Brain scans performed on five former NFL players revealed images of the protein that causes football-related brain damage -- the first time researchers have identified signs of the crippling disease in living players.Researchers who conducted the pilot study at UCLA described the findings as a significant step toward being able to diagnose the disease known as Chronic Traumatic Encephalopathy, or CTE, in living patients."I've been saying that identifying CTE in a living person is the Holy Grail for this disease and for us to be able make advances in treatment," said Dr. Julian Bailes, a Chicago neurosurgeon and one of the study's co-authors. "It's not definitive and there's a lot we still need to discover to help these people, but it's very compelling. It's a new discovery."
