The interaction between the growing cases of eating disorders and schizophrenia spectrum disorders is a complex area that has received little attention. Its study raises conceptual and methodological questions in both areas of psychiatry with the aim of timely diagnosis and treatment of patients with anorexia syndrome.The aim of the work is to discuss the possible differences in the outcomes of inpatient treatment of people with eating disorders, depending on the true nosological affiliation of the anorexia syndrome and, accordingly, associated with different times of psychopharmacological interventions. The authors describe two clinical cases of patients with deviant eating behavior, demonstrating the exceptional importance of an integrative assessment of the anorexia syndrome in the psychiatrist’s work (on the example of using the method of differential diagnosis of eating disorders and schizophrenia in psychiatric hospitals).
