Book Chapter Description

The transition to the eleventh revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-11) entails significant innovations for the chapter on eating disorders. By merging feeding and eating disorders into a higher-level category, disorders are grouped according to their psychopathology in the sense of a continuum of psychopathological abnormalities between childhood, adolescence, and adulthood. Furthermore, cultural differences in the clinical manifestation of feeding and eating disorders are taken into account. Newly included diagnoses are Avoidant/Restrictive Food Intake Disorder (ARFID) and Binge Eating Disorder. For the diagnosis of Anorexia Nervosa, the weight criterion has been redefined, and the diagnosis "Anorexia Nervosa in Recovery with Normal Body Weight" has been newly added. The criterion of amenorrhea has been removed, and the fear of weight gain (fat phobia) is no longer listed as a sine qua non criterion. For Bulimia Nervosa, the criterion of binge eating has been expanded and the time criterion has been changed to include atypical and development-dependent variations of the clinical picture. The ICD-10 diagnoses "Atypical Bulimia"Nervosa" (F50.3), "Overeating associated with other psychological disturbances" (F50.4), and "Vomiting associated with other psychological disturbances' (F50.5) are missing in the ICD-11. The diagnoses Other Eating Disorders (F50.8) and Unspecified Eating Disorder (F50.9) are accordingly transferred to Other Specified Feeding or Eating Disorders and Unspecified Feeding or Eating Disorder.
