Epigenetic Aging Signal Is Linked to Brain Changes Associated With Dementia Risk
Two people can be the same chronological age and yet differ considerably in how quickly their bodies appear to be aging. Scientists have developed “epigenetic clocks” that use chemical changes to DNA to estimate aspects of biological aging. But whether an older biological age measured in blood also means that the brain is aging faster has remained unclear. A research paper published in Volume 18 of Aging titled “Association of epigenetic age acceleration with MRI biomarkers of aging and Alzheimer’s disease neurodegeneration,” investigated that question in 1,196 older women. The study was led…
