This study examined the effects of weight loss and nutritional status on the cognitive performance of patients with anorexia nervosa. The intellectual, memory, attentional, verbal fluency and visuospatial abilities of 34 females with anorexia were compared to that of 31 normal weight-for-height females. Group differences in anxiety and depression were found but neither variable was related to the cognitive performance of patients with anorexia. Moreover, nutritional status and weight loss bore little relationship to the cognitive scores of the patient group. Overall, patients with anorexia were found to be deficient in their ability to recall meaningful prose and visuospatial information. The failure to find many cognitive deficits in this sample may reflect the fact that few patients with anorexia exhibited frank nutritional deficiencies.
本研究考察了体重减轻和营养状况对神经性厌食症患者认知表现的影响。将34名神经性厌食症女性患者的智力、记忆、注意力、语言流畅性和视觉空间能力与31名身高体重正常的女性进行了比较。发现两组在焦虑和抑郁方面存在差异，但这两个变量均与神经性厌食症患者的认知表现无关。此外，营养状况和体重减轻与患者组的认知得分几乎没有关系。总体而言，发现神经性厌食症患者在回忆有意义的散文和视觉空间信息方面能力不足。在这个样本中未能发现许多认知缺陷，可能反映了这样一个事实，即很少有神经性厌食症患者表现出明显的营养缺乏。
