To propose cutoff scores for the Brazilian version of the Montreal Cognitive Assessment (MoCA-BR) stratified by education in order to detect mild cognitive impairment (MCI) and mild Alzheimer's disease (AD) in the elderly.
A transversal study in health centers was performed on 159 elderly people with 4-12 years of education and 70 of their peers with over 12 years of schooling. The MoCA-BR cutoff scores for screening cognitive impairment were determined based on an ROC curve analysis.
The ROC curve analysis indicated that cutoff scores under 20 were good for screening elderly people with cognitive impairment with more than 12 years of education, and scores under 21 were good for screening those with 4-12 years of education.
MoCA-BR scores under 21 points (after adding 1 point to the elderly with ≤12 years of education) indicate a need to continue the diagnostic investigation with regular follow-ups.
为巴西版蒙特利尔认知评估量表（MoCA-BR）提出按教育程度分层的截断分数，以便在老年人中检测轻度认知障碍（MCI）和轻度阿尔茨海默病（AD）。
在健康中心对159名接受过4至12年教育的老年人及其70名接受过12年以上教育的同龄人进行了一项横断面研究。基于ROC曲线分析确定了用于筛查认知障碍的MoCA-BR截断分数。
ROC曲线分析表明，20分以下的截断分数有利于筛查接受过12年以上教育的认知障碍老年人，21分以下的分数有利于筛查接受过4至12年教育的老年人。
MoCA-BR分数低于21分（对受教育年限≤12年的老年人加1分后）表明需要通过定期随访继续进行诊断性调查。
