Longitudinal associations of epigenetic aging clocks with cognitive decline in diverse Hispanics/Latinos.
Abstract
Several epigenetic clocks based on DNA methylation (DNAm) have been developed to estimate an individual’s biological age. Age acceleration, the deviation of the DNAm‐estimated age from the chronological age, has been proposed as a novel biomarker to predict age‐associated conditions and life expectancy. Due to the paucity of longitudinal DNAm data, especially among diverse Hispanic/Latino adults, the association between changes in age acceleration over time and cognitive aging phenotypes has not been investigated.

Research summary
The paper investigates the relationship between epigenetic aging clocks and cognitive decline, focusing on a specific demographic that has been underrepresented in aging research. While it contributes to understanding biological aging and its implications for cognitive health, the findings are likely to be incremental rather than groundbreaking. The focus on cognitive aging, while relevant to longevity, does not directly address the root causes of aging or lifespan extension, which limits its overall impact.
