Researchers have discovered a first-of-its-kind blood test for Alzheimer's disease that can predict - with 90 percent accuracy - if a healthy person will develop this cruel disease within three years. Dr. Howard Federoff, the Executive Vice President for Health Sciences at Georgetown University Medical Center and Executive Dean of Georgetown University School of Medicine, led the team and briefed us on why his biomarker study is a potential game-changer.

This call was made possible by the generous support of the Zickler Family Foundation.
