Mood, memory, and motor performance and the severity of tardive dyskinesia

This study tested the hypothesis that the features of tardive dyskinesia were associated with motor slowing, memory impairment, and depressive apathy all of which are considered to characterize the so-called subcortical dementias. In a sample of 48 psychiatric patients all fulfilling research criteria for tardive dyskinesia and without other signs of organic illness age-independent correlations were observed between severity of orofacial dyskinesia and measures of memory, motor performance and mood providing some empirical support for the hypothesis.
