First Aid Tips #12: Head Injury
The hard skull and facial bones protect the brain, which is a soft organ. If the skull is injured, then the brain becomes more vulnerable. When someone has a knock to the head, the brain moves about and can knock against the skull and facial bones. This type of injury may cause the brain to swell and even bleed. The most common type of head injury is concussion. Concussion may or may not include loss of consciousness (blackout). The loss of consciousness is often brief and is normally followed by a rapid and complete recovery. Always seek medical attention for a head injury.
