OBJECTIVE
Neuroimaging evidences in eating disorder (ED) patients document dysfunctional neural activity of the posterior parietal cortex, which is engaged in the representation of body schema. Yet a full neuropsychological investigation of body schema representation in ED patients is lacking. We examined mental imagery and body schema representation in patients with bulimia nervosa (BN) and binge eating disorder (BED).
METHOD
Consecutive samples of 15 BN patients and 15 BED patients were compared with two groups of 15 age-matched controls in tasks requiring body or object mental transformation.
RESULTS
BN, but not BED patients, were selectively impaired in the mental transformation of their own body, although this deficit was not correlated with measures of body dissatisfaction. In contrast, no patient group was impaired in the mental transformation of external objects.
DISCUSSION
Results showed altered self-body representation in BN, but not BED patients, as the neuropsychological consequences of posterior parietal cortex dysfunctions.
目的
饮食障碍（ED）患者的神经影像学证据记录了后顶叶皮层的神经活动功能障碍，该区域参与了身体图式的表示。然而，ED 患者的身体图式表示的全面神经心理学研究还很缺乏。我们研究了神经性贪食症（BN）和暴食障碍（BED）患者的心理意象和身体图式表示。
方法
连续纳入 15 名 BN 患者和 15 名 BED 患者，并与两组年龄匹配的 15 名对照在需要身体或物体心理转换的任务中进行比较。
结果
BN 患者，而不是 BED 患者，在自身身体的心理转换中受到选择性损伤，尽管这种缺陷与身体不满的测量无关。相比之下，没有患者组在外部物体的心理转换中受到损伤。
讨论
结果表明 BN 患者的自我身体表示发生改变，而不是 BED 患者，这是后顶叶皮层功能障碍的神经心理学后果。
