NEW YORK (WABC) -- Could a simple blood test help predict a person's risk of developing Alzheimer's disease or other cognitive impairments?
That question is at the heart of a recent study which states that blood tests could, in fact, help predict a person's risk for developing the disease, years before any cognitive decline.
The major breakthrough came out of this week's Alzheimer's Association International Conference in London.
Bill Ritter interviewed Rachel Buckley, who's the lead study author and an associate professor of neurology at Harvard Medical School.
