Normative data for the Mini-Mental State Examination, the Free and Cued Selective Reminding Test and the Isaacs Set Test for an older adult Mexican population: The Coyoacán Cohort Study

Abstract

The Mini-Mental State Examination (MMSE), the Free and Cued Selective Reminding Test (FCSRT), and the Isaacs Set Test (IST) are useful instruments in the neuropsychological assessment of older individuals. Several versions of these tests exist in Spanish but normative data specifically set up for Mexican older adult population are missing although Mexico is the country containing the largest population of Spanish speakers and is undergoing a demographic transition with its aging population. Therefore, the aim of the present work was to produce age, educational level, and gender-adjusted normative scores for these tests for the population of older adults living in Mexico. Methods: Data were collected from a sample of 1047 subjects aged 70 years and over who participated in the Coyoacán cohort study, a population-based cohort study conducted in Mexico City. Results: Normative scores, presented in percentiles, were calculated according to age (70–79 and 80 years and over), educational level (0 years of schooling vs. 1–5 years of schooling vs. 6 and more years of schooling), and gender. Conclusion: This work provides norms for the MMSE, the FCSRT, and the IST which should be useful in clinical practice and helpful to better interpret the performances of Mexican older people consulting for memory troubles.
