title: Higher levels of serum copper in schizophrenic patients treated with depot neuroleptics.
abstract: The findings of previous research on the status of trace elements in patients with schizophrenia have been controversial. We studied 62 outpatients with a DSM-IV diagnosis of schizophrenia, and compared them with sex- and age-matched healthy controls. Serum copper levels were significantly higher in schizophrenic patients (mean 117.4 microg/dl; S.D. 23.4) than in healthy controls (105.6+/-27.9). Those patients on treatment with depot neuroleptics had higher copper levels. Zinc levels did not differ between patients and healthy controls. Altered levels of trace elements in schizophrenic patients may be a consequence of antipsychotic treatment.
