Helen emerged into visibility as an object of attention when, as subject in a longitudinal study of normal development from infancy on, she happened to develop Anorexia nervosa (AN) during her adolescence. Sylvia Brody (hereafter SB) has presented two accounts of this research, one from Helen's birth until she was 30 years old (Brody 2002) and the other from her birth through seven years of age (Brody and Axelrad 1978). It is the ®rst report that describes Helen's development of AN when she was an adolescent. This account is very precious to me, because it is the only longitudinal study of the BN-AN syndrome of this scope that I have come across in the eating disorder literature. It thus presents a special opportunity to assess the etiology of this disturbance.
