Abstract
Wilson's disease is an autosomal recessive disease of abnormal copper metabolism. Psychosis is a rare manifestation of Wilson's disease. Few cases of misdiagnosing Wilson's disease as an etiology of psychosis were reported in the literature. We report a case of a 42-year-old patient, who was diagnosed with a schizoaffective disorder and treated with antipsychotics for 3 years with no significant improvement. On reevaluation, we the patient was diagnosed to have Wilson's disease. The patient's symptoms improved significantly with chelation therapy.
