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.

The conclusion that chronic traumatic encephalopathy (CTE) is caused by concussions and repetitive subconcussive brain trauma is scientifically premature, say an increasing number of researchers.
