San Diego Brain Trauma Attorney Mark C. Blane briefly discusses how brain injury accidents occur when an external force causes injury to the axonal tissue of the brain. This type of injury is medically classified as a diffuse axonal injury or DAI. Brain injuries can be present without any external physical evidence, which makes them more difficult to prove in an injury case. The best way to legally prove brain injuries without any physical evidence or medical documentation is to bring in family members and those close to the victim, to testify to emotional changes within the victim. Often, emotional change is the best indication of a brain injury. If you think you or someone you love may have a brain injury, do not feel like you are alone.
