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。

Objective To explore the value of event related potential P 300 in early diagnosis of vascular de-mentia.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 am -plitude decreased compared with the group of arteriosclerosis and the group of healthy people .The difference was sta-tistically significant between the compared groups ( P<0.01 ) .Conclusion Event related potential checking has higher application value in early diagnosis of vascular dementia .
