摘要(Abstract):
目的探讨高同型半胱氨酸血症(Hhcy)对脑小血管病(SVD)患者认知功能的影响。方法 142例SVD患者根据认知功能分为痴呆组、认知功能障碍非痴呆组、认知功能正常组,测定研究对象血浆同型半胱氨酸(Hcy)水平及MMSE、画钟测验评分。结果 (1)Hcy水平痴呆组明显高于认知功能障碍非痴呆组(P<0.05),认知功能障碍非痴呆组高于认知功能正常组。(2)Logistic回归分析得出Hcy水平升高是小血管病患者认知功能损害的独立危险因素。(3)Hhcy对MMSE总评分、定向功能、语言功能以及反应视空间功能、动作的计划性和执行功能画钟测验均有独立的危险性,其OR值分别为1.044、1.057、1.040、1.251。结论 Hcy水平升高是脑小血管病认知功能损伤的独立危险因素,对总体认知功能、定向功能、语言功能以及视空间功能、动作的计划性和执行功能有独立影响作用。
