.
