As college football bowl season begins, a concussion warning

In July, a Journal of the American Medical Association report that the brains of 110 of 111 deceased NFL players showed evidence of chronic traumatic encephalopathy (CTE) — an incurable condition that leads to dementia, mental instability and depression — made national headlines. But what should have gotten more attention was the finding that the brains of 48 of 53 deceased college football players showed CTE. There are more than 750 colleges with football programs versus 30 NFL teams.
