Accelerated Biological Aging May Increase Risk of Dementia, Stroke

Accelerated biological aging may increase risk of dementia, stroke

A hallmark of accelerated aging appears to be linked to an increased risk of dementia and stroke, a new study says.

Bidirectional relationship between epigenetic age and stroke, dementia, and late-life depression

Chronological age is an imperfect estimate of molecular aging. Epigenetic age, derived from DNA methylation data, provides a more nuanced representation of aging-related biological processes. We examine the bidirectional relationship between epigenetic age and brain health events (stroke, dementia, late-life depression) using data from 4,018 participants. Participants with a prior brain health event are 4% epigenetically older (β = 0.04, SE = 0.…

Dementia, Stroke, Depression Linked to Biological Aging Marker

(MedPage Today) -- Shorter leukocyte telomere length -- a marker of biological aging -- was tied to a higher risk of age-related brain disease, but modifiable risk factors appeared to mitigate its effect, U.K. Biobank data suggested. In a...

Scientists make a breakthrough in measuring aging through DNA

What if your body’s age wasn’t just the number of birthdays you’ve had? Scientists are now exploring a new way to track the passage of time inside your cells—by measuring how unpredictable certain patterns in your DNA become as you grow older. Researchers from the University of California, Los Angeles have introduced a fresh tool that may one day improve how we measure biological aging. Instead of just counting chemical tags on DNA like before, …
