Acquired brain injuries (ABIs) are not hereditary and do not occur before birth. There is a change in the brain’s neuronal activity, affecting all other systems in the body. At times, the injured person may appear to be perfectly fine, but delayed trauma can ensue. Swelling starts to happen, which blocks off the oxygen supply to the brain. From there, many other parts of the body are affected, such as your circulatory system and your other organs. If medical treatment is not provided right away, a brain injury could be fatal. Learn More
