摘    要:目的 探讨缺血性卒中患者急性期认知障碍的特点。
方法 本研究为前瞻性研究,连续选取2011年3月~2012年6月广州市第一人民医院神经内科住院的
急性缺血性卒中患者220例为病例组,同时在社区、体检中心、患者家属中收集健康对照者146例为
对照组,采用蒙特利尔认知评估量表(Montreal Cognitive Assessment,MoCA)、简易精神状态检查量表
(Mini-Mental State Examination,MMSE)对研究对象进行测评,依据MMSE和MoCA总分将病例组分为4
个亚组,A组(MMSE<26分,MoCA≤23分)93例,B组(MMSE得分在26~27分,MoCA≤23分)36例,C组
(MMSE≥28分,MoCA≤23分)24例,D组(MMSE、MoCA得分均正常)67例,评估各亚分组认知功能下降
的情况。
结果 缺血性卒中急性期患者的MMSE总分(25.07±3.99),MoCA总分(17.70±5.77)均较正常对照
组的MMSE总分(27.73±1.89)和MoCA总分(23.96±3.44)下降(P<0.05)。病例组和对照组MoCA各
亚项比较,命名项目比较差异无显著性[病例组3(2,3),对照组3(2,3),P =0.159]。MoCA各亚项目
病例组的A组{视空间和执行功能[1(0,2)]、命名[2(1,3)],记忆[1(0,2)]、注意力[3(2,5)]、
语言[0(0,0)]、抽象[0(0,1)]、定向力[4(3,5)]}、B亚组{视空间和执行功能[1(1,2)]、命
名[2(1,3)],记忆[2(0,3)]、注意力[5(4,6)]、语言[0(0,0)]、抽象[1(1,2)]、定向力[6(5,
6)]}均较对照组{视空间和执行功能[4(3,5)]、命名[3(2,3)],记忆[3(2,4)]、注意力[6(5,
6)]、语言[2(1,2)]、抽象[2(1,2)]、定向力[6(6,6)]}下降(P<0.05),C组患者在视空间和
执行功能[2(1,3.75)]、语言[0(0,0)]、记忆[2(1,3)]3个分项得分与对照组{视空间和执行功
能[4(3,5)],语言[2(1,2)],记忆[3(2,4)]}比较差异均具有显著性(P<0.05)。
结论 急性期缺血性卒中患者存在认知受损的表现,其认知受损可累及多个认知域,而在MMSE不
能识别的轻度认知障碍患者中则以视空间和执行功能异常、语言障碍和记忆下降为主要临床表现。

Abstract:Objective To explore the features of cognitive impairment among patients with acute ischemic stroke. Methods In this prospective study, data were collected consecutively from 220 in-patients at the Neurology Department of Guangzhou First People's Hospital from March 2011 to June 2012. These patients were assessed with both Montreal Cognitive Assessment (MoCA) and Mini-Mental State Examination (MMSE) at the day of enrollment. Simultaneously, a control group of 146 healthy individuals from matched background was also set up. Control subjects were enrolled from community centers, physical examination center in our hospital and some of them were relatives of the patients as well. The patients were classiifed into subgroups based on the total scores of MoCA and MMSE, respectively. There are four subgroup: Group A (MMSE〈26, MoCA 23) with 93 patients, Group B (the scores of MMSE are between 26~27, MoCA 23) with 36 patients, Group C (MMSE 28, MOCA 23) with 24 patients, Group D (those with normal scores in both MMSE and MOCA) with 67 patients. Results Patients scored less than the controls overall on both the MMSE (25.07±3.99 vs 27.73±1.89) and MoCA (17.70±5.77 vs 23.96±3.44), (P〈0.05). There is no statistic difference in the naming subtests of MoCA in the two groups (patient group 32, 3], control group 32, 3], P=0.159). A comparison of the subtest scores of MoCA suggests that the subgroup A (visuospatial/executive function 1{0, 2}], naming 2{1, 3}], recall 1{0, 2}], attention 3{2, 5}], language 0{0, 0}], abstraction 0{0, 1}], orientation 4{3, 5}]) and subgroup B (visuospatial/executive function 1{1, 2}], naming 2{1, 3}], recall 2{0, 3}], attention 5{4, 6}], language 0{0, 0}], abstraction 1{1, 2}], orientation 6{5, 6}]) have worse performances than the control group (visuospatial/executive function 4{3, 5}], naming 3{2, 3}], recall 3{2, 4}], attention 6{5, 6}], language 2{1, 2}], abstraction 2{1, 2}], orientation 6{6, 6}]) (P〈0.05
