A new blood test called “MethylCog” uses 29 DNA methylation markers from a blood sample to predict general cognitive ability, and was shown to help distinguish people with mild cognitive impairment (MCI) from healthy individuals, improving detection accuracy beyond age and sex alone. This blood-based biomarker offers a scalable and easy-to-use tool that could help identify those at risk for dementia, especially in settings where direct cognitive testing is not possible.

This improvement makes it easier for doctors to measure important energy molecules in the liver, helping them better diagnose and monitor liver diseases.

This study highlights the urgent need for better care coordination between cardiologists and oncologists to improve survival for patients battling both heart disease and cancer.
