Brain injuries can be particularly devastating for families. If brain function is limited due to damage, then quality of life can fall drastically. There are two basic types of traumatic brain injury: closed and penetrating.
With penetrating injuries, a foreign object enters the brain. One example would be a bullet going through the skull and brain. Surgeons can examine the patient and conduct tests to determine which area suffered damage, and symptoms will vary based on the area that was damaged. With closed-head injuries, the brain is damaged as the result of a hard blow to the head. Examples include falling, hitting the head on a car dashboard or being struck with an object.
