摘要
目的探讨影像学分型与急性脑梗死患者认知功能关系。方法对136例急性大脑梗死患者于发病后24-72h内行颅脑MRI检查确定梗死部位、测量病灶大小并作出影像学分型,于发病1周内,在患者床前采用简易精神状态检查法(mini-mental state examination,MMSE),检测患者的认知功能,并同步进行事件相关电位P300的检测,判断患者认知功能的情况,对比分析应用MRI 进行的影像学分型与认知功能关系。结果额叶、颞叶脑梗死患者的MMSE和WAIS-RC评分明显低于顶枕叶和基底节区梗死患者,P300潜伏时明显长于顶枕叶和基底节区梗死的患者,但其P300波幅低于顶枕叶和基底节区梗死的患者;中梗死和多发性梗死患者的MMSE和WAIS-RC评分明显低于顶枕叶和基底节区梗死患者,P300潜伏时明显长于顶枕叶和基底节区梗死的患者,但其P300波幅低于顶枕叶和基底节区梗死的患者。结论影像学分型与急性脑梗死患者认知功能有相关性。
Objective To study the correlation between brain photogrophic classification and cognitive function of acute cerebral infarction. Methods A hundred and thirty - six eases of acute cerebral infarction were prospectively examined by brain MRI within 48 - 72 hours after stroke, the location, extent of focal lesions and the brain photogrophic classification were observed in the same time. Within a week after stroke, cognitive function were assessed with mini - mental state examination（MMSE） ,WAIS - RC and event - related potential P300 were aim tested. To analyze the correlation between brain photogrophic classification and cognitive function. Results Scores of frontal , temporal , middle size and multiple infarction were lower than parieto - occipital , basal ganglia lesions all together, although Pw0 latent period of former infarctions were longer than the latter one , P30o amplitude were in reverse order . Conclusion There is a correlation between brain photogrophic classification and cognitive function of acute cerebral infarction acute ischemic stroke.
