(Refeed) Brain Trauma

Knocks to the head may seem funny in cartoons, sports replays, and YouTube videos, but even minor head injuries often lead to serious concussions. A concussion may leave no trace on a conventional MRI scan yet cause permanent memory loss, attention problems, and depression. NOVA scienceNOW investigates promising new leads in understanding this puzzling condition, which affects millions of people in the U.S., including many high-school and college athletes who suffer concussions yet are encouraged to return to the playing field.
