Traumatic brain injury (TBI) is a significant social problem:

• 1.4 million people in the United States sustain a TBI each year
• 5.3 million Americans have long-term disabilities as a result of TBI, including post-traumatic epilepsy
• Sporting and recreational activities contribute to about 21% of all TBI among children and adolescents
• The annual cost to society is estimated at $60 billion, which does not include those injured in combat
• Those with TBI typically suffer both short- and long-term consequences, leading to acute or chronic neurological problems
• TBI is associated with a broad range of physical, cognitive, emotional, and social problems in individuals
