Advances in diagnosis and treatment of anorexia nervosa and bulimia nervosa.
This paper reviews four areas of research into anorexia nervosa (AN) and bulimia nervosa (BN). First, in terms of diagnosis, the psychological concerns about weight and shape are now addressed in BN, bringing it more in line with the related disorder, anorexia nervosa. Second, studies of psychiatric comorbidity confirm the overlap between eating disorders and depression, obsessive compulsive disorder, substance abuse, and personality disorder. Nevertheless, there are reasons to accept the distinct qualities of each syndrome, and eating disorders are not merely a variant of these other conditions. Third, treatment advances in BN involve mainly cognitive-behavioural or interpersonal psychotherapies and pharmacotherapies primarily with antidepressants. The effect of combining more than one approach is beginning to be addressed. Finally, outcome studies involving people with both AN and BN have shown that the disorders "cross over" and that both conditions have a high rate of relapse. A renewed interest in the treatment of AN is needed.
