![]() ![]() 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. Scores from each test were converted to normative values (percentile scores and Z-scores) based on Mexican norms. 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). doi:10.1016/j.jalz.2012.09.Category: Parkinson's Disease: Cognitive functions Alzheimer's association recommendations for operationalizing the detection of cognitive impairment during the Medicare annual wellness visit in a primary care setting.

Lower Spanish and English MoCA cutpoints may improve diagnostic accuracy for identifying cognitive impairment in this group, highlighting the need for the creation and validation of accurate cognitive screeners for ethnoculturally and linguistically diverse older adults. ROC analyses identified ≤18.5 as the score to identify MCI or dementia using the English MoCA (65% sensitivity 77% specificity) and ≤16.5 for the Spanish MoCA (64% sensitivity 73% specificity) in this sample of older adults with cognitive concerns.Ĭurrent MoCA cutpoints were inappropriately high in a culturally/linguistically diverse urban setting, leading to a high false-positive rate. The published cutpoint ≤23 for MCI yielded a high false-positive rate (79%). Mean English MoCA average was 18.6 (SD = 4.1) versus Spanish 16.7 (SD = 4.3). Neuropsychological assessment identified 90 as cognitively normal/SCC, average MoCA 19.9 (SD = 4.1), 133 with MCI, average MoCA 16.6 (SD = 3.7), and 8 with dementia, average MoCA 10.6 (SD = 3.1). There were 231 participants, with mean age 73, 72% women, 43% Hispanic 39% Black/African American 113 (49%) completed testing in English and 118 (51%) in Spanish. ROC analyses identified optimal MoCA cutpoints for discriminating possible cognitive impairment. One-way ANOVA compared cognitive statuses. MoCA and neuropsychological measures were administered in Spanish or English, and a neuropsychologist determined cognitive status (normal with subjective cognitive concerns, mild cognitive impairment, and dementia). Participants aged ≥65 with cognitive concerns attending outpatient primary care in Bronx, NY, were recruited. We sought to examine the utility and discriminative validity of the Spanish and English MoCA versions to identify cognitive impairment among diverse community-dwelling older adults. Efficacy and validity of the MoCA for cognitive screening in ethnoculturally and linguistically diverse settings is unclear. ![]()
