Abstract

目的 探讨轻度认知障碍(MCI)患者情感记忆编码和提取受损的特点,为极早发现MCI和干预治疗前移评估提供理论依据.方法人选MCI组34例,选取30例健康老年人作为对照组,所有受试者均进行情感记忆编码和提取测试.结果MCI组情感图片记住数(REM)(21.32±7.29)%明显低于对照组(26.00±9.57)%(P＜0.05),MCI组情感图片靶片提取率(85.44±4.94)%与对照组(96.76±2.18)%比较有极显著差异(P＜0.01).MCI组IPreti与(PP+UP)reti比较无显著性差异(t=1.41,P＞0.05),对照组IPreti与(PP+UP)reti比较有显著性差异(t=15.24,P＜0.05).两组间IPreti比较无显著性(t=1.28,P＞0.05),(PP+UP)reti比较有极显著性差异((t=25.49,P＜0.01).PPreti (Pleasant pictures retrieval index)、Upreti(unpleasant pictures retrieval index)IPreti(indifferent picturesretrieval index).结论MCI患者存在情感记忆编码受损,载有情感内容的图片不能增强MCI患者情感记忆提取,情感记忆编码和提取测试为极早发现MCI有效工具之一。
