What exactly are researchers looking for when trying to solve the Alzheimer’s puzzle? “It depends on the researcher,” says Kevin Hascup, PhD. “Really, the tried and true biomarkers are three — amyloid, tau and neurofilament light chain, or what is known as A/T/N.” A biomarker (molecules in blood, body fluid, and tissue) helps with understanding the changes that occur with age and disease onset. Each of the three A/T/N biomarkers progress in its own way in aging and with dementia. But no matter which
