Amisulpride-induced tardive dyskinesia.

Tardive dyskinesia (TD) is a movement disorder that develops during the course of long-term treatment with neuroleptic agents and is characterized primarily by choreiform and athetotic movements. We report the case of a 34-year-old man suffering from schizophrenia, disorganized type. He received amisulpride (400 mg daily) and the result was much improvement. 20 months later, he was presented with TD, which resolved almost completely after change of treatment to 1200 mg quetiapine without any relapsing. To our knowledge, his is the first case report in the literature of tardive dyskinesia induced by amisulpride.
