Head injuries are typically caused by trauma to the head and in many cases can be directly related to brain injury. Along with a possible injury to the brain, most head injury cases entail an injury to the skull or the scalp. Although most head injuries are very minor it is important to understand the symptoms related with a severe head injury in order to take the appropriate precautions with this type of injury. If you believe that you or someone else has suffered from a head injury you should ensure that you stabilize the head and neck due to the potential of spinal cord or brain injury. In many cases it can be difficult to fully understand the extent of the injury so it is very important to seek medical attention when a head injury is suspected.
