Concussions in Football
A concussion is a type of traumatic brain injury that is caused by a blow to the head or body, a fall, or another injury that jars or shakes the brain inside the skull. Although there may be cuts or bruises on the head or face, there may be no other visible signs of a brain injury. Some people will have obvious symptoms of a concussion, such as passing out or forgetting what happened right before the injury. The amnesia, which may or may not be preceded by a loss of consciousness, almost always involves the loss of memory of the impact that caused the concussion. But other people won't. With rest, most people fully recover from a concussion. Some people recover within a few hours. Other people take a few weeks to recover.
Today we worry more about high-impact strikes to the head than about repetitive blows of moderate intensity. We think the only players who suffer brain injuries during collisions are the ones who later look dazed, or who can't keep their balance, or who suffer from slurred speech and vision. There are about 1 million high-school football players in any given year in the United States. There are also a lot of reported concussions, and probably about as many that go unreported because fans, coaches, and parents don't want a star athlete pulled from a game. But among the supposedly injury-free remainder, the Purdue researchers believe tens of thousands of athletes routinely suffer serious brain injuries from high-impact collisions intrinsic to the game.
When it comes to concussions there are three different grades. Grade one is simply remove from activity and examine immediately and if okay may return if no symptoms reoccur within 20 minutes. Then you move to grade two which is remove from activity and do not let the athlete to return. Athlete may return after a full week with no symptoms showing. Grade three be transported to the nearest hospital and my return after two weeks without symptoms. So as you see concussions...
