Which of the following is a prognostic indicator for TBI outcomes?

• A. Favorite sport.
• B. Age.
• C. Hair color.
• D. Blood type.

Answer: (B)

Age is a prognostic indicator for TBI outcomes because a patient’s age reflects brain reserve and overall physiological resilience. Younger individuals generally show greater neuroplasticity, fewer comorbidities, and more reserve to cope with injury and recover function. As age increases, these protective factors diminish, and the likelihood of complications, slower recovery, and poorer functional outcomes rises. This relationship between age and recovery is consistently observed across injury severities, making age a reliable predictor of prognosis.

The other options don’t have a meaningful impact on TBI outcomes. Favorite sport has no direct effect on brain injury biology or recovery. Hair color is unrelated to neurological recovery. Blood type does not determine prognosis in standard clinical practice for TBI.
