【摘要】 目的分析脑梗死患者的事件相关电位与认知障碍的关系。方法应用简易精神状态检查量表 (MMSE)和相关事件电位 (ERP)的检测 ,分析脑梗死患者的认知功能变化。结果脑梗死组 (32例 )与对照组 (32例 )之间P30 0潜伏期 (P30 0PL)的比较有非常显著性差异 (P <0 .0 1)。从波形看 ,脑梗死组波幅较低 ,P30 0波变异大 ,波形不规则。两组MMSE评分亦有非常显著性差异(P <0 .0 1)。脑梗死组P30 0潜伏期与MMSE评分呈负相关 (r =-0 .2 8,P <0 .0 1)。结论P30 0潜伏期可客观地反映急性期脑梗死患者的认知功能障碍更多还原

【Abstract】 Objective To study the cognitive disorder in acute brain infarction. MethodCognition was meaured by P300 Peak Latency and The MMSE Scale for 32 patients with acute brain infarction. Results There are significant difference in P300 Peak Latency and The MMSE Scale scores between the patients and controls. ConclusionP300 Peak Latency could indicate the cognitive disorder in patients with acute brain infarction.更多还原
