The authors studied patients with weight loss and vomiting,
distinguishing by means of objective criteria those who had what they feel
is a conversion disorder from those with anorexia nervosa. The group of
patients with conversion disorder were quite different from those with
anorexia nervosa and could be considered as suffering from less pervasive
psychological deficits. Medical and psychotherapeutic intervention must
take into account the differences between these two groups for treatment to
achieve maximal benefit.
