Predisposition factors in anorexia nervosa

Abstract

Since its first recognition, a number of researchers have endeavored to link anorexia nervosa to underlying pathology. For example, in the past, attempts were made to associate anorexia with such psychiatric disturbances as schizophrenia, anxiety disorders, and obsessive-compulsive and antisocial personality disorders. Most recent efforts have focused on the possible link between anorexia nervosa and affective disorders. This article reviews the literature concerned with investigating psychiatric disturbances and genetic variables hypothesized as predisposing factors in the etiology of anorexia nervosa. Particular emphasis is given to research which discusses the association between anorexia nervosa and depression. Psychopharmacological evidence and family genetics studies are reviewed. Suggestions for future research are also made.
