What's New for Eating Disorders in the DSM-5? by Mae Lynn Reyes-Rodriguez, Ph.D.

The new category in the DSM-5 is now called Feeding and Eating Disorders and includes presentations that occur both in children and adults, namely pica and rumination disorders, avoidant/restrictive food intake disorder (ARFID), anorexia nervosa, bulimia nervosa, binge eating disorder, and other specified feeding and eating disorders (OSFED) (1). The most relevant changes between the DSM-IV and DSM-5 for anorexia nervosa are the elimination of amenorrhea and the phrasing of the criterion related to fear of weight gain to include a  behavioral component. For bulimia nervosa, the reduction of the frequency of binges from twice to once per week over a 3-month period was the most significant change.
Finally, binge eating disorder was recognized as a distinct eating disorder (ED) marked by the same frequency of binge eating as described for bulimia nervosa.
