The most prevalent psychiatric disorders in the families of patients
with anorexia nervosa are bipolar and unipolar major affective disorder.
The presence of affective disorder, self-induced vomiting, or bulimia in
the patient is not predictive of affective illness in the relatives. Thus
these features do not define genetic heterogeneity within anorexia nervosa.
There may be genetic factors shared between anorexia nervosa and affective
disorders.
