背景：主观记忆抱怨（SMCs）是老年人的一种常见特征。对记忆的主观认识依赖于客观认识。本研究的目的是检验主观记忆认知（即，方法：对181例正常对照组（NC）和38例轻度认知功能障碍（MCI）患者共219例进行标准化、综合性的临床评定和神经心理学评定。结果：2 × 2双因素方差分析结果表明，认知状态（NC、MCI）与记忆功能之间存在显著的交互作用，认知功能与言语记忆、视觉空间记忆、注意力、流畅性和语言功能之间存在显著的交互作用。与没有SMC的NC相比，具有SMC的NC在言语记忆和视觉空间记忆方面表现出显着较低的表现。相反，在MCI组中没有观察到效果。结论：主观认知（即，SMC）和客观认知（即，认知状态）对老年人记忆表现的影响。SMCs对记忆成绩的影响应结合老年人的客观认知状况来解释。
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 x 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.
