Alzheimer’s Research: Progressing towards a tau blood test for Alzheimer’s disease

Alzheimer’s Research UK | July 2020 | Progressing towards a tau blood test for Alzheimer’s disease

  • Four new studies presented at the Alzheimer’s Association International Conference (AAIC) and two published papers show that levels of tau, a hallmark protein of Alzheimer’s disease, in the blood could be used to detect the disease
  • The research focuses on a specific form of tau, p-tau217
  • The new data suggests blood levels of p-tau217 can predict the development of Alzheimer’s disease before symptoms appear, track well with levels of tau in the brain and distinguish Alzheimer’s from other diseases that cause dementia

Researchers from both the US and Europe have presented data that indicates levels of a specific form of tau, one of the hallmark proteins of Alzheimer’s disease, can be measured in blood to detect the disease, even before symptoms appear. 

Full details of the studies are available from Alzheimer’s Research UK
