What is traumatic brain injury?
Traumatic brain injury (TBI) occurs when an external force traumatically injures the brain. An open TBI occurs when the skull is penetrated. Closed TBI involves internal injuries to the brain. The injury to brain tissue temporarily or permanently impairs brain function.
