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 can also occur when the head and upper body are violently shaken. These 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 sport, such as football. But every concussion injures your brain to some extent. This injury needs time and rest to heal properly. Most concussive traumatic brain injuries are mild, and people usually recover fully.
WHAT IS A CONCUSSION?
Concussions are a surprisingly common occurrence in sports. High school athletes suffer thousands of concussions every year, most often in football, ice hockey, and soccer. Concussions do not always involve being "knocked out," or a loss of consciousness. A concussion occurs whenever a child's mental status changes as a result of trauma (usually a blow to the head). A child who shows signs of mental confusion or is "dinged" by a blow to the head has suffered a concussion.
WHAT HAPPENS AFTER A SPORTS-RELATED CONCUSSION
Sports-related concussions often result in mental and physical symptoms (e.g., inability to concentrate, forgetfulness, headache, fatigue, dizziness). For many athletes, the symptoms disappear after about 10 days, and they typically do not last more than several months. In some cases, though, concussions lead to persistent complaints of physical, mental, emotional, and behavioral symptoms, sometimes referred to as post-concussion syndrome. We do not know whether persistent post-concussive symptoms result from primarily medical or psychological causes. In rare cases, when repeated concussions occur over a brief interval, athletes may suffer from second impact syndrome, a
