The brain is an important organ that is the hub of your personality, sensory perception, heartbeat and breathing regulation, muscular control, and many other things. Thus, when it is injured, you can lose control of all of these things and more. While it is obvious that your brain can suffer when a puncture wound breaks through the skull, it can also be damaged with closed head trauma.

Traumatic brain injury (TBI), also called intracranial injury, send an estimated one million people to the doctor's office each year. Of these, 50,000-100,000 will suffer long-term issues from the injury. These brain injuries can be caused by a variety of different factors, such as vehicular accidents, bike wrecks, pedestrian accidents, occupational accidents, falls, assaults, and many others.

The purpose of the skull is to give a hard, protective shield to the brain. However, when the head is strongly shaken, it can harm the brain without showing an external sign of damage. First, one risk of internal damage to the brain is the bleeding. As the brain is jostled about in the skull, it can tear the blood vessels that supply oxygen and nourishment to the organ.

More dangerous, as the blood continues to flow inside the skull, it can build up pressure inside the skull. Because the blood has nowhere to go, it begins to press on the brain. With prolonged pressure, parts of the brain can die off. This is the same with swelling of the brain.

A common injury, especially in children. A linear skull fracture is a simple break in the skull that follows a relatively straight line.A closed head injury is any injury to the head that does not penetrate the skull. Closed head injuries are usually caused by blows to the head and frequently occur in traffic accidents, falls and assaults.Brain contusions are bruises of the brain tissue that occur as a result of brain trauma.

Another problem is tearing become from closed head trauma of brain injury . Although it seems like the brain is closely packed within the skull, there is some space that allows it to slide from one side of the skull to the other. This is often called coup-countercoup injury because damage can occur to the side that initially hits as well as the side of the rebound.
