Prevalence of dementia and mild cognitive impairment in the Mexican population: evidence from Mex-Cog, a harmonized cognitive assessment protocol study.
Article in The journals of gerontology. Series B, Psychological sciences and social sciences, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesThis study aimed to estimate the prevalence of dementia and mild cognitive impairment (MCI) in Mexico and establish sociodemographic, contextual, and health predictors leveraging the first wave of the Mexican Cognitive Aging Ancillary Study (Mex-Cog), a subsample of the Mexican Health and Aging Study.
methodsData came from the 2016 wave of Mex-Cog. The analytic sample included 1,629 participants aged 60 and older who completed a comprehensive cognitive battery and informant questionnaire. We employed a robust normative approach to classify cognitive impairment and developed an algorithmic classification of MCI/dementia based on standard research criteria. Prevalence rates used nationally-representative sampling weights.
resultsWe estimated the prevalence of dementia at 6.7% [95% confidence interval (CI): 5.4-8.0] and MCI at 10% (95% CI: 8.7-11.7). Older age, lower education, living in rural areas, having a history of stroke, and heart attack were associated with higher odds of dementia. Mild cognitive impairment was associated with older age, female sex, lower education, rural residence, and lack of health insurance. DISCUSSION: Leveraging the nationally-representative and comprehensive cognitive data in Mex-Cog, an algorithm-derived classification of dementia and MCI provided the prevalence of dementia and MCI in Mexico. Besides the association with cerebrovascular and cardiovascular disease, the effect of education, rural residence, and lack of health insurance suggests an unequal burden of MCI and dementia among the aging Mexican population.
