Symptoms of a head injury can occur right away. Or symptoms develop slowly over several hours or days. Even if the skull is not fractured, the brain can bang against the inside of the skull and be bruised. The head may look fine, but problems could result from bleeding or swelling inside the skull.
In any serious head trauma, the spinal cord is also likely to be injured.
Some head injuries cause changes in brain function. This is called a traumatic brain injury. Concussion is a mild traumatic brain injury. Symptoms of a concussion can range from mild to severe.

Friends or family may need to keep an eye on adults who have been injured after they are released from the emergency room or office. If the person is an athlete, follow the health care provider's instructions about when the person can return to sports.
Parents or caregivers of children will need to learn how to keep an eye on the child after a head injury. Follow the health care provider's instructions on when the child can go back to being active and playing sports.
After even a mild concussion do not do activities that can cause further head injury. Avoid tasks that require concentration or complicated thinking. These include reading, homework, preparing reports, and other kinds of brain stimulation. Also avoid bright lights and loud sounds. These can overstimulate the brain.
