针刺对脑白质疏松轻度认知障碍功能磁共振的影响

目的观察针刺前后脑白质疏松轻度认知障碍的脑功能磁共振变化,探索针刺干预轻度认知障碍的作用机理和疗效的客观化标准。方法以脑白质疏松轻度认知障碍为研究对象,以功能磁共振为研究手段,参考临床实际情况,长时程针刺干预,通过神经心理学量表评价脑白质疏松轻度认知障碍的临床变化。结果针刺前听觉任务激活的脑区包括颞叶的颞上回(BA22)、颞中回(BA21)、颞极区(BA38),额叶的体感皮层(BA1)和前运动皮层(BA6)。针刺后激活的脑区包括颞叶的颞上回(BA22),额叶的额眶叶(BA11)、额极区(BA10)、额叶被盖。被激活脑区明显少于针刺前被激活区。结论LACI相关的脑功能区涉及到额、颞叶,表现为执行听觉任务时颞叶皮质激活增多,前额叶皮质未激活;长时程针刺后颞叶皮质激活减少,前额叶皮质激活。fMRI可以为轻度认知障碍的诊断、疗效判断以及针刺作用机理研究提供可视化依据。长时程针刺可以作为LACI的有效干预手段之一,能够减少被激活脑区,提高任务刺激加工效率。

Impact of Acupuncture on Functional Magnetic Resonance Imaging in Leukoaraiosis with Mild Cognitive Impairment

Objective To observe brain functional magnetic resonance imaging(fMRI)changes in leukoaraiosis with mild cognitive impairment before and after acupuncture and explore the mechanism and the objective criteria of the efficacy of acupuncture intervention on mild cognitive impairment. Methods Leukoaraiosis with mild cognitive impairment(LACI)cases were taken as the subjects in the research. fMRI was applied as the means. In reference with clinical practical conditions,long-term acupuncture intervention and neur...
