摘要:

［目的］ 观察脑卒中后脑电图变化与认知损害的关系。［方法］ 采用148例脑卒中患者为观察组。采用韦氏记忆量表、韦氏成人智力量表、威斯康星卡片分类试验、连线测验A和测验B等检测认知功能的改变。［结果］ ① 脑卒中后认知指标如触觉记忆、执行正确、执行错误,注意机能中的背数、视觉再认、视觉再生,连线A、连线B等观察组和对照组比较差异有显著性意义（P<0.05）。② 脑卒中后脑电图异常率87.9 %，其中轻度异常83例（56.08%），中度异常36例（24.32%），重度异常11例（7.43%）。［结论］ 脑卒中后认知有明显的损害。脑卒中后脑电地图有相应的改变，并对定位及认知损害的判断有一定的参考价值。

Abstract:

［Objective］ To observe the relationship between cognitive impairment and changes in electroencephalography after stroke. ［Methods］ One hundred and forty eight patients with stroke were chosen as observation group. The cognitive function was tested by Wechsler Memory Scale (WMS), Wechsler Adult Intelligence Scale (WAIS), Wisconsin Card Sorting Test (WSCT), Trail Making Test A and Trail Making Test B and etc. ［Results］ ① There were significant differences in cognitive indicators (such as tactile memory, perform correct, perform incorrect), attention function (such as recitation figure, vision recognition, vision regeneration), Trail Making Test A and Trail Making Test B between observation and control groups (P<0.05). ② The abnormal rate of electroencephalography after stroke was 87.9%. Among all of the 148 cases, 83 cases were mildly abnormal (56.08%), 36 cases were moderately abnormal (24.32%) and 11 cases were severely abnormal (7.43%). ［Conclusions］ There is obvious damage to cognitive function after stroke. The electroencephalography of patients is changed after stroke. And the changes are reference valuable to locate stoke and judge the cognitive impairment.
