Treating Childhood Psychopathology and Developmental Disabilities
Eating problems or irregularities are common among children and adolescents. When the problems reach the point of being gross disturbances in eating behavior and when accompanied by some form of body image disturbance, we enter the realm of the Eating Disorders (EDs). The current Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR; APA, 2000) distinguishes between three primary ED types: Anorexia Nervosa (AN), Bulimia Nervosa (BN), and Eating Disorder Not Otherwise Specified (EDNOS). The latter refers to cases that meet some but not all the criteria required for the diagnosis of either AN or BN. Binge-Eating Disorder (BED) is a more recently recognized disorder that is technically a variant of the EDNOS category (although research criteria have been developed). There are, however, numerous possible manifestations of EDNOS other than BED.
