Post-traumatic amnesia duration is a prognostic indicator for TBI outcomes.

• A. Post-traumatic amnesia duration is a prognostic indicator.
• B. Age.
• C. Initial blood pressure.
• D. Hair color.

Answer: (A)

Post-traumatic amnesia duration reflects how deeply the brain has been disrupted and how long it takes for memory and orientation to recover after a traumatic brain injury. The longer a patient remains in PTA, the more the injury has affected cognitive networks, which translates into a higher likelihood of persistent cognitive and functional deficits, longer hospital or rehab stays, and poorer overall outcomes. Because of this strong relationship with recovery trajectory, PTA duration serves as a prognostic indicator for TBI outcomes. Age and initial blood pressure can influence prognosis, but they are not the measure described in the statement and don’t directly map to the patient’s cognitive recovery timeline in the same way PTA duration does. Hair color has no relevance to brain injury prognosis.
