What is a brain injury?
Brain injuries are classified as traumatic or non-traumatic. A traumatic brain injury (TBI) results from a blow to the head, such as from a fall, a car accident, a gunshot wound or an explosion. A non-traumatic brain injury (NTBI), which involves no external force, may result from a stroke, a tumor, an infection, or a lack of oxygen.
Since the brain is our center for speech, thinking, movement and emotion, brain injuries can affect our abilities in many different ways, depending on the severity of the injury.
