The Centers for Disease Control and Prevention estimates that as many as 3.9 million sports-related and recreation-related concussions occur in the U.S. each year. And, that number may even be higher, because many more concussions are not diagnosed correctly.
Even with all the recent attention on concussions, how much do people really know about how to spot a concussion, what to do about it, and how they are treated? Many people don’t know how a concussion is caused.
A concussion is a traumatic brain injury that alters the way your brain functions. Effects are usually temporary, but can include headaches and problems with concentration, memory, balance and coordination. Although concussions usually are caused by a blow to the head, they also can occur when the head and upper body are violently shaken. These injuries can cause a loss of consciousness; however, most concussions do not. Because of this, some people have concussions and don't realize it. Concussions are common, particularly if you play a contact sport.
