[Treatment of tardive dyskinesia caused by neuroleptics]

There are at least four phenomenologically different types of movement disorders that fall under the rubric of tardive dyskinesia: a) classical TD which is choreatic in speed of movement and stereotypic in pattern, b) tardive akathisia, c) withdrawal emergent syndrome, which presents as true chorea and d) tardive dystonia which presents with dystonic movement and postures. This paper reviews the main treatments of tardive dyskinesia. The drugs utilized have been considered according to their mechanism of action.
