[O5–07–01]: THE RELATIONSHIP BETWEEN REPETITIVE HEAD IMPACT EXPOSURE AND CHRONIC TRAUMATIC ENCEPHALOPATHY IN AMERICAN FOOTBALL PLAYERS

Chronic traumatic encephalopathy (CTE) is a progressive neurodegenerative disease associated with exposure to repetitive head impacts (RHI), including American football. Although most pathologically confirmed cases of CTE had a history of RHI, how exposure relates to neuropathology is not known. We hypothesized that as cumulative RHI exposure increased, CTE risk would correspondingly increase. In…
