Epigenetic Age Acceleration

Meaning

Epigenetic age acceleration is a clinical and biological phenomenon where an individual’s calculated DNA methylation age (DNAmAge) is significantly older than their chronological age, indicating a faster-than-average rate of biological aging. This metric serves as a powerful biomarker for increased risk of all-cause mortality, cardiovascular disease, and other age-related pathologies, reflecting the cumulative burden of lifestyle and environmental stressors on the genome. Clinicians utilize this acceleration value to identify individuals who may benefit most from aggressive intervention strategies aimed at mitigating biological decline and promoting longevity. The difference between biological and chronological age provides a tangible measure of physiological reserve and health trajectory.
