The causes of TBI are varied and appear to differ by age and gender (Coronado, Thomas, Sattin, & Johnson, 2005). The Centers for Disease Control and Prevention (Faul et al., 2010) identified the leading causes of TBI to be
- motor vehicle and pedestrian-related accidents,
- collision-related (being struck by or against) events,
- violent assaults.
Sports-related injuries and explosive blasts/military combat injuries are other leading causes of TBI. Acquiring a brain injury may predispose an individual to additional brain injuries before the symptoms of the first one have resolved completely. The second impact is more likely to cause brain swelling and widespread damage (Dessy, Rasouli, & Choudhri, 2014). See common classifications of TBI.
