The Centers for Disease Control (CDC) defines a traumatic brain injury (TBI) as a disruption in the normal function of the brain that can be caused by a bump, blow, or jolt to the head, or penetrating head injury. According to the CDC, an estimated 2.8 million people sustain a traumatic brain injury annually. 52,000 die, 282,000 are hospitalized and 2.5 million are treated and released from an emergency department. Falls were the leading cause of TBI and accounted for 47% of all TBI-related ED visits, hospitalizations, and deaths in the United States.
