1:20Now PlayingA new blood test to detect early Alzheimer's will be available to GPs from September.
The test, called pTau 217, offers a quick and reliable way to check for disease in patients showing early cognitive decline.
It measures levels of the pTau 217 protein, which signal the build‑up of toxic amyloid plaques in the brain, and is designed for people over 55.
There's still no cure for Alzheimers, but nutritional support can slow early disease, though they aren't yet subsidised. | *Subscribe and 🔔
