The MoCA is a brief useful test to diagnose mild cognitive impairment (MCI) and mild dementia (MD). To date, no Argentine cross-cultural adapted validations of the Spanish version have been reported.
To validate the MoCA in the elderly and study its usefulness in MCI and MD.
This study included 399 individuals over 60 years old evaluated in the Cognitive-Behavioral Department (2017-2018). Patients with<3 years of education, sensory disturbances, psychiatric disorders, or moderate-severe dementia were excluded. The control group comprised cognitively normal subjects. Participants were classified according to neuropsychological assessment and clinical standard criteria into Control, MCI or MD groups. A locally adapted MoCA (MOCA-A) was administered to the patients and controls.
Mean educational level was 10.34 years (SD 3.5 years). MoCA-A score differed significantly among groups (p<0.0001). MoCA-A performance correlated with educational level (r: 0.406 p<0.00001). Adopting a cut-off score ≥25 (YI=0.55), the sensitivity for MCI was 84.8% and for MD 100%, with specificity of 69.7%. When adding a single point to the score in patients with ≤12 years of education, the specificity of the test reached 81%.
The MoCA-A is an accurate reliable screening test for MCI and MD in Argentina.
蒙特利尔认知评估量表（MoCA）是一种用于诊断轻度认知障碍（MCI）和轻度痴呆（MD）的简短实用测试。迄今为止，尚未有关于西班牙语版本的阿根廷跨文化适应性验证的报道。
验证MoCA在老年人中的有效性，并研究其在MCI和MD中的实用性。
本研究纳入了399名60岁以上在认知行为科接受评估的个体（2017 - 2018年）。排除了受教育年限<3年、有感觉障碍、精神疾病或中度至重度痴呆的患者。对照组包括认知正常的受试者。参与者根据神经心理学评估和临床标准被分为对照组、MCI组或MD组。对患者和对照组进行了本地化改编的MoCA（MOCA - A）测试。
平均受教育年限为10.34年（标准差3.5年）。MoCA - A得分在各组之间存在显著差异（p<0.0001）。MoCA - A的表现与受教育水平相关（r：0.406，p<0.00001）。采用≥25分的截断分数（YI = 0.55），MCI的敏感性为84.8%，MD为100%，特异性为69.7%。对于受教育年限≤12年的患者，在得分上加1分，该测试的特异性达到81%。
在阿根廷，MoCA - A是一种用于MCI和MD的准确可靠的筛查测试。
