散发性帕金森病(sPD)的许多临床症状不能完全用纹状体和黑质之间的典型锥体外系的病变来解释。因此,本研究旨在通过磁共振成像(MRI)探索与sPD的多种复杂临床症状相关的其他脑区新的潜在损伤发病机制。本研究共招募了65名中期sPD患者和35名健康对照。使用MRI的基于顶点的形态通过基于种子的分析来评估皮质结构连通性。选择使用脑大小作为sPD和对照之间的协变量的回归分析得出的皮质厚度变薄的脑区域中的七个不同簇作为种子。结果表明,皮质结构连通性的显著改变主要发生在双侧额叶眶,可操作的,三角形,前中心,直肌,辅助电机,颞极,角度,Heschl,顶叶,超边际,postcentral,precuneus,枕骨,语言,Cuneus,罗兰迪-手术,扣带,海马旁,calcarine,嗅觉,脑岛,旁中央小叶,和sPD中期的梭形区域。这些发现表明,皮质结构连通性的广泛改变是导致sPD多种复杂临床症状的可能发病机制之一。
Many clinical symptoms of sporadic Parkinson\'s disease (sPD) cannot be completely explained by a lesion of the simple typical extrapyramidal circuit between the striatum and substantia nigra. Therefore, this study aimed to explore the new potential damaged pathogenesis of other brain regions associated with the multiple and complex clinical symptoms of sPD through magnetic resonance imaging (MRI). A total of 65 patients with mid-stage sPD and 35 healthy controls were recruited in this study. Cortical structural connectivity was assessed by seed-based analysis using the vertex-based morphology of MRI. Seven different clusters in the brain regions of cortical thickness thinning derived from the regression analysis using brain size as covariates between sPD and control were selected as seeds. Results showed that the significant alteration of cortical structural connectivity mainly occurred in the bilateral frontal orbital, opercular, triangular, precentral, rectus, supplementary-motor, temporal pole, angular, Heschl, parietal, supramarginal, postcentral, precuneus, occipital, lingual, cuneus, Rolandic-opercular, cingulum, parahippocampal, calcarine, olfactory, insula, paracentral-lobule, and fusiform regions at the mid-stage of sPD. These findings suggested that the extensive alteration of cortical structural connectivity is one of possible pathogenesis resulting in the multiple and complex clinical symptoms in sPD.
