Tardive dyskinesia and anticholinergic drugs

Abstract

The evidence from the literature does not support the notion that psychotropic drugs with central anticholinergic properties (antiparkinsonian drugs, neuroleptics, antidepressants) constitute a risk factor in tardive dyskinesia. Antiparkinsonian drugs tend to produce reversible increases in the severity of dyskinetic movements and can be used as pharmacological probes in the assessment of neuroleptic-induced movement disorders.
