ABSTRACT

Introduction: It is essential to have sensitive, economical and quick cognitive screening tools for early detection of Mild Cognitive Impairment (MCI). The objective of the present study was to assess a new way of interpreting widely used screening tests, generating a new score: the CSIS (Combined Screening Interpretation Score). The CSIS considers the performance in various routine screening tests (MMSE, Clock drawing test, Short form of the Boston naming test, Phonological and Semantic fluency tests and the Frontal Assessment Battery) by summing up their gross scores in one general score.

Methods: We calculated the CSIS of 90 Hispanic older adults without dementia (40 controls and 50 patients with a diagnosis of MCI). The differences of the CSIS between the groups, and the discriminative capacity of the CSIS and each separate test were analyzed.

Results: Significant differences in the CSIS were observed between the groups, as a higher discriminative capacity of the CSIS compared to the other screening tests. A score of 86 points in the CSIS discriminates the groups with 84% sensitivity and 90% specificity.

Conclusion: It is concluded that the CSIS is a useful, simple and brief tool to assess the cognitive performance of subjects with MCI.

摘要

简介：必须具备敏感，经济和快速的认知筛查工具，以及早发现轻度认知障碍（MCI）。本研究的目的是评估一种解释广泛使用的筛查测试的新方法，从而产生一个新的分数：CSIS（联合筛查解释分数）。CSIS通过将他们的总成绩合计为一个总分来考虑各种常规筛查测试（MMSE，时钟绘图测试，波士顿命名测试的简短形式，语音和语义流利度测试以及正面评估组合）的表现。

方法：我们计算了90名无痴呆症的西班牙裔老年人（40名对照者和50名诊断为MCI的患者）的CSIS。分析了两组之间的CSIS差异，CSIS的判别能力以及每个单独的测试。

结果：两组之间在CSIS方面存在显着差异，因为CSIS的判别能力高于其他筛查测试。在CSIS中得分为86分，以84％的敏感性和90％的特异性区分了这些组。

结论：结论是CSIS是评估MCI受试者认知能力的有用，简单且简短的工具。
