MCI is recognized as a high\u2010risk state for Alzheimer's disease. The aim of the present study is to examine the reliability and validity of the Brazilian version of the MoCA test (MoCA\u2010BR) in a sample of older individuals with at least 4\u2009years of education.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The MoCA\u2010BR was administered to 112 older adults who were classified into three diagnostic groups according to their cognitive state (Alzheimer's disease, <jats:italic>n<\/jats:italic>\u2009=\u200928; MCI, <jats:italic>n<\/jats:italic>\u2009=\u200943; normal controls, <jats:italic>n<\/jats:italic>\u2009=\u200941). This procedure was based on clinical and neuropsychological data. The performance in the MoCA\u2010BR was compared with the Mini\u2010mental state examination (MMSE) and the Cambridge Cognitive Examination. Diagnostic accuracy was examined with the receiver operating characteristic (ROC) curve analyses.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Cronbach's alpha for the MoCA\u2010BR was 0.75. Temporal stability (retesting after 3\u2009months) using intraclass correlation coefficient was 0.75 (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). The sensitivity and specificity of the MoCA\u2010BR for MCI were 81% and 77%, respectively, with a cut\u2010off score of 25 points. The area under the ROC curve for predicting MCI was 0.82\u2009\u00b1\u20090.06.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The present results indicate that the MoCA\u2010BR maintains its core diagnostic properties rendering it a valid and reliable tool for the screening of MCI among older individuals with at least 4\u2009years of education.
