What is traumatic brain injury (TBI)?
Traumatic brain injury (TBI) is a form of brain injury caused by sudden damage to the brain. Depending on the source of the trauma, TBIs can be either open or closed head injuries.
- Open Head Injuries: Also called penetrating Injuries, these injuries occur when an object (e.g., a bullet) enters the brain and causes damage to specific brain parts. Symptoms vary depending on the part of the brain that is damaged.
- Closed Head Injuries: These injuries result from a blow to the head (e.g., when the head strikes the windshield or dashboard in a car accident).
Irrespective of the cause of the trauma, TBIs result in two types of damage to the brain: primary brain damage, which is damage that occurs at the time of impact (e.g., skull fracture, bleeding, blood clots), and secondary brain damage, which is damage that evolves over time after the trauma (e.g., increased blood pressure within the skull, seizures, brain swelling).
