title: [Anorexia nervosa and cerebral atrophy in adolescents].
abstract: OBJECTIVE
  The incidence of cerebral atrophy in patients with anorexia nervosa and its relation to nutritional parameters has not been considered yet.
  
  
  METHODS
  The medical records of 55 patients were reviewed. 47 of them underwent a cerebral magnetic resonance, anthropometric and nutritional study.
  
  
  RESULTS
  Cerebral atrophy was found in 10 (21.2%) out of the 47 patients studied. Those patients with cerebral atrophy showed an older age and greater percentage of weight loss than patients without atrophy (p = 0.014 and p = 0.001) but lower triceps skinfold average (p = 0.001).
  
  
  CONCLUSIONS
  Cerebral atrophy is common in patients with anorexia nervosa, mainly in those with a severe weight loss and lower body fat.
