We examined brain activation in the presence of eating disorders while processing unpleasant words concerning body images using functional magnetic resonance imaging（fMRI）. Anorexia nervosa restricting type （AN-R）and anorexia nervosa binge-eating/purging type（AN-BP）patients showed significant amygdala activation. Farther, AN-BP and bulimia nervosa（BN）patients showed significant medial prefrontal cortex activation. Next, we conducted short-term integrated group therapy for eating disorders. After treatment, depressive scores of POMS and emotional-oriented coping scores of CISS were significantly decreased, and EAT scores and self-esteem scores of RSES were significantly increased.
