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.Īlzheimer's disease MoCA-S dementia memory disorders mild cognitive impairment neuropsychological test validation studies. The MoCA-S is valid and adequate for application in Colombia with good internal consistency, inter-observer reliability, and content validity. The MoCA-S is a valid screening tool and is useful for identifying MCI and MD in Colombia. The percentage of patients clearly labeled by the MoCA-S was 85%. 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 psychometric evaluation of the MoCA-S was appropriate. The remaining 84 participants were healthy subjects from the community. 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).
This study is the first validation in Latin America of the MoCA in Spanish (MoCA-S), which was developed in Colombia (South America).Īiming 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. 2019 23(10):1300-06.The Montreal Cognitive Assessment (MoCA) was developed as a simple screening tool for cognitive impairment.

Therefore, optimizing the diagnostic, therapeutic, and research resources aimed to address PD-CI patients not only in Mexico but also in other resource-limited countries. Screening cognitive impairment in Mexican PwP using the MoCA could benefit by adjusting the cutoff point to ≤24, considering the lower level of education in the general Mexican population. Ĭonclusion: Comprehensive neuropsychological testing cannot be substituted by global cognitive scales. The prevalence of CI was 30.8% using the neuropsychological battery as the gold standard. Results: Mean education and PD evolution years were 11.6±4.9 and 8.7±4.8, respectively.
Cognitive impairment was diagnosed according to the Movement Disorder Society Task Force criteria, and considering a Z-score of less than -1.5 either in one test of at least two different domains or in both tests from one single domain.
(2005) as a simple instrument with which to screen for mild cognitive impairment (MCI) and mild Alzheimer’s. Scores from each test were converted to normative values (percentile scores and Z-scores) based on Mexican norms. The Montreal Cognitive Assessment (MoCA) test was developed by Nasreddine et al. Cognitive assessment was carried out with the Mexican version of the MoCA (v8.3) and a comprehensive neuropsychological battery, which explored 5 cognitive domains, with 2 tests for each domain. Method: 91 Mexican PwP (60.4% males 60.3☑0.0 years-old) were included in this cross-sectional study. Nevertheless, the cutoff point for PD-CI might need adjustment considering the lower educational level in Mexico. Its Spanish version is a valid and reliable tool for Mexican elderly people. The Montreal Cognitive Assessment (MoCA) is a screening tool recommended to assess CI in PD. Neuropsychological testing is needed to classify CI subtypes, as well as to identify PwP at higher risk of developing PDD, furthermore implementing timely therapeutic strategies and improving patient care and well-being. Whereas 19–38% of PwP develop a degree of CI, up to 80% could progress to dementia (PDD). Objective: To determine an optimal cutoff point of the MoCA for cognitive impairment detection in Mexican persons with PD.īackground: Cognitive impairment (CI) is frequent in persons with Parkinson’s disease (PwP).
