Which statement about age and prognosis after moderate-severe TBI is most accurate?

• A. Older age generally predicts better outcomes after moderate-severe TBI.
• B. Younger age generally has better recovery potential; older age and comorbidities predict poorer outcomes.
• C. Age has no impact on prognosis.
• D. Age only affects mortality, not functional recovery.

Answer: (B)

Age influences the brain’s ability to recover after injury. In moderate to severe TBI, younger patients generally have greater neuroplasticity and more functional reserve, which supports better recovery of skills and independence. As people get older, repair processes slow, and the likelihood of preexisting vascular and systemic comorbidities rises. These factors increase vulnerability to complications during rehabilitation and limit recovery potential, leading to poorer functional outcomes and higher mortality. While prognosis also depends on how severe the initial injury is and how well acute care is delivered, age and associated comorbidities consistently help explain why older patients tend to have worse outcomes.
