Concussions are a serious brain injury that cause bruising and damage to the neurological tissue, more specifically the brain. This traumatic brain injury is most often seen in people who have been in a car accident, play contact sports, or anyone who may have taken a blow to the head. Bruising and swelling of the brain are physiological changes that occur during this traumatic injury.
Pressure on the brain tissue that is caused by the swelling may lead to initial symptoms of drowsiness, memory loss or blurred vision. Proper concussion testing should be administered to anyone who has taken a hit to the head. Neural tissue is damaged when the brain bounces against the inner surface of the skull.
