How does age influence TBI prognosis?

• A. Prognosis depends only on initial injury severity.
• B. Age does not affect prognosis.
• C. Older age is associated with better outcomes.
• D. Younger patients have greater neuroplasticity and potential for recovery; older age is associated with worse outcomes.

Answer: (D)

Age influences recovery after traumatic brain injury, acting as a key modifier of prognosis. Younger patients tend to have greater neuroplasticity, meaning the brain’s networks can reorganize more effectively after injury and during rehabilitation. This higher plasticity supports better functional recovery and adaptation to deficits. In contrast, older individuals often face reduced neuroplasticity, more brain degeneration with age, more vascular and comorbid conditions, and less reserve to cope with injury, all of which can lead to worse outcomes. Because prognosis is shaped by multiple factors, age adds important nuance beyond the initial injury severity, making younger age associated with better outcomes and older age associated with worse outcomes. The other statements overlook the multifactorial nature of recovery and the well-documented influence of age on neurorecovery.
