title: [Risperidone treatment for polydipsia and severe hyponatremia in a schizophrenic patient].
abstract: We report the case of a patient with undifferentiated schizophrenia since 10 years, who presented a polydipsia and severe hyponatremia. This patient responded well to a combination of an atypical antipsychotic (risperidone 4 mg/day) and a behavioral approach based on fluid restriction.
