【摘要】：目的探讨脑电图对老年轻度认知功能障碍转变为痴呆症的预警价值。方法 30例老年轻度认知功能障碍患者为对照组,另选取52例阿尔茨海默病(AD)患者为研究组。患者均接受脑电图检查,比较两组脑电图特点、脑电信号复杂度。结果两组背景节律主要为α节律,对照组表现为前移或泛化,而研究组表现为变慢,波幅降低;两组除T6导联其余各导联、全脑、左右额颞区及左右半球的复杂度相比差异有统计学意义(P0.05);研究组前颞区(F7、F8)及前额区(FP1、FP2)导联处的复杂度低于其他导联(P0.05);研究组右颞区脑电信号复杂度高于右额区(P0.05)。结论脑电图对老年轻度认知功能障碍转变为痴呆症具有一定预警价值。
[Abstract]:Objective to explore the early warning value of electroencephalogram (EEG) in the elderly patients with mild cognitive impairment (MCI) to dementia. Methods 30 elderly patients with mild cognitive impairment were used as control group. In addition, 52 patients with Alzheimer's disease (AD) were selected as the study group. The patients were examined by electroencephalogram (EEG) to compare the EEG characteristics and EEG complexity between the two groups. Results the background rhythm of the two groups was mainly alpha rhythm, while the control group showed forward movement or generalization. In the study group, the results showed that the amplitude of the wave was decreased, and the brain of the two groups, except the T6 lead, was decreased. The complexity of the left and right frontotemporal regions and the left and right hemispheres was significantly higher than that of the left and right frontal-temporal regions, and the complexity of the F7F8) and FP1 / FP2) leads in the study group was lower than that of the other leads (P0.05), and the complexity of the right temporal EEG in the study group was higher than that in the right frontal area. Conclusion electroencephalogram (EEG) is an early warning method for mild cognitive impairment to dementia in the elderly.
