In anorexia nervosa, part of the global gray matter loss persists over the long run. Region-specific gray matter loss in the anterior cingulate cortex is directly related to the severity of anorexia nervosa, indicating an important role of this area in the pathophysiology of the disorder. Further research is warranted to determine the cause, specificity, and functional consequences of this structural brain change in anorexia nervosa.

Although the programs from different countries and health care environments varied in terms of their purpose and operated within very different health care systems, many similarities were found to exist, including the use of a multidisciplinary staff and reliance on group treatment as the primary means of therapy. Marked differences were noted in terms of inclusion criteria and intensity of care.

The aim of this observational study was to examine the short-term effectiveness of a structured, largely manualised day hospital treatment, as well as the stability of short-term effects in patients with anorexia nervosa (AN) and bulimia nervosa (BN). Eighty-three patients, 47 with AN and 36 with BN, were assessed at pre-treatment, at the end of the day hospital treatment and at follow-up approximately one year after post-treatment. Outcome measures were body mass index (BMI), disturbed eating attitudes and behaviours assessed by the Eating Disorder Inventory (EDI), frequency of bingeing and purging, and general psychopathology assessed by the Symptom Checklist-90 (SCL-90). At the end of the day hospital treatment, significant improvements could be found on all outcome variables (frequency of binge eating/vomiting/laxative abuse, BMI and core EDI-subscales 'drive for thinness'/'bulimia'/'body dissatisfaction'). Effect sizes were generally large (.74 > d < 2.44). The effects were maintained or improved until follow-up (18 months). At follow-up, 40.2% of AN patients and 40.4% of BN patients could be classified as remitted. General psychopathological impairment was also significantly reduced at post-treatment and maintained until follow-up. The results demonstrate both the short-term effectiveness and long-term stability of day hospital treatment in a large sample of patients with anorexia and BN.
