What is Brain Injury?
Brain Injury (BI) is general term referring to any injury to the brain. Aquired Brain Injury (ABI) and Traumatic Brain Injury (TBI) make reference to the source of injury.
Traumatic brain injury (TBI) results from an external force to the brain causing temporary or permanent neurological dysfunction. It is a relatively high-prevalence injury, being 10 times more common than spinal cord injury. The incidence is highest in people in the prime of their lives, coinciding with important events such as completing their education, developing their careers and establishing their families, and thus at a time when they are more likely to have financial problems. Much of the disability (and costs) associated with TBI is hidden, as survivors may have no physical evidence of their injury. Despite this, the consequences of TBI can severely and permanently change a person's life, resulting in family disruption, loss of income and earning potential, and considerable expense over a lifetime.1
The range of severity of TBI is broad, from concussion through to persistent vegetative states.
