How frequently does Traumatic Brain Injury, TBI, occur?
According to the Centers for Disease Control and Prevention, during 1990, there were roughly 2 million cases of traumatic brain injury. Of these, approximately 51,000 resulted in death. Data sources include vital registration data, hospital records, trauma registries, and personal interview surveys. Approximately three-quarters of TBI survivors are diagnosed as having suffered a mild to moderate injury — injuries that can be persistent and can affect many areas of learning and functioning.
