Persons with amnestic Mild Cognitive Impairment (aMCI) are at risk for experiencing changes in their daily functioning due to their memory impairment. The Memory Support System (MSS), a compensatory calendaring system, was developed to support functional independence in persons with aMCI (pwaMCI). This cross-sectional study examined procedural learning, declarative learning, and working memory as predictors of MSS learning efficiency in pwaMCI. Sixty pwaMCI participated in MSS training. The Serial Reaction Time Test and Mirror Tracing Test were used to assess procedural learning. The Rey Auditory Verbal Learning Test and CogState One Card Learning were used to assess declarative learning and the CogState One Back task was used to assess working memory. Multiple regression analyses were conducted to assess if procedural learning, declarative learning, and working memory predicted MSS learning efficiency. This study showed that declarative learning predicted MSS learning efficiency in pwaMCI, with less consistent results for procedural learning and non-significant results for working memory. Findings suggest that success in teaching compensatory tools is greater when training is offered in early aMCI before declarative learning skill is fully lost. Future studies should assess additional strategies to facilitate MSS learning in advanced aMCI.
患有遗忘型轻度认知障碍(aMCI)的人由于记忆障碍,其日常功能有发生变化的风险。记忆支持系统(MSS)是一种补偿性日程安排系统,旨在支持aMCI患者(pwaMCI)的功能独立性。这项横断面研究将程序学习、陈述性学习和工作记忆作为pwaMCI中MSS学习效率的预测指标进行了检验。60名pwaMCI患者参与了MSS训练。采用序列反应时测试和镜像追踪测试来评估程序学习。采用雷伊听觉词语学习测试和CogState单卡学习来评估陈述性学习,采用CogState 1-back任务来评估工作记忆。进行多元回归分析以评估程序学习、陈述性学习和工作记忆是否能预测MSS学习效率。本研究表明,陈述性学习可预测pwaMCI中的MSS学习效率,程序学习的结果不太一致,工作记忆的结果不显著。研究结果表明,在陈述性学习技能完全丧失之前的早期aMCI阶段提供训练时,补偿工具教学的成功率更高。未来的研究应评估在晚期aMCI中促进MSS学习的其他策略。
