Any violent blow to the head that causes a brief unconsciousness that last only a few seconds can cause a concussion. This condition may be caused by sports injuries, falls, automobile accidents, industrial accidents, blows received in fights or any minor head injury. With a concussion the loss of consciousness is caused by a disturbance of the electrical activities in the brain. In most cases of concussion there is no association of damage to the brain but even so it should be treated as a serious occurrence and reported to a doctor. Although concussions cause a malfunction of the brain they do not result in any visible damage to the structure of the skull. In fact, concussions have been known to occur after even minor damage to the head if the brain has been jarred within the head.
