“Brain Injury” or “Traumatic Brain Injury” (TBI) means, a brain injury for purposes of this program, is defined as brain damage due to a blunt blow to the head; a penetrating head injury; crush injury resulting in compression to the brain; severe whiplash causing internal damage to the brain; or head injury secondary to an explosion.

Why are ABI (acquired brain injuries) specifically excluded? They are also brain injuries and are (cause) lifetime issues for those who have them. While my ABI was not Traumatic in the conventional sense, I can assure you, it is still a brain injury, that has traumatically altered my entire life, and left me with permanent deficits too.

Per the Brain Injury Association of America…..

“An acquired brain injury (ABI) is an injury to the brain that is not hereditary, congenital, degenerative, or induced by birth trauma. Essentially, this type of brain injury is one that has occurred after birth. The injury results in a change to the brain’s neuronal activity, which affects the physical integrity, metabolic activity, or functional ability of nerve cells in the brain. An acquired brain injury is the umbrella term for all brain injuries.

There are two types of acquired brain injury: traumatic and non-traumatic.”
