Since all personal injury cases, including TBI cases, involve medical injuries, it is essential that a lawyer has a good base of knowledge and understanding of medical terminology. This is essential when dealing with a traumatic brain injury since the attorney will be working with doctors and other medical personnel. In order to present the strongest case possible, the lawyer must be able to explain the medical condition in words that a jury can understand. If the lawyer is not intimately familiar with the medical aspects of the case himself, it will hinder their ability in explaining it to the jury.
