ATLANTA — Emory Healthcare is working to implement a test used to detect Alzheimer’s disease and other types of dementia. The clock-drawing test, which is typically part of a larger Mini-Cog test, is ...

A digital version of the classic clock-drawing test can accurately identify early Alzheimer's disease (AD) pathology in asymptomatic patients in less than 5 minutes, new research shows. Investigators ...

These days, you can order up a test to find out your biological age, an estimate of how quickly or slowly you're aging compared to your peers. It's based on an analysis of modifications in your DNA. I ...

Daily cycles in virtually every aspect of our physiology are driven by biological (or circadian) clocks in our cells. A team of interdisciplinary scientists has now reconstituted the circadian clock ...

Daily cycles in virtually every aspect of our physiology are driven by biological clocks (also called circadian clocks) in our cells. The cyclical interactions of clock proteins keep the biological ...
