Tourette syndrome (TS) is a neurological disorder characterized by vocal and motor tics and is associated with cortical–striatal–thalamic–cortical circuit (CSTC) dysfunction and hyperexcitability of cortical limbic and motor regions, which are thought to lead to the occurrence of tics. Importantly, individuals with TS often report that their tics are preceded by ‘premonitory sensory phenomena’ (PSP) that are described as uncomfortable cognitive or bodily sensations that precede the execution of a tic, and are experienced as a strong urge for motor discharge. While the precise role played by PSP in the occurrence of tics is controversial, PSP are nonetheless of considerable theoretical and clinical importance in TS, not least because they form the core component in many of the behavioural therapies that are currently used in the treatment of tic disorders. In this study, we investigated the brain structure correlates of PSP. Specifically, we conducted a whole‐brain analysis of cortical (grey matter) thickness in 29 children and young adults with TS and investigated the association between grey matter thickness and PSP. We demonstrate for the first time that PSP are inversely associated with grey matter thickness measurements within the insula and sensorimotor cortex. We also demonstrate that grey matter thickness is significantly reduced in these areas in individuals with TS relative to a closely age‐ and gender‐matched group of typically developing individuals and that PSP ratings are significantly correlated with tic severity.

在患有图雷特综合征的年轻人中,先兆冲动与岛叶和感觉运动皮层内灰质厚度的减少有关。

Tourette 综合征 (TS) 是一种以发声和运动抽搐为特征的神经系统疾病,与皮质-纹状体-丘脑-皮质回路 (CSTC) 功能障碍以及皮质边缘和运动区域的过度兴奋有关,这被认为会导致抽搐的发生. 重要的是,患有 TS 的人经常报告说,他们的抽搐之前有“预感感觉现象”(PSP),这被描述为在抽搐执行之前不舒服的认知或身体感觉,并且被体验为强烈的运动放电冲动。虽然 PSP 在抽动发生中的确切作用存在争议,但 PSP 在 TS 中具有相当大的理论和临床重要性,尤其是因为它们构成了目前用于治疗抽动障碍的许多行为疗法的核心组成部分。在这项研究中,我们研究了 PSP 的大脑结构相关性。具体来说,我们对 29 名患有 TS 的儿童和年轻人的皮质(灰质)厚度进行了全脑分析,并调查了灰质厚度与 PSP 之间的关系。我们首次证明 PSP 与脑岛和感觉运动皮层内的灰质厚度测量呈负相关。我们还证明,相对于年龄和性别密切匹配的典型发育个体群体,TS 患者这些区域的灰质厚度显着降低,并且 PSP 评分与抽动严重程度显着相关。我们研究了 PSP 的大脑结构相关性。具体来说,我们对 29 名患有 TS 的儿童和年轻人的皮质(灰质)厚度进行了全脑分析,并调查了灰质厚度与 PSP 之间的关系。我们首次证明 PSP 与脑岛和感觉运动皮层内的灰质厚度测量呈负相关。我们还证明,相对于年龄和性别密切匹配的典型发育个体群体,TS 患者这些区域的灰质厚度显着降低,并且 PSP 评分与抽动严重程度显着相关。我们研究了 PSP 的大脑结构相关性。具体来说,我们对 29 名患有 TS 的儿童和年轻人的皮质(灰质)厚度进行了全脑分析,并调查了灰质厚度与 PSP 之间的关系。我们首次证明 PSP 与脑岛和感觉运动皮层内的灰质厚度测量呈负相关。我们还证明,相对于年龄和性别密切匹配的典型发育个体群体,TS 患者这些区域的灰质厚度显着降低,并且 PSP 评分与抽动严重程度显着相关。我们对 29 名患有 TS 的儿童和年轻人的皮质(灰质)厚度进行了全脑分析,并调查了灰质厚度与 PSP 之间的关系。我们首次证明 PSP 与脑岛和感觉运动皮层内的灰质厚度测量呈负相关。我们还证明,相对于年龄和性别密切匹配的典型发育个体群体,TS 患者这些区域的灰质厚度显着降低,并且 PSP 评分与抽动严重程度显着相关。我们对 29 名患有 TS 的儿童和年轻人的皮质(灰质)厚度进行了全脑分析,并调查了灰质厚度与 PSP 之间的关系。我们首次证明 PSP 与脑岛和感觉运动皮层内的灰质厚度测量呈负相关。我们还证明,相对于年龄和性别密切匹配的典型发育个体群体,TS 患者这些区域的灰质厚度显着降低,并且 PSP 评分与抽动严重程度显着相关。
