A surprising blood protein pattern may reveal Alzheimer’s

Alzheimer's disease affects an estimated 7.2 million Americans age 65 and older, according to the Alzheimer's Association. Current diagnostic tests typically measure the levels of two proteins -- amyloid beta (Aβ) and phosphorylated tau (p-tau) -- in blood or spinal fluid. While these biomarkers are widely used, they may not fully reflect the earliest biological changes that occur as the disease develops.
