Your Epigenetic Age May Predict How Fast Your Grip and Memory Fade

Key Insight

This study suggests not all epigenetic age tests track real-world decline equally well.


Among about 4,000 older Americans followed for up to 12 years, those whose DNA looked biologically older lost function faster. The GrimAge clock stood out, tracking quicker decline in memory, grip strength, and walking speed. Other clocks barely showed anything, so not all biological age tests are equal. This is a correlation, not proof that a clock can tell you your future.
