For the typical personal injury attorney, medical knowledge is often a secondary concern. The primary issue for most personal injury attorneys will be establishing legal grounds for bringing a lawsuit against someone who causes injury or harm to other people. After all, that ability is why your client retained your services.
When an injury is visibly apparent, such as a broken bone or a spinal cord injury, it doesn't take much medical knowledge to convince the jury of the injury's severity and the financial impact it may have on your client. When the injury is invisible, as is the case with traumatic brain injuries (TBIs), it can be harder to sway a jury and make them understand the dire impact these injuries can have on a victim.
