Психопатологические аспекты нервной анорексии

Prevalence of anorexia nervosa among women is 0,5%, whereas mortality related to this disorder amounts to 5–17%. Psychopathological structure of anorexia nervosa implies abnormalities of behavior as well as those of motivation and volition, thinking, perception and appreciation. In addition, mental abnormalities typical for this disorder are evident in regulation of emotions, specific personality traits and self-consciousness. The key psychopathological feature of patients with anorexia nervosa is a lack of cognitive and personal differentiation that calls forth impairments of self-concept and self-image. Anorexia nervosa should be differentiated from depression and schizophrenic spectrum disorders. Its etiology and pathogenesis are related both to hereditary and psychosocial factors. Of great importance are psychoendocrine abnormalities, however their role is still insufficiently elucidated.
