The CDC estimates the annual burden of concussion in the United States to be roughly 1.4-3.8 million. Over the past decade, the CDC also reports a 70% increase in TBI emergency department visits, as well as an increase in TBI-related hospitalizations. Other studies have determined the prevalence of individuals with chronic concussion problems in the US is 5.3 million. Importantly, these figures should be considered an underestimate as patients with milder injuries often do not seek treatment.
