dementia

Are men who played high school football in Minnesota in the twenty-five years after World War II at increased risk of later developing dementia, Parkinson's or ALS compared with non-football playing high school males? Not according to two studies by researchers at the Mayo Clinic.

Concussions, and even lesser subconcussive head trauma, may speed up the brain's natural aging process says a new study which found changes in gait, balance, and in the brain's electrical activity in areas measuring attention and impulse control in otherwise healthy college students with a history of concussion.
