A concussion is a change in brain function caused by an injury to the head. It occurs when a blow to the head causes shaking, jarring, stretching, swelling, or tearing of brain tissue and delicate nerve fibers. If you suspect a concussion, seek medical attention immediately. You may have the symptoms of a concussion for several days after the injury.
Treatment consists mainly of observation and rest.
After you leave the medical office, you need to be observed by your family or friends at home for the next 8 to 12 hours. When you are sleeping, someone should wake you up and check you every 2 to 4 hours. If you are stable and recovering during the next 24 hours, you should rest for an additional day or two. As your symptoms go away, you can begin to go back to your usual daily routine. However, you should stay away from any activities that would risk reinjury.
