What is a concussion?
A concussion is a brain injury caused by a bump or blow to the head or body. A concussion occurs when the brain is violently rocked back and forth or twisted in the skull. It does not have to involve a loss of consciousness. All concussions are serious.
Signs and Symptoms
A concussion may have multiple symptoms that may appear immediately after the injury. Other symptoms may take several days or weeks to develop. Concussion symptoms may last a few days to several months. If you have a blow or bump to the head, look for these signs and symptoms of a concussion:
