Accuracy and Psychometric Properties of the Brazilian Version of the Montreal Cognitive Assessment as a Brief Screening Tool for Mild Cognitive Impairment and Alzheimer's Disease in the Initial Stages in the Elderly.

Objective: To evaluate the applicability and the psychometric properties of Montreal Cognitive Assessment Brazilian Version (MoCA-BR) in the elderly, as well as comparing its accuracy as a tracking test for mild cognitive impairment (MCI) and mild Alzheimer's disease (AD) with the accuracy of Mini-Mental State Examination (MMSE).

Method: A transversal study was performed in 4 reference medical centers that care for the elderly. In all, 229 elderly participated in the study.

Optimal Cutoff Scores for Dementia and Mild Cognitive Impairment in the Brazilian Version of the Montreal Cognitive Assessment among the Elderly.

Objective: 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.

Method: 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.

Influence of Age and Education on the Performance of Elderly in the Brazilian Version of the Montreal Cognitive Assessment Battery.

Aims: To provide normative data for the Brazilian version of the Montreal Cognitive Assessment (MoCA-BR) and to measure the effect of sociodemographic variables on the cognitive performance of cognitively healthy elderly people.

Methods: A sample of 110 cognitively healthy individuals, aged over 65 years, with at least 4 years of schooling were recruited from 3 health care centers for the elderly in Recife, Brazil. The cognitive performance was assessed using MoCA-BR.
