【摘要】 目的探讨事件相关电位P300对早期血管性痴呆的诊断价值。方法选择50例血管性痴呆患者(血管性痴呆组)、49例动脉硬化症无痴呆患者(动脉粥样硬化组)和48名健康人(健康人组)分别进行P300检查,比较三组的检查结果。结果血管性痴呆组P300潜伏期较动脉粥样硬化组、健康人组明显延长,波幅降低,差异有统计学意义(P<0.01)。结论事件相关电位P300检测在血管性痴呆早期诊断中具有较高的应用价值。更多还原

【Abstract】 Objective To explore the value of event related potential P300 in early diagnosis of vascular dementia. Methods Inspection of P300 was performed between 50 cases of patients with vascular dementia( group of dementia),49 arteriosclerosis patients without dementia( group of arteriosclerosis) and 48 healthy people( group of healthy people). Results The P300 incubation period of the group of dementia was prolonged significantly and amplitude decreased compared with the group of arteriosclerosis and the group of healthy people. The difference was statistically significant between the compared groups( P < 0. 01). Conclusion Event related potential checking has higher application value in early diagnosis of vascular dementia.更多还原
