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. 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 or trauma. Traumatic impact injuries can be defined as closed (or non-penetrating) or open (penetrating).

Brain injuries are complex and this information only scratches the surface. The BIAA website has lots of information on the various types of brain injuries, their effects, and more. Start your brain injury education journey here.
