Social cognition (SC) comprises an array of cognitive and affective abilities such as social perception, theory of mind, empathy, and social behavior. Previous studies have suggested the existence of deficits in several SC abilities in Parkinson disease (PD), although not unanimously.Objective:The aim of this study is to assess the SC construct and to explore its relationship with cognitive state in PD patients.Method:We compare 19 PD patients with cognitive decline, 27 cognitively preserved PD patients, and 29 healthy control (HC) individuals in social perception (static and dynamic emotional facial recognition), theory of mind, empathy, and social behavior tasks. We also assess processing speed, executive functions, memory, language, and visuospatial ability.Results:PD patients with cognitive decline perform worse than the other groups in both facial expression recognition tasks and theory of mind. Cognitively preserved PD patients only score worse than HCs in the static facial expression recognition task. We find several significant correlations between each of the SC deficits and diverse cognitive processes.Conclusions:The results indicate that some components of SC are impaired in PD patients. These problems seem to be related to a global cognitive decline rather than to specific deficits. Considering the importance of these abilities for social interaction, we suggest that SC be included in the assessment protocols in PD.

帕金森病患者的社会认知和认知衰退

社会认知 (SC) 包括一系列认知和情感能力,例如社会感知、心智理论、同理心和社会行为。以往的研究表明帕金森病(PD)患者存在多种 SC 能力缺陷,尽管并非一致。目的:本研究的目的是评估 SC 结构并探讨其与 PD 患者认知状态的关系。方法:我们比较了 19 名认知下降的 PD 患者、27 名认知保留的 PD 患者和 29 名健康对照 (HC) 个体在社会感知(静态和动态情绪面部识别)、心智理论、同理心和社会行为任务方面的情况。我们还评估处理速度、执行功能、记忆力、语言和视觉空间能力。结果:认知能力下降的 PD 患者在面部表情识别任务和心理理论方面的表现都比其他组差。认知保留的 PD 患者在静态面部表情识别任务中的得分仅低于 HC。我们发现每个 SC 缺陷与不同的认知过程之间存在几个显着的相关性。结论:结果表明,在 PD 患者中,SC 的某些成分受损。这些问题似乎与全球认知能力下降有关,而不是与特定缺陷有关。考虑到这些能力对社交互动的重要性,我们建议将 SC 纳入 PD 的评估协议中。我们发现每个 SC 缺陷与不同的认知过程之间存在几个显着的相关性。结论:结果表明,在 PD 患者中,SC 的某些成分受损。这些问题似乎与全球认知能力下降有关,而不是与特定缺陷有关。考虑到这些能力对社交互动的重要性,我们建议将 SC 纳入 PD 的评估协议中。我们发现每个 SC 缺陷与不同的认知过程之间存在几个显着的相关性。结论:结果表明,在 PD 患者中 SC 的某些成分受损。这些问题似乎与全球认知能力下降有关,而不是与特定缺陷有关。考虑到这些能力对社交互动的重要性,我们建议将 SC 纳入 PD 的评估协议中。
