程度不同脑白质疏松症患者认知功能特点研究

目的探讨程度不同脑白质疏松症(LA)患者认知功能的特点。方法采用MoCA量表分别测定66例程度不同LA患者及49例健康对照组的认知功能,对比程度不同LA与认知功能的关系,统计两者之间的相关性。结果LA患者的认知功能障碍随脑白质病变程度加重而加重,Ⅳ型LA患者的语言、记忆、视空间结构与执行功能均低于Ⅰ型LA患者和对照组(PP<0.05);各型LA患者的命名、注意力、抽象、定向力等未受影响(P>0.05)。结论LA患者的认知功能与损伤程度有关,轻度LA不影响认知功能,脑白质疏松的面积越大,认知功能下降越明显,主要引起语言、记忆、视空间和执行能力的下降。

Cognitive Function of the Patients with Leukoaraiosis at Different Extent

Objective To explore the characteristics of cognitive function in patients with leukoaraiosis(LA)at different extent.Methods The cognitive function of 66 patients with different extent of LA and 49 healthy controls were measured using the MoCA scale,and the relationship between the cognitive function and the extent of LA was evaluated.Results The LA was more severe,the cognitive function of patients was more poor.The cognitive function of patients with type Ⅳ LA significantly decreased than the patients with type Ⅰ LA and the controls,especially in the language,memory,visuoconstructional and executive functions(P<0.05).While the function of naming,attention,abstraction and orientation showed no significant difference between the patients with LA and the controls(P>0.05).Conclusion Moderate and severe LA may cause impairment of cognitive function.
