Family therapy for identical twins with anorexia nervosa

The rarity of identical twins with anorexia nervosa (AN) makes formulating an effective treatment approach for this subset of individuals quite difficult. Clinicians may be applying treatment strategies that have been designed for individuals with an eating disorder. However, these approaches might have to be modified for the treatment of identical twins. The few available case studies have not discussed the challenges a clinician faces when treating identical twins with AN. In this report we describe the presentation of the case of adolescent monozygotic twins who were simultaneously concordant for AN. We discuss their unique presentation and our approach to their treatment.
