Alzheimer's Blood Test, a Step Closer

Researchers say it's 87% accurate at predicting disease.

British scientists are working on a blood test  for Alzheimer's disease. Researchers at Kings College London say they've found a set of 10 proteins in the blood that can determine the onset of Alzheimer's before a patient has symptoms.

They say when they analyzed blood samples from more than 1,000 people, they were able to predict with 87 percent accuracy whether people with mild memory and thinking problems would develop Alzheimer's within a year.
 
Scientists hope their findings eventually lead to patients being put on drugs early to delay or even stop the disease. However, over the past 15 years, more than 100 experimental Alzheimer's drugs have failed in trial.
