About Brain Injury

Brain injury is unpredictable in its consequences. Brain injury affects who we are and the way we think, act, and feel. It can change everything about us in a matter of seconds. 

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.

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

A non-traumatic brain injury is an alteration in brain function or pathology caused by an internal force.
