A concussion, also called a mild traumatic brain injury, is a head injury caused by the brain being shaken around inside the skull after a direct blow to the head, or a sudden jerking of the head or neck when the body is hit. You don't have to pass out (lose consciousness) to have a concussion. Some people will have symptoms of a concussion, such as passing out or forgetting what happened right before the injury, but others won't.
Common causes of a concussion/mild brain injury are falls, sports, physical assaults, and motor vehicle collisions.
Sometimes an injury to your brain can be more serious. Signs of a more serious injury such as bleeding and /or swelling in the brain can be seen in the
first 24 to 48 hours.
Call 911 or go to the hospital right away for any of these possible life threatening issues:

See a doctor if your symptoms are affecting your everyday activities. Remember that letting yourself get too tired can make your symptoms worse. Listen to your body: if doing a certain activity increases your symptoms, take a break from that activity. Build up the amount of time you do a particular activity and stay under the threshold of symptoms.
