Abstract：
Numerous lines of research indicate that our social brain involves a network of cortical and subcortical brain regions that are responsible for sensing and controlling body movements. However, it remains unclear whether movement disorders have a systematic impact on social cognition. To address this question, we conducted a systematic review examining the influence of hyperkinetic movement disorders (including Huntington disease, Tourette syndrome, dystonia, and essential tremor) on social cognition. Following the PRISMA guidelines and registering the protocol in the PROSPERO database (CRD42022327459), we analyzed 50 published studies focusing on theory of mind (ToM), social perception, and empathy. The results from these studies provide evidence of impairments in ToM and social perception in all hyperkinetic movement disorders, particularly during the recognition of negative emotions. Additionally, individuals with Huntington\'s Disease and Tourette syndrome exhibit empathy disorders. These findings support the functional role of subcortical structures (such as the basal ganglia and cerebellum), which are primarily responsible for movement disorders, in deficits related to social cognition.
摘要：
许多研究表明，我们的社交大脑涉及皮质和皮质下脑区域的网络，这些区域负责感知和控制身体运动。然而,目前尚不清楚运动障碍是否会对社会认知产生系统性影响.为了解决这个问题，我们进行了一项系统评价，检查多动性运动障碍（包括亨廷顿病，Tourette综合征,肌张力障碍,和特发性震颤）对社会认知的影响。遵循PRISMA指南并在PROSPERO数据库（CRD42022327459）中注册协议，我们分析了50项发表的研究，重点是心理理论(ToM)，社会感知，和同理心。这些研究的结果提供了所有多动性运动障碍的ToM和社会感知受损的证据，特别是在识别负面情绪的过程中。此外,患有亨廷顿病和抽动症的个体表现出共情障碍。这些发现支持皮质下结构（如基底神经节和小脑）的功能作用，主要负责运动障碍，与社会认知有关的缺陷。
