Concussion: Concussion is usually caused by trauma to the head causing the brain to be “shaken” inside the skull. Concussion is injury to the head area that may cause instant loss of awareness for a few minutes, or up to a few hours after the traumatic event. The most common disorder is a loss of consciousness.
Skull fracture: Skull fracture is a break in the skull bone. Skull fractures can be broken up into four main types: Linear skull fractures, depressed skull fractures, diastatic skull fractures and basilar skull fractures. If a fracture causes the bone to move, the displaced bone may press onto the tissue of the brain. This type of fracture often causes brain damage.
Intracranial hematoma: There are several type of blood clots in, or around the brain. The different types are classified by their location in the brain. These injuries can range from mild head injuries to quite serious and potentially life-threatening injuries.
There are many possible causes for head injuries. The most common causes include bicycles accidents, automobile accidents, falls, and work-related injuries. Contact sports, especially football, are another common source of head injury. Other sports that place a person at risk for head injuries include:
Almost any other contact sport
Head injuries are more common in an individual with:
An altered mental state as a result of drugs or disease.
Difficulty walking because of arthritis, leg injury, or neuromuscular disease.
Loss of balance or poor co-ordination from ageing or disease.
Head injuries can range from minor lacerations and bruises through to concussion, skull fractures, or bleeding within the skull or brain causing cerebral compression.
Penetrating trauma: Sharp instruments may break through the skull. The result of this is penetrating injuries. These type of injuries often require surgery. The initial injury itself may cause immediate death.
Blunt head trauma: Injuries like this may be from direct blow or from a rapid deceleration force.
Head injuries can be divided into three groups: Fully conscious at the time they are seen; those who have been unconscious since the time of the accident; and those who have been conscious for a period of time following the accident.
