摘要
在这项前瞻性纵向研究中,在3年期间进行了大样本的遗忘型轻度认知功能障碍患者,我们的研究最近提出的建议,从轻度认知功能障碍患者到阿尔茨海默病患者在长期记忆测试中基线未矫正得到的分数比校正年龄和教育矫正评分在预测更可靠。实验样本包括270例遗忘型轻度认知功能障碍患者,他们经历了在基线和随访的大量的神经学和神经心理学检查,此进程进行至少3年。在后续的80例患者已转换为明显的老年痴呆症。原数据,校正年龄,教育矫正,充分矫正,RAVLT即时和延迟回忆的预测能力得分由ROC曲线下面积(AUCs)检查相比,所有这些成绩评估(原数据或校正)评分达到更好的可靠性预测转化为痴呆。条件(aMCI的稳定与转换)进行了分析评估比值比的校正和RAVLT即时和延迟回忆得分logistic回归导致裸眼。即使在即时和延迟回忆火箭“原成绩普遍高于其他各个校正分数,这些差异没有达到统计学意义的水平,不支持的说法,未经调整的测试成绩优于年龄和教育矫正评分预测进展从轻度认知功能障碍患者到阿尔茨海默病患者。

摘要: In this prospective longitudinal study, conducted in a large sample of amnestic MCI patients over a three-year period, we investigated the recently advanced proposal that unadjusted test scores obtained at baseline on long-term memory tests are more reliable than age- and education-corrected scores in predicting progression from aMCI to AD. Our experimental sample consisted of 270 aMCI patients who underwent extensive neurological and neuropsychological examinations both at baseline and at the follow-up, conducted at least 3 years later. At the follow-up 80 patients had converted to overt dementia. The predictive capacity of raw, age-corrected, education-corrected and fully corrected scores on RAVLT immediate and delayed recall was compared by examining the area under the ROC curves (AUCs) of all of these scores to assess which (raw or corrected) scores achieves the better reliability in predicting conversion to dementia. The condition (aMCI stable vs converted) was analyzed to assess the odds ratios resulting from a logistic regression on the corrected and uncorrected scores of RAVLT immediate and delayed recall. Even if both in immediate and in delayed recall the ROCs of ‘raw scores’ were generally higher than the other ROCs on corrected scores, these differences did not reach the level of statistical significance, failing to support the claim that unadjusted test scores are superior to age- and education-corrected scores in predicting progression from aMCI to AD.
