Neuropsychological functioning and recovery after mild head injury in collegiate athletes.
OBJECTIVE This study prospect ively examined neuropsychological functioning in 2300 collegiate football players from 10 National Collegiate Athletic Association Division A universities . The study was design ed to determine the presence and duration of neuropsychological symptoms after mild head injury .
