Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <sec id="gps4199-sec-0001" sec-type="section"> <title>Objective</title> <p>The Montreal Cognitive Assessment (MoCA) was developed as a simple screening tool for cognitive impairment. This study is the first validation in Latin America of the MoCA in Spanish (MoCA‐S), which was developed in Colombia (South America).</p> </sec> <sec id="gps4199-sec-0002" sec-type="section"> <title>Methods</title> <p>Aiming to perform the first validation of the MoCA‐S, we developed a study of concordance by conformity to assess the MoCA‐S compared with diagnostic consensus by interdisciplinary assessment in the Memory Clinic (the best diagnostic method available) and to evaluate the psychometric properties of the MoCA‐S. A total of 193 subjects were evaluated, 109 of whom were patients, including 26 who met the mild cognitive impairment (MCI) clinical criteria, based on neuropsychological testing, and 83 who had mild dementia (MD). The remaining 84 participants were healthy subjects from the community.</p> </sec> <sec id="gps4199-sec-0003" sec-type="section"> <title>Results</title> <p>The psychometric evaluation of the MoCA‐S was appropriate. Using a cutoff score of ≥23, the MoCA had sensitivities of 76.0% to detect MCI and 92.7% to detect MD and a specificity of 79.8%. The percentage of patients clearly labeled by the MoCA‐S was 85%.</p> </sec> <sec id="gps4199-sec-0004" sec-type="section"> <title>Conclusion</title> <p>The MoCA‐S is a valid screening tool and is useful for identifying MCI and MD in Colombia. The MoCA‐S is valid and adequate for application in Colombia with good internal consistency, inter‐observer reliability, and content validity. However, the average educational level was high in this study; thus, caution should be exercised when extrapolating these results to individuals with lower educational levels.
