What is the difference between acquired and traumatic brain injury?

An acquired brain injury is the umbrella term for all brain injuries. There are two types of acquired brain injury: traumatic and non-traumatic. A traumatic brain injury (TBI) is defined as an alteration in brain function, or other evidence of brain pathology, caused by an external force.

What is considered a traumatic brain injury?

Traumatic brain injury (TBI) is a sudden injury that causes damage to the brain. It may happen when there is a blow, bump, or jolt to the head. This is a closed head injury. A TBI can also happen when an object penetrates the skull.

What type of brain injury is an aneurysm?

A brain aneurysm can leak or rupture, causing bleeding into the brain (hemorrhagic stroke). Most often a ruptured brain aneurysm occurs in the space between the brain and the thin tissues covering the brain. This type of hemorrhagic stroke is called a subarachnoid hemorrhage.

Is a ruptured brain aneurysm a traumatic brain injury?

Intracranial aneurysms are classified as congenital, atherosclerotic, infectious and post-traumatic. The traumatic formation of the aneurysms can occur as a consequence of penetrating and non penetrating injuries1–3 and overall are considered to be responsible for less than 1% of all aneurysms.
