CTE: Is Media Narrative Ahead Of The Science?

The prevailing media narrative is that concussions or repetitive subconcussive blows "cause" chronic traumatic encephalopthy (CTE) and that there is a proven link between the two. It thus may come as a surprise that, despite widespread media coverage and speculation regarding the late-life or post-retirement risks of cognitive impairment in athletes who engaged in sports involving repetitive trauma, there has been very little in the way of peer-reviewed  literature to support that conclusion, leading many respected concussion researchers to view it as "scientifically premature."

Can Brain Scan Identify Signs of C.T.E.?

Using a sophisticated brain scan, researchers at UCLA have for the first time identified in living patients the telltale signs of chronic traumatic encephalopathy. While the results are preliminary, the study opens up the possibility of using the scans to develop strategies to prevent C.T.E. and provide treatment for those who have it.
