Phencyclidine-associated psychosis may mimic classic forms of both schizophrenia and affective psychosis. Treatment of phencyclidine-associated psychosis may prove very difficult for some patients. A patient who developed a severe phencyclidine-associated psychosis and failed to respond to high doses of antipsychotics is described. The patient responded dramatically to electroconvulsive therapy.
