A Case of Risperidone-Induced Stuttering

• Lee HJ

Abstract

Stuttering as a side effect of antipsychotics is rare. There are only 4 reports of neuroleptic-induced stuttering. Most reports of neuroleptic-inducted stuttering involved low-potency drugs that have high intrinsic antimuscarinic activity. Risperidone is high potent drug and often referred to as 'atypical' antipsychotic agent due to fewer extrapyramidal side effects and efficacy on negative symptoms of schizophrenia. We experienced a case of risperidone-induced stuttering in a young male schizophrenic patient, and report this case.
