The authors determined the platelet MAO activity of 57 psychotic patients after a placebo period and after 3-65 days of neuroleptic treatment. Platelet MAO activity significantly decreased in both men and women after neuroleptic treatment. The platelet MAO activity of neuroleptic-treated schizophrenic woman was significantly less than that of drug-free schizophrenic women, who did differ from normal women. There were trends in the same direction for the schizophrenic men. Previous studies that reported lower platelet MAO activity in neuroleptic-treated schizophrenic patients than in normal controls may have been influenced by this neuroleptic effect.
