What is a Concussion
A concussion is a traumatic brain injury that alters the way your brain functions. Effects are usually temporary, but can include problems with concentration, memory, judgment, balance and coordination. Although concussions are usually caused by a blow to the head, they can also occur when the head and upper body are violently shaken. Some injuries can cause a loss of consciousness, but 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 or collision sport. However, every concussion injures your brain to some extent. This injury needs time and rest to heal properly. Luckily, most concussive traumatic brain injuries are mild, and people usually recover fully.
