Document Summary
Acquired vs. traumatic brain injury: acquired brain injury you didn"t have a brain injury, but now you have. It can be the result of a disease, poisoning, or other types of damaging conditions. This is the broader category: traumatic brain injury is an acquired disability, but it is the result of external force damaging the brain. Open head injuries: there is some sort of penetration to the skull. It may be something like a gunshot wound. There is bleeding (external), fracture to the skull. It is clearly identifiable, like other external injuries. Closed head injuries: we don"t see external damage to the brain. This skull stops, but because the brain is a soft organ and connected to brainstem, it will keep moving forward until it hits the skull internally. Resulting in internal bleeding pressure of the brain brain damage over time. The stem can be pulled forward (stretched), and this can cause damage.
