Types of traumatic brain injury include:

1: Diffuse axonal injury. Shaking or strong rotation of the head causes brain structures to tear. Nerve tissue is disturbed throughout the brain.

2: Concussion. Caused by a physical force to the head that causes blood vessels to stretch and cranial nerves to be damaged.

3: Contusion. A result of a direct impact to the head, which causes bleeding on the brain.

4: Coup-contrecoup injury. The force to the brain is large enough to cause contusion at the side of impact, as well as the site opposite impact.

5: Penetration injury. The impact causes a foreign object to penetrate the skull.
