摘要

诱导回忆法是阿尔茨海默病(AD)中常见的 "海马型 "遗忘症的一种。对诱导回忆法在阿尔茨海默病中的有效性进行的研究通常是在研究环境中进行的。类别提示记忆测试(CCMT-48)测量的是在编码和获得过程中使用相同类别进行学习/记忆的情况。本研究旨在调查来自记忆诊所的轻度注意力缺失症患者(N = 77)在 CCMT-48 中出现障碍的频率。我们采用以病例为导向的方法,将个人观察到的分数与基于回归常模数据得出的预期分数进行比较。我们还调查了轻度 AD 患者和路易体痴呆患者(DLB)(90 人)的 CCMT-48 表现是否存在差异。结果显示,在低于第 10 百分位数估计值(受损:AD 88%;DLB 69%)和第 5 百分位数估计值(受损:AD 82%;DLB 53%)的分数中,AD 组受损的频率明显高于 DLB 组。总之,在记忆诊所的环境中,基于图片的诱导回忆测试在注意力缺失症患者中出现障碍的频率非常高(灵敏度非常高)。然而,特异性并不理想,因为在注意力缺陷和检索策略不佳的 DLB 患者中也经常出现记忆障碍。

Impaired performances on the category cued memory test in mild Alzheimer's disease and dementia with Lewy bodies: A comparative validity study.

Cued recall taps amnesia of "the hippocampal type" as typically found in Alzheimer's disease (AD). Studies investigating the validity of cued recall measures in AD have typically been conducted in research settings. The Category Cued Memory Test (CCMT-48) measures learning/memory using the same categories during encoding and acquisition. The aim of this study was to investigate how frequently impairments were found on the CCMT-48 mild AD patients from a memory clinic (N = 77). We used a case-oriented approach where individually observed scores were compared to expected scores derived from regressions-based normative data. We also investigated if CCMT-48 performances differed in patients with mild AD and Dementia with Lewy Bodies (DLB) (N = 90). The results showed a significantly higher frequency of impairment in the AD group as compared to the DLB group for scores below 10th percentile-estimate (impaired: AD 88%; DLB 69%) and 5th percentile-estimate (impaired: AD 82%; DLB 53%). In conclusion, a very high frequency of impairment of a picture-based cued recall test in AD patients (very high sensitivity) in a memory clinic setting. However, specificity is not optimal since impairments also frequently occurred in DLB where memory problems could be assumed to be part of attentional deficits and poor retrieval strategies.
