-
A new blood test can predict the onset of Alzheimer’s symptoms within three to four years
-
Instead of testing for beta-amyloid — which requires PET scans — researchers can measure a protein in the plasma, called p-tau217, according to findings published in the journal Nature
-
The test has “the potential to predict symptom onset accurately enough that we could use it in individual clinical care”
A new blood test can predict when symptoms of Alzheimer’s disease may start — helping those affected begin preventative treatment more quickly.
Researchers found that a single blood test measuring p-tau217 — a protein in the plasma — can help them gauge when a patient will start to show symptoms of Alzheimer’s disease.
While protein called beta-amyloid is believed to be a cause of the progressive…
