he distinction between cognitive alterations compatible

with normal aging and pathological processes in the

early stages, such as mild cognitive impairment (MCI) and

mild Alzheimer’s disease (AD), is sometimes difficult. The

aim of the present study was to propose cutoff scores for

the Brazilian version of the Montreal Cognitive Assessment

(MoCA-BR) stratified by education in order to detect MCI

and mild 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. TheMCI diagnosis was defined based on the criteria

of Petersen (2004). In turn, the diagnosis of AD was based

on the criteria of the National Institute of Neurological and

Communicative Disorders and Stroke/Alzheimer’s Disease and

Related Disorders Association (NINCDS/ADRA). 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 peoplewith cognitive impairment withmore

than 12 years of education, and scores under 21 were good

for screening those with 4– 12 years of education. Therefore,

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.

The cutoff points presented can be used to inform future work

using theMoCA-BR to screen for MCI and AD in older Brazilian

people. Future studies could focus on early detection and

treatment of cognitive dysfunctions in clinical practice.
