Roughly 450,000 people in the United States will suffer from head injuries this year. The numbers are growing as people spend more time in extreme sports, ride vehicles without proper protection, particularly head gear, and as our service men and women fill military assignments in hostile environments. The majority of individuals who have moderate to severe injuries will have vertigo and balance problems for up to 5 years; many will not be able to be employed. Traumatic brain injury can result in multiple symptoms such as auditory processing disorders, balance problems, hearing loss and tinnitus.  Audiologists are in the forefront in evaluating patients with these hearing and balance disorders.
