Brain injury is a condition in which the brain is altered and there is an impairment in cognitive and/or physical functioning, as well as possible disturbances in behavioral and/or emotional functioning. Traumatic brain injuries (TBI) are those that result from external forces, such as in a car crash. Acquired brain injuries include all injuries to the brain (including TBI) that occur after birth, but are not part of a hereditary, congenital, or degenerative condition such as Alzheimer’s Disease. The most common Non-TBI brain injuries include those that result from stroke and lack of oxygen (i.e., anoxia).
