1、中华神经科杂志2014年5月第47卷第5期ChinJNeurol,May2014,Vo1.47.No.5·311·.非阿尔茨海默病认知损害.额叶与枕叶卒中患者的内隐记忆损害特征龚亮李秀汪凯王继华杨旭东冯磊【摘要】目的探讨额叶及枕叶卒中患者记忆损害的特征,了解卒中患者概念型内隐记忆(conceptionimplicitmemory,CIM)和知觉型内隐记忆(perceptionimplicitmemory,PIM)启动效应损害的特征。方法收集23例额叶卒中患者、21例枕叶卒中患者和与其匹配的26名健康对照者的内隐记忆启动效应结果,
2、同时进行外显记忆(即刻回忆、延时回忆、延时再认)和其他神经心理学背景测试。结果额叶卒中组与健康对照组相比CIM评分成绩较差,差异具有统计学意义[(1.964-1.00)分与(3.52±0.52)分,t=6.987,P<0.01],而其PIM评分与健康对照组差异无统计学意义;在即刻回忆、延时回忆、延时再认[(3.91±1.53)、(6.04±3.05)、(22.61±4.71)分]方面均较健康对照组[(5.42±1.06)、(8.19±1.60)、(25.38±3.24)分,t=2.428、3.990、3.138,均P<0.05]
3、差。枕叶卒中组PIM评分[(5.56±8.19)分]较健康对照组[(22.12±4.68)分]差异有统计学意义(t=0.011,P<0.01),CIM评分较健康对照组差异无统计学意义。结论额叶卒中患者存在CIM的损害而PIM相对保留,枕叶卒中患者存在明显的PIM的损害而CIM相对保留,证实了内隐记忆神经机制的双分离。【关键词】卒中;记忆障碍;神经心理学测验ImpairmentofimplicitmemoryinpatientswithfrontallobeandoccipitallobestrokeLiang,LiXiu,Wan
