(WZZM) -- A new blood test could predict if a healthy person will develop Alzheimer's disease at an earlier age.
Researchers at Georgetown Medical Center developed the test. They say it can predict whether someone will get Alzheimer's within three years of taking the test with greater than 90 percent accuracy.
If the study is confirmed, diagnosing Alzheimer's in its earliest stages would give doctors the chance to design new treatments.
"The test enables the identification of high risk people," said Dr. Howard Federoff with the Georgetown University School of Medicine. "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. As many as five million Americans may have Alzheimer's Disease. Click here to learn more about Alzheimer's Disease. Click here to learn more about the blood test research.
