在神经退行性疾病中，更好的记忆/认知意识（以更高的“元记忆监测准确性”为索引）与更强的认知修复结果有关。痴呆症前期的元记忆监测准确性的差异可能会影响治疗效果，但尚未得到系统的研究。我们采用回顾性置信度判断（RCJ）任务对社区居住的老年人进行常识识别：106例认知健康（HC）， 68例神经心理功能完好的主观认知衰退（SCD）， 14例遗忘性轻度认知障碍（aMCI）， 31例非遗忘性轻度认知障碍（naMCI）。参与者在对一般知识问题做出识别性回答后给出了信心评级。分析了识别精度、置信度、绝对和相对RCJ精度（即元记忆监测精度）。与HC和SCD相比，两个MCI组的绝对RCJ准确性明显较差，而naMCI组的相对RCJ准确性明显较差，但aMCI组没有。这一新颖的结果可能是由于naMCI中正确识别反应的可信度较低，并表明naMCI中较差的RCJ准确性可能归因于较差的性能监测。我们讨论了具有不同记忆/认知意识水平的不同临床前痴呆个体可能从针对其记忆/认知意识水平量身定制的认知修复策略中获益的可能性。
In neurodegenerative conditions, better memory/cognitive awareness, indexed by greater “metamemory monitoring accuracy”, is linked to stronger cognitive remediation outcomes. Differences in metamemory monitoring accuracy in predementia conditions, which could inform treatment effectiveness, have not been systematically investigated. We utilized a retrospective confidence judgment (RCJ) task for general knowledge recognition in community-dwelling older adults: 106 cognitively healthy (HC), 68 subjective cognitive decline (SCD) despite intact neuropsychological function, 14 amnestic mild cognitive impairment (aMCI), and 31 non-amnestic mild cognitive impairment (naMCI). Participants gave confidence ratings after making recognition responses to general knowledge questions. Recognition accuracy, confidence levels, and absolute and relative RCJ accuracy (i.e., metamemory monitoring accuracy) were analyzed. Compared to HC and SCD, absolute RCJ accuracy was significantly poorer in both MCI groups but relative RCJ accuracy was significantly poorer in naMCI, but not aMCI. This novel result may be driven by lower confidence for correct recognition responses in naMCI and suggests that poorer RCJ accuracy in naMCI may be attributable to poorer performance monitoring. We discuss results in relation to the possibility that individuals in distinct preclinical dementia conditions, who have different levels of memory/cognitive awareness, may differentially benefit from cognitive remediation strategies tailored to their levels of memory/cognitive awareness.
