Faster biological aging predicts lower cognitive test scores 7 years later

An analysis of the Framingham Heart Study data found that higher epigenetic aging metrics predicted lower scores on the digital Clock Drawing Test 7 years later. The strongest association was with DunedinPACE, a biomarker of the pace of biological aging. The research was published in Aging. As people age, their DNA molecules undergo specific chemical changes. These changes mainly involve the addition or removal of methyl groups at CpG sites on t…
