Neuroradiological and neuropsychological assessment in anorexia nervosa

Seventeen patients with anorexia nervosa were examined by computed tomography (CT) and psychometry and compared with ten normal control subjects. The patients were found to have enlarged external cerebrospinal fluid spaces compared to controls. No differences were found in ventricular size and X-ray absorption density measurements between patients and controls. The patients performed abnormally on the symbol digit test, the scores of which displayed a significant negative correlation with the CT scan changes.
