Abstract
Anorexia nervosa is one of the most difficult psychiatric disorders to treat. Despite the refinement of treatment techniques, a recent review showed little convincing evidence of improved outcome of anorexia nervosa in the second half of the past century.1 There are few controlled treatment trials for this disorder because (1) the disorder is relatively rare, so that it is difficult to generate an adequate sample size in any one center; (2) patients with anorexia nervosa have a pronounced resistance to treatment and are at best ambivalent toward treatment; and (3) medical complications often require withdrawal from treatment protocols.
