Traumatic Brain Injury
Every 21 seconds someone in the U.S. suffers traumatic brain injury. According to the National Center for Disease Control and Prevention, about 5.3 million people in the United States live with a disability that was caused by a traumatic brain injury (TBI). Motor vehicle crashes, falls, violent crimes and child abuse are major causes of sudden TBI and the leading cause of death and disability in children and young adults.

TBI can be categorized as mild, moderate, or severe:

• A mild case is called a concussion and the patient is usually awake following the injury. Approximately 80% of TBIs fall into this category.
  
• In a moderate case, the patient is sleepy following a brief loss of consciousness or disorientation. Approximately 10% of TBIs fall into this category.
  
• In severe cases, approximately 10% of TBIs, the patient is comatose, unable to respond.
