摘要 目的探讨轻度血管性认知损害(mild vascular cognitive impairment,MVCI)与脑白质损害及血浆同型半胱氨酸(homocysteine,Hcy)间的关系及意义。方法对56例MVCI患者及60例认知功能正常的老年人完成神经心理学评估,头颅MRI检查和测定血浆同型半胱氨酸。结果 (1)MVCI组血浆Hcy浓度(31.28±2.19)μmol/L显著高于正常对照组(18.37±1.34)μmol/L(P<0.05);(2)MCVI组有显著脑白质损害(P<0.05);(3)Hcy浓度越高,脑白质损害越显著(P<0.05);(4)轻度血管性认知损害与年龄,高Hcy,中、重度WML有关。结论高Hcy血症可能通过引起脑内小动脉硬化而导致WML。MVCI与年龄,高Hcy,中、重度WML有关,这为早期预警及干预提供一定帮助。
