Traumatic Brain Injury (TBI)

Traumatic Brain Injury (TBI) is an injury to the brain caused by an external force.

TBI can be caused by things like falls, assaults, motor vehicle accidents, sports injuries, and neurosurgery.

TBI is classified in several ways, including:
- Severity, ranging from mild traumatic brain injury (mTBI or concussion) to severe
- Mechanism (closed or penetrating head injury)

TBI is one of the two types of acquired brain injury, the other being Non-Traumatic Brain Injury (NTBI).
