About 3 percent of U.S. adolescents are affected by an eating disorder, but most do not receive treatment for their specific eating condition, according to an NIMH-funded study published online ahead of print March 7, 2011, in the Archives of General Psychiatry.
Women with bulimia nervosa (BN), when compared with healthy women, showed different patterns of brain activity while doing a task that required self-regulation.

Eating disorders, which include anorexia nervosa, bulimia nervosa and binge-eating disorder, are complex and often life-threatening illnesses.
Reviews of the current research on psychosocial and behavioral therapies, or psychotherapies, for children and adolescents found a number of "well established" and "probably efficacious" treatments for many mental disorders. For example, six were "probably efficacious" for anxiety disorders, and two were "well established" for attention deficit hyperactivity disorder (ADHD), according to scientists funded by NIMH and the National Institute on Drug Abuse, divisions of the National Institutes of Health.
