Causes
Causes of Head Injuries
There are many causes of head injury in children and adults. The most common injuries are from motor vehicle accidents (where the person is either riding in the car or is struck as a pedestrian), from violence, from falls, or as a result of shaking a child (as seen in cases of child abuse).
Causes of bruising and internal damage to the brain
When there is a direct blow to the head, the bruising of the brain and the damage to the internal tissue and blood vessels is due to a mechanism called coup-countercoup. A bruise directly related to trauma at the site of impact is called a coup lesion (pronounced COO). As the brain jolts backwards, it can hit the skull on the opposite side and cause a bruise called a countercoup lesion. The jarring of the brain against the sides of the skull can cause shearing (tearing) of the internal lining, tissues, and blood vessels leading to internal bleeding, bruising, or swelling of the brain.
Clinical Trials
Open trials refer to studies currently recruiting participants or that may recruit participants in the near future. Closed trials are not currently enrolling, but similar studies may open in the future.
