ABSTRACT
Stuttering as a side effect of antipsychotics is rare. There are a few case reports of antipsychotic-induced stuttering, namely, chlorpromazine, levomepromazine, trifluoperazine, fluphenazine, olanzapine and clozapine. Risperidone is commonly used as an atypical antipsychotic. It is licensed for both acute and chronic psychosis and mania. There is only one documented case report mentioned on risperidone induced stuttering. One case report of risperidone-induced stuttering is now described. Stuttering is a rare side effect and requires a high index of suspicion for diagnosis. Further study and research to identify the neurophysiological and psychological processes behind adult onset stuttering and identification of the processes involved in risperidone induced stuttering would help our understanding further.

Cases presenting with recurrent confusion, alteration of psychomotor activity, and brief psychosis with good inter-episode recovery have many differing etiologies. Only rarely does one diagnose such cases as cycloid psychosis. Even among budding psychiatrists, there seems to be a lack of awareness of this unique disorder. This may be because the present international diagnostic classification systems, ICD10 and DSM IV, do not recognize it as a separate entity. A high index of suspicion is required to diagnose cycloid psychosis. Awareness and recognizing such cases would be helpful clinically as cycloid psychosis entails a distinct prognosis and may require a specific treatment.
