Scientists say they are using a blood test to find out if a patient is likely to develop Alzheimer's disease. Although the 87-percent accuracy needs to be improved, the development is getting attention world-wide. UT-Health Medical Center neurology professor Dr. Claudio Soto says the early diagnosis is very important.
"If you can have a method to know when people are going to develop the disease,” Soto says, “before substantial damage to the brain has occurred, that can be very beneficial.”
The current problem is, Alzheimer's is diagnosed after the brain has been damaged in most cases.
“If you can get people to develop the disease five years later than they normally would,” he says, “that is a huge improvement.”
