一些研究已经调查了神经性厌食症(AN)和暴食症(BN)患者的认知特征；相反，很少有研究评估暴食障碍(Bed)患者的认知特征。本研究的目的是比较卧床和卧床患者的决策、中心连贯性和定势转移。采用艾奥瓦州赌博测验(IGT)、Rey-Osterrieth复杂图形测验(RCFT)、威斯康星卡片分类测验(WCST)、试探测验(TMT)和海林句子完成测验(HSCT)对135名女性(45名女性，45名床位，45名健康对照)进行了测试。此外，采用贝克抑郁量表(BDI)评估抑郁症状。在统计分析中，受教育年限、年龄、身体质量指数(BMI)和抑郁严重程度被视为协变量。Bed和AN患者在所研究的领域中表现出比HC更高的认知损害发生率；此外，与AN患者相比，Bed患者的认知特征表现为决策能力和认知灵活性较差。认知表现与抑郁症状密切相关。在目前的样本中，出现了两种不同的神经认知特征：强烈的认知僵化和基于细节的中心一致性在AN患者中占主导地位，而缺乏注意力和难以适应新情况下的变化似乎更好地描述了卧床患者。了解EDS患者的不同认知特征可能对他们的心理治疗干预计划有重要意义。
Several studies have investigated the cognitive profile in patients with Anorexia Nervosa (AN) and Bulimia Nervosa (BN); on the contrary few studies have evaluated it in patients with Binge Eating Disorder (BED). The purpose of this study was to compare decision making, central coherence and set-shifting between BED and AN patients. A battery of neuropsychological tests including the Iowa Gambling Task (IGT), the Rey-Osterrieth Complex Figure Test (RCFT), the Wisconsin Card Sorting Test (WCST), the Trial Making Task (TMT) and the Hayling Sentence Completion Task (HSCT) were administered in a sample of 135 women (45 AN, 45 BED, 45 Healthy Controls [HC]). Furthermore, Beck Depression Inventory (BDI) was administered to evaluate depressive symptoms. Years of education, age, Body Mass Index (BMI) and depression severity were considered as covariates in statistical analyses. BED and AN patients showed high rates of cognitive impairment compared to HC on the domains investigated; furthermore, the cognitive profile of BED patients was characterised by poorer decision making and cognitive flexibility compared to patients with AN. Cognitive performance was strongly associated with depressive symptoms. In the present sample, two different neurocognitive profiles emerged: a strong cognitive rigidity and a central coherence based on the details was predominant in patients with AN, while a lack of attention and difficulty in adapting to changes in a new situation seemed to better describe patients with BED. The knowledge of the different cognitive profiles of EDs patients may be important for the planning their psychotherapeutic intervention.
