Psychosis in anorexia nervosa and bulimia.

In a sample of 130 consecutive patients with a lifetime diagnosis of anorexia nervosa and/or bulimia, 17 displayed psychotic symptoms. In 16 patients, these symptoms appeared attributable to major affective disorder or schizo-affective disorder, while in one, they appeared to represent factitious psychosis. No cases of schizophrenia or organic psychosis were identified.
