BACKGROUND Subjective memory complaints are a key component in mild cognitive impairment (MCI) diagnosis. However, studies that examined memory awareness among MCI participants have published contradictory results. One possible explanation for the inconsistent findings could be the disregard from the multidimensional structure of subjective memory. OBJECTIVES The present study is directed at assessing subjective memory among healthy and MCI participants, referring to three main types of memory: episodic, semantic, and working memory. METHOD Participants were 123 adults (aged 50-90). They were divided into two groups, the MCI group, and the control group, according to their objective cognitive performance in RAVL or Mo- CA tests. All participants filled a subjective memory questionnaire, assessing their awareness of episodic, semantic, and working memory. RESULTS MCI participants estimated their semantic memory as significantly lower in comparison to the estimation of the healthy controls. By contrast, MCI participants showed an overestimation of their episodic memory capabilities compared to the control group. No significant difference was found between groups (MCI and healthy controls) in evaluating their working memory. In addi- tion, for both groups, Pearson's correlation revealed a significant negative correlation between age and semantic memory evaluation. Such correlation was not found for subjective episodic memory. DISCUSSION Findings suggest that while people with MCI exhibit poor awareness of their episodic and working memory capabilities, their awareness of their decrease in semantic memory is appar- ently intact. Therefore, it is suggested that when using the self-report criterion for MCI diagnosis, clinicians should consider the patient's' semantic memory complaints.

主观记忆投诉作为MCI诊断的自我报告标准的新思考。

背景技术主观记忆抱怨是轻度认知障碍（MCI）诊断中的关键组成部分。但是，对MCI参与者的记忆意识进行检查的研究发表了矛盾的结果。对于不一致的发现的一种可能的解释可能是无视主观记忆的多维结构。目的本研究旨在评估健康和MCI参与者中的主观记忆，涉及三种主要的记忆类型：情节记忆，语义记忆和工作记忆。方法参与者为123名成人（50-90岁）。根据他们在RAVL或Mo-CA测试中的客观认知表现，将他们分为两组，即MCI组和对照组。所有参与者都填写了主观记忆问卷，评估了他们对情节，语义，和工作记忆。结果MCI参与者估计他们的语义记忆与健康对照的估计相比显着降低。相比之下，与对照组相比，MCI参与者表现出过高的情景记忆能力。在评估他们的工作记忆时，各组（MCI和健康对照组）之间没有发现显着差异。此外，对于这两个群体，皮尔逊相关性都显示出年龄和语义记忆评估之间存在显着的负相关性。对于主观的情节记忆没有发现这种相关性。讨论结果表明，尽管MCI患者对其情节记忆和工作记忆能力的认识较差，但他们对语义记忆力下降的认识显然是完整的。所以，
