Researchers Developing Blood Testing for Alzheimer's Disease

July 11, 2014

More than 5 million Americans are living with Alzheimer's, but British researchers say they may have made an important step forward in developing a test that predicts the fatal disease.

Researchers at King's College in London say they've developed a blood test that might detect Alzheimer's disease.

The test looks at ten proteins in the blood that could reveal early changes in the brain related to the disease even before a patient has symptoms.

Alzheimer's advocates say this is a step in the right direction.

"Very positive news. It's progress. It gives us hope that we can come up with a simple blood test that would help indicate if someone is at risk of Alzheimer’s,” says Sue Friedman, Alzheimer’s Association. “Of course the next step is we need that intervention, that treatment that will allow us to stop that risk from becoming Alzheimer’s disease."

Over the past 15 years, more than 100 experimental Alzheimer's drugs have failed in trial.
