[Nuclear psychopathology in anorexia nervosa].

Some patients seen for the treatment of an eating disorder do not fulfill criteria for either of the two established disorders (Anorexia Nervosa and Bulimia Nervosa). This large number of patients currently can only be diagnosed as eating disorder not otherwise specified-EDNOS-(in DSM-III-R) or as atypical disorder (in ICD-19). The authors study some proposal of definition and classification of the Eating Disorders chapter for EDNOS and atypical disorders would be far smaller than they are now. Problems associated with the inclusion of weight concern as a necessary and defining criterion (the crucial diagnostic issue) are reviewed.
