Promising new research indicates a simple blood test to diagnose Alzheimer's disease may be on the horizon.
According to CNN, researchers have developed a blood test to detect the tau protein, which is one of the hallmark signs of Alzheimer's.
Their study found the test was as accurate as a spinal tap or a positron emission tomography (PET) scan, which are the current gold standards of diagnosis.
Experts say the day may come in the next few years when a health care provider can do a blood test for Alzheimer's right in the doctor's office.
Not only would it be a game-changer for individuals, it could also help to identify the right people for clinical drug trials.
