title: Anorexia Nervosa in twins: case report and review.
abstract: The cases of a pair of monozygotic female twins simultaneously concordant for anorexia nervosa area reported. About half of the previously reported cases of anorexia nervosa in twins are concordant; however, interpretation of the clinical data reviewed is difficult because diagnostic criteria are not always clear. Clinical parallels between anorexia nervosa and folie à deux are discussed.
