Antiparkinsonian medication withdrawal in the treatment of tardive dyskinesia: a report of three cases.

Three patients are presented in whom TD either disappeared (2 cases) or improved (one case) after discontinuing antiparkinsonian medication without changing the concurrent neuroleptic treatment. In addition, two of the patients presented some "complications" secondary to the TD in the form of frequent falling, psychosocial impairment and suicidal ruminations. The implications of these findings are discussed in the light of the current literature.
