Any time your head hits a part of the vehicle there is potential for a head injury. Cuts and bruises are the most obvious injuries. However, the brain can be damaged by sudden head movement even if there are no outward signs of injury. An injury to the head brings a risk of brain swelling (which can block the flow of oxygen to the brain), nerve damage and other conditions that can lead to long-term problems.
Head injuries can cause victims to be confused or can be observed by a person’s difficulty in breathing or lack of energy. Symptoms might not be immediately apparent after a car wreck, but might appear hours or even days after the accident and can include headaches, dizziness, behavioural changes, memory loss and depression.
