[Schizophrenia, schizophrenia-like disorders and delusional disorders in patients with anorexia nervosa: literature review and report of 3 cases].

The authors present the review of literature concerning schizophrenia, schizophrenia type and delusional disorders in patients with a lifetime diagnosis of anorexia nervosa (AN). The authors describe also 3 patients (2 cases of paranoid schizophrenia and 1 case of catatonic syndrome). The clinical features in all patients are discussed. In 1 patient the catatonic symptoms occurred within the context of AN, (perhaps due to metabolic disturbances) and in 2 other cases the psychotic features occurred after recovery from AN. The authors discuss the occurrence of psychotic features in AN, and the possible function of starvation and metabolic disturbances in their aetiology.
