Key Highlights
•
A new blood-based DNA methylation test called MethylCog was developed to measure general cognitive ability, potentially offering a scalable tool for early detection of mild cognitive impairment and dementia risk.

•
The MethylCog score explained about 11% of cognitive variation beyond age and sex and improved the discrimination of mild cognitive impairment, proving its potential as a blood biomarker where cognitive testing isn’t available.
