This bruises the surface of the brain, tears nerves and tears blood vessels. This is known as primary injury and how well a child does from a head injury depends on how much primary injury has occurred. Nothing can be done to reverse this damage which is why the most important aspect of head injuries in children is to stop them occurring in the first place. After primary injury is done certain secondary damage occurs as a result of the primary injury. These things can be prevented or sometimes reversed by good medical care and this is the main aim of hospital treatment.
People often worry about skull fractures.

While many children do recover completely from head injury, although it may take some time, permanent damage may occur. The damage may be primarily with learning ability and memory or it may be in moving a specific part of the body.
