When an accident occurs and there is an impact to an individual’s head, their brain tissue can be damaged, resulting in a brain injury. Primary injuries to the brain include cerebral contusions, lacerations and diffuse axonal injury, which can then be followed by secondary injuries such as cerebral oedema, hypotension, hypoxia and electrolyte imbalances. At the time of the injury - in addition to losing consciousness and experiencing various other symptoms of brain injury - the individual might also experience post-traumatic amnesia (PTA).
