Abstract

BACKGROUND

Subjective memory complaint (SMCs) is a common trait amongst older population. The subjective cognition about their memory could depend on objective cognition. The aim of the current study was to examine the interaction between subjective memory cognition (i.e., SMC) and objective cognition on cognitive functions in participants from older generation.

METHODS

A total of 219 patients, 181 normal control (NC) patients and 38 patients with mild cognitive impairment (MCI), were examined through standardized and comprehensive clinical evaluation and neuropsychological assessment. The Subjective Memory Complaints Questionnaire was used to assess SMCs along with five cognitive tasks were used to evaluate cognitive decline over following areas: verbal memory, visuospatial memory, attention, fluency, and language.

RESULTS

The results of 2 × 2 two-way analysis of variance (ANOVA) showed that there were significant interactions between SMCs and cognitive status (NC, MCI) on memory performances. NC with SMCs showed significantly lower performance in verbal memory and visuospatial memory compared to NCs without SMCs. Conversely, no effect was observed in the MCI group.

CONCLUSION

There are interactions between subjective cognition (i.e., SMC) and objective cognition (i.e., cognitive status) on memory performances in older adults. The roles of SMCs on memory performances should be interpreted with older adults' objective cognitive status.

摘要

背景

主观记忆抱怨(SMCs)是老年人群体中常见的特征。他们对记忆的主观认知可能取决于客观认知。本研究的目的是检查老年人参与者的主观记忆认知(即 SMC)与客观认知之间对认知功能的相互作用。

方法

共有 219 名患者,181 名正常对照组(NC)患者和 38 名轻度认知障碍(MCI)患者,通过标准化和全面的临床评估和神经心理学评估进行检查。使用主观记忆抱怨问卷评估 SMC,同时使用五项认知任务评估以下领域的认知下降:言语记忆、视空间记忆、注意力、流畅性和语言。

结果

2×2 双向方差分析(ANOVA)的结果表明,SMCs 和认知状态(NC、MCI)之间存在显著的交互作用对记忆表现。与无 SMC 的 NC 相比,有 SMC 的 NC 在言语记忆和视空间记忆方面的表现明显较差。相反,在 MCI 组中没有观察到这种影响。

结论

在老年人的记忆表现中,主观认知(即 SMC)和客观认知(即认知状态)之间存在相互作用。应该根据老年人的客观认知状态来解释 SMCs 对记忆表现的作用。
