ROCHESTER, N.Y. (WHEC) — There may soon be a way to help diagnose and treat people with Alzheimer's disease with a simple blood test.

A new experimental blood test has proven to identify people with Alzheimer's versus people with no dementia or other forms of it with an 89% to 98% accuracy rate.

The current test for the disease relies on testing memory and thinking skills and is very imprecise.

Patients can also be tested with a spinal tap or brain scan, but that can be expensive and invasive. 

David Gill, the director of the Memory Center at Rochester Regional Health says this could revolutionize how doctors diagnose and treat patients.

"It's probably going to lead to a bit of a change in our definition of Alzheimer's disease,” Gill said. “Right now we have to wait until somebody is quite impaired before we can call it Alzheimer's disease, even though we know the changes that build up in the brain and cause the disease start many years before the diagnosis."

More than 5 million Americans suffer from Alzheimer's disease.
