New blood test for Alzheimer's could be new breakthrough
Researchers from the Florida campus of the Scripps Research Institute have developed a new blood test for Alzheimer's disease which could detect the condition much earlier than current methods. The test is based on the body's immune system which produces antibodies in response to proteins on viruses and bacteria and those produced in Alzheimer's disease. The team used 15,000 synthetic proteins as 'bait' to 'fish' for antibodies in blood samples taken from six patients with Alzheimer's disease, six with Parkinson's and six healthy individuals. The test proved successful in this small sample but lots more research is needed before it can be fully established.
