New blood test could diagnose Alzheimer's disease

Posted: Updated:
WASHINGTON, D.C. (WKOW) -- In a first-of-its-kind study, researchers have developed a blood test to diagnose Alzheimer's disease.

The researchers, led by a team from Georgetown medical center, say their test can predict with greater than 90% accuracy -- if a healthy person will develop Alzheimer's within three years.
   
The test could also be used to design new treatments.

Dr. Howard Federoff of the Georgetown University School of Medicine says, "The test enables the identification of high risk people, you could then do the research to ask do we now have a new therapy that could arise and delay symptom onset."

The test could be ready for clinical trials in a few years.
