Risk Factors for TBI

TBI occurs twice as often in men as in women. Populations at a higher risk include the following:

  • Individuals between the ages of 15 and 24 years
  • Individuals age 75 and older

Half of all traumatic brain injuries involve alcohol use, either by the victim or the person causing the injury.

Children age five and younger are also at a higher-than-average risk. According to the National Pediatric Trauma Registry, more than 30,000 children are permanently disabled each year as a result of brain injuries.

The greatest risk occurs from mid-afternoon to early evening, and during weekends and the summer months. Children are especially at risk after school. Nearly half (42.6 percent) of all children's injuries occur in roads, 34.3 percent occur at home, and 6.6 percent occur in recreation areas.
