Traumatic Brain Injury or TBI is probably the most severe injury that can be sustained and not surprisingly the most costly injury a person can endure. For those reasons, insurance companies want to settle these claims as soon as possible to minimize their liability and financial exposure. A quick settlement of these cases is not in your best interest since you may not even know the full extent of your injuries so early in the process. The long-term prognosis of a traumatic brain injury may not be known for many months (maybe years) following the incident, so the proper diagnosis is of the utmost importance in these instances.
