Multiple sclerosis (MS) is associated with deficits in social cognition, the process underlying social interaction and cognitive function. However, the relationships between executive impairment and social cognition remain unclear in MS. Previous studies exclusively focused on group comparisons between healthy controls and patients with MS, treating the latter as a homogeneous population. The variability of socio- and neurocognitive profiles in this pathology therefore remains underexplored. In the present study, we used a cluster analytic approach to explore the heterogeneity of executive and social cognition skills in MS. A total of 106 patients with MS were compared with 53 healthy matched controls on executive (e.g., working memory) and social cognition (facial emotion recognition and theory of mind) performances. A cluster analysis was then performed, focusing on the MS sample, to explore the presence of differential patterns of interaction between executive and social cognition difficulties and their links to sociodemographic, clinical and cognitive variables. We identified three distinct functional profiles: patients with no executive or social cognition deficits (Cluster 1); patients with difficulties in facial emotion recognition and theory of mind and, to a lesser extent, executive functioning (Cluster 2); and patients with executive functioning difficulties only (Cluster 3). Clinical characteristics (disease duration, disability, fatigue) did not differ between clusters.

多发性硬化症的社会认知和执行功能:聚类分析方法

多发性硬化症 (MS) 与社会认知缺陷有关,这是社会互动和认知功能的潜在过程。然而,在 MS 中,执行障碍与社会认知之间的关系仍不清楚。以前的研究只关注健康对照组和 MS 患者之间的组比较,将后者视为同质人群。因此,这种病理学中社会认知和神经认知特征的变异性仍未得到充分探索。在本研究中,我们使用聚类分析方法来探索 MS 中执行和社会认知技能的异质性。共有 106 名 MS 患者与 53 名健康匹配的对照者在执行(例如,工作记忆)和社会认知(面部情绪识别和心理理论)表现方面进行了比较。然后进行聚类分析,重点关注 MS 样本,以探索执行和社会认知困难之间存在的不同交互模式及其与社会人口学、临床和认知变量的联系。我们确定了三种不同的功能特征:没有执行或社会认知缺陷的患者(集群 1);面部情绪识别和心智理论有困难的患者,在较小程度上,执行功能有困难(第 2 组);和仅执行功能困难的患者(第 3 组)。临床特征(疾病持续时间、残疾、疲劳)在集群之间没有差异。探索执行和社会认知困难之间相互作用的不同模式及其与社会人口学、临床和认知变量的联系。我们确定了三种不同的功能特征:没有执行或社会认知缺陷的患者(集群 1);面部情绪识别和心智理论有困难的患者,在较小程度上,执行功能有困难(第 2 组);和仅执行功能困难的患者(第 3 组)。临床特征(疾病持续时间、残疾、疲劳)在集群之间没有差异。探索执行和社会认知困难之间相互作用的不同模式及其与社会人口学、临床和认知变量的联系。我们确定了三种不同的功能特征:没有执行或社会认知缺陷的患者(集群 1);面部情绪识别和心智理论有困难的患者,在较小程度上,执行功能有困难(第 2 组);和仅执行功能困难的患者(第 3 组)。临床特征(疾病持续时间、残疾、疲劳)在集群之间没有差异。在较小程度上,执行功能(第 2 组);和仅执行功能困难的患者(第 3 组)。临床特征(疾病持续时间、残疾、疲劳)在集群之间没有差异。在较小程度上,执行功能(第 2 组);和仅执行功能困难的患者(第 3 组)。临床特征(疾病持续时间、残疾、疲劳)在集群之间没有差异。
