A new technique could lead to a blood test for detecting Alzheimer’s, a US study claims.
The small trial, published in the journal Cell, used thousands of artificial molecules to “fish” for the disease.
Researchers hope to use this method to diagnose other diseases earlier, including lung and pancreatic cancers.
The Alzheimer’s Research Trust said it could result in a new test, but more research was needed.
The technique relies on the immune system’s ability to recognise foreign material.
Proteins on viruses and bacteria are recognised as alien so the body produces antibodies, and the same is true for Alzheimer’s.
So if you can test for the antibody, you can test for the disease – traditionally, however, this has been very hard to do.
