CNN Testing a person’s blood for a type of protein called phosphorylated tau, or p-tau, could be used to screen for Alzheimer’s disease with “high accuracy,” even before symptoms begin to show, a new study suggests. The study involved testing blood for a key biomarker of Alzheimer’s called p-tau217, which increases at the same time...
