Which factor is implicated in the greatest number of injuries associated with TBI?

• A. Alcohol use
• B. Weekends
• C. Evenings and nights
• D. Sports injuries

Answer: (A)

Alcohol use is the factor most implicated in injuries leading to traumatic brain injury. When someone has consumed alcohol, judgment, balance, coordination, and reaction time are all impaired, which raises the risk of many injury types—driving under the influence, falls, assaults, and other trauma—that can result in brain injury. This broad impact across a wide range of mechanisms means alcohol involvement appears in a larger number of TBI cases than any single context or mechanism. While weekends, evenings and nights, and sports injuries are associated with higher injury risk, they describe when or how injuries occur rather than a factor that broadly increases risk across diverse situations. Alcohol use spans many of these contexts and adds risk across the board, making it the most prevalent contributor to injuries that lead to TBI.
