Neurology:小脑在帕金森病中意义非同寻常

小脑在帕金森中意义非同寻常

除运动症状外,帕金森病(PD)患者经常表现出认知和精神障碍。运动、联想和边缘丘脑-纹状体-皮层环路的失调有力地促进了这些症状的出现。

最近的一个假设是,这些环路也有一个小脑结点。一些研究已经产生了有利于小脑参与运动症状的大量论据,PD相关运动网络的活动增加与运动症状的严重程度相关。静止状态的研究报告显示,在没有多巴胺能药物治疗的情况下,小脑与顶叶和运动前皮层之间的功能连接增加。这些结果表明,PD的小脑参与超出了震颤的范围。

除了运动相关的小脑异常外,一些结果表明小脑与PD的认知和精神领域有关。然而,基于对不同症状的全面评估,目前还缺乏对小脑代谢和这三个领域之间联系的明确描述。

藉此,法国Rennes University Hospital的Florence Le Jeune等人,对90名PD患者进行了全面的运动、认知和精神评估,并将主成分分析(PCA)与18氟脱氧葡萄糖(FDG)-PET相结合,以测试两个假设:

1. 这些临床领域中的每一个都与特定小脑结构的代谢变化有关
2. 这些临床相关的小脑结构与上脑区域有特定的代谢相关模式。

他们发现,损伤的严重程度与前叶和蚓部(运动领域)、右侧Crus I、Crus II和declive(认知领域)以及右侧Crus I和Crus II(精神领域)的代谢增加有关。

此外,他们还发现运动和认知领域的分布和重叠的代谢相关模式,但不完全相同。特定的脑上结构(皮质结构、基底神经节和丘脑)与每个小脑集群都有强烈的相关性。

这个研究的重要意义在于,证实了小脑在帕金森病非运动领域的作用,不同的但重叠的代谢相关模式表明小脑-丘脑-纹状体-皮质环路的参与。
