title: Risperidone treatment of neuroleptic-induced tardive extrapyramidal symptoms.
abstract: Tardive extrapyramidal symptoms (EPS) induced by neuroleptic treatment, and particularly EPS which persist after withdrawal of the drugs, are clinically serious problems. We describe a patient with four types of tardive and persistent EPS such as dystonia, dyskinesia, choreatic movement and myoclonus, induced by haloperidol. These EPS were remarkably inhibited by 3 mg/day risperidone. This is the first published case demonstrating simultaneous development of these four types of tardive EPS induced by a neuroleptic and then reduced by low-dose risperidone treatment. ( Int J Psych Clin Pract 2000; 4: 241 - 243).
