Risperidone Treatment of Tardive Dyskinesia and Dystonia

Article Abstract

Letter to the Editor

Sir: Although more attention has been given to neurolepticinduced tardive dyskinesia, tardive dystonia, characterized by local or general twisting and sustained muscle spasms, is also a longer term complication of typical neuroleptic treatment. Reported here is a Chinese patient whose psychosis and tardive movements, both dyskinetic and dystonic, were effectively treated when low-dose risperidone was added to diazepam and trihexyphenidyl.
