| 摘 要： | 目的探讨遗忘型轻度认知障碍患者(aMCI)内隐记忆概念性启动和知觉性启动损害的特征。方法采用分类产生和图片辨别对35例aMCI患者和35名正常老年人的内隐记忆(概念性启动和知觉性启动)进行测试,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,并进行组间比较和分析。结果与正常老年组相比,aMCI患者组即刻回忆、延时回忆、延时再认、概念性启动成绩均差于正常对照组(P0.01)。两组在知觉性启动成绩差异无统计学意义(P0.05)。患者组概念性启动成绩与词汇流畅性成绩呈正相关(r=0.74,P0.01)。结论aMCI患者外显记忆及内隐记忆的概念性启动存在损害,且其概念性启动损害可能与其额叶功能减退存在一定的相关性。
