Cumulative effects of high school football and CTE (study)

This report echoes threads that was brought up in the hockey story posted yesterday. Be sure to watch this episode on PBS of Purdue University's study on chronic traumatic encephalopathy (CTE) for two high school football teams. The researchers used accelerometers in the helmets to measure cumulative g-force effects from collisions.

Of the 31 times that the researches brought in non-concussed players to do neurocognitive testing, 17 produced impaired scores. "That's 17 players who were not expected to be impaired," said Tom Talavage, a Purdue associate professor of biomedical engineering and electrical and computer engineering.
The fMRI data has backed up the results from the first season as well, in that the pattern of brain activity in impaired players changes when they are asked to do a task that requires mental focus.
