摘要

目的研究病理性脑老化对患者信息回忆和识别记忆的影响。因此,它们提供了记忆缺陷的不完整图像,并且没有考虑与识别记忆相关的其他因素,如识别判别性(RD)和反应偏差(RB)。因此,本研究旨在通过设拉子语言学习测试(SVLT)与健康同龄人比较,探讨遗忘性轻度认知障碍(MCI)和阿尔茨海默病对RD和RB的影响。方法与材料本描述性横断面研究于2021年在伊朗设拉子对190名年龄在60-89岁的患有遗忘性轻度认知损伤、阿尔茨海默病和正常记忆的老年人进行了研究。数据收集工具为SVLT和简易精神状态检查。数据分析采用SPSS软件19版,采用描述性统计(No.;(Mean±SD)和分析检验(ANOVA和Scheffe检验)。显著性水平设为0.05。结果遗忘型轻度认知损伤和阿尔茨海默病患者的识别记忆能力得分显著低于健康老年人(P<0.001)。他们在RD域(全局、语义、源和新)的得分也较低,假阳性错误较多(P<0.001)。在RB中,阿尔茨海默病患者的得分明显高于健忘MCI和正常记忆的老年人(P<0.001)。结论研究遗忘性轻度认知损伤患者的识别记忆表现(RB和RD)可为预测阿尔茨海默病前驱期提供有用信息。

Recognition Discriminability and Response Bias in the Shiraz Verbal Learning Test Among Older People With Amnestic Mild Cognitive Impairment, Alzheimer's Disease, and Memory Normal
Objectives Most studies have investigated the effect of pathological aging brain on information recall and recognition memory of patients by using yes-no procedures. For this reason, they provide an incomplete picture of memory defect, and other factors related to recognition memory such as recognition discriminability (RD) and response bias (RB) are not taken into consideration. In this regard, present study aims to examine the effect of amnestic mild cognitive impairment (MCI) and Alzheimer’s disease on RD and RB using the Shiraz verbal learning test (SVLT) compared to healthy peers. Methods & Materials This descriptive cross-sectional study was conducted on 190 eligible older people aged 60-89 years with amnestic MCI, Alzheimer’s disease, and normal memory in Shiraz, Iran, in 2021. The data collection tools were SVLT and mini-mental status examination. Data analysis was done in SPSS software, version 19 using descriptive statistics (No., Mean±SD) and analytical tests (ANOVA and Scheffe’s test). The significance level was set at 0.05. Results The patients with amnestic MCI and Alzheimer’s disease had significantly lower scores than the healthy older people in recognition memory performance (P<0.001). They also had lower scores and more false-positive errors in RD domains (global, semantic, source, and new) (P<0.001). in RB, the patients with Alzheimer’s disease had significantly higher scores than older people with amnestic MCI and normal memory (P<0.001). Conclusion The study of recognition memory performance (RB and RD) in patients with amnestic MCI can provide useful information to predict Alzheimer’s disease in the prodromal stage.
