Currently, CTE can only be definitively diagnosed by direct tissue examination after death, including full and immunohistochemical brain analyses. The lack of in vivo techniques to show distinct biomarkers for CTE is the reason CTE cannot currently be diagnosed while a person is alive. The only known diagnosis for CTE occurs by studying the brain tissue after death. Concussions are non-structural injuries and do not result in brain bleeding, which is why most concussions cannot be seen on routine neuroimaging tests such as CT or MRI. PET tracers that bind specifically to tau protein are desired to aid diagnosis of CTE in living individuals. A putative biomarker for CTE is the presence in serum of autoantibodies against the brain.
The autoantibodies were detected in football players who experienced a large number of head hits but no concussions, suggesting that even sub-concussive episodes may be damaging to the brain. Stern, one of the scientists at the Boston University CTE Center, said in 2015 that “he expected a test to be developed within a decade that will be able to diagnose C.
