No, it sounds like you're thinking of a coma, though being 'brain dead' is something else entirely.

Concussion can indeed be serious business, though. A fair few rugby players in my country have died from concussion due to ignoring medical advice, by simply drinking a moderate amount of alcohol or enjoying a hot shower in the immediate aftermath of their injury.
