Chediak focuses on the delusional relationship between the patient and her body in describing the symptom complex of anorexia nervosa. The rapprochement crisis with its struggle surrounding separation-individuation could lead to the psychopathology of anorexia nervosa.

In the treatment of anorexia nervosa it is fundamental to recognize the regressive re-enactment of the separation-individuation crisis during adolescence, with the patient's fear and sense of helplessness vis-à-vis the intensity of the drives. Wishes for fusion with the mother promote distortions of body image and fear of self-dissolution. The physiological dysfunctions are unavoidable consequences of the primary psychological disorder.
