Neuropsychological test performance of bulimic patients.

Thirty subjects with DSM-III diagnoses of bulimia were compared to 30 matched controls on the Luria-Nebraska Neuropsychological Battery. The bulimics showed poorer performance on tasks associated with functioning of the right frontal cortical area, primarily tasks involving speed of drawing geometric figures. The similarities of the findings to previous findings with anorexic samples and patients with affective disorders are discussed.
