Which statement about seizure prophylaxis in severe TBI is true?

• A. It reduces the risk of post-traumatic seizures.
• B. It cures intracranial hypertension.
• C. It prevents all infectious complications.
• D. It eliminates the need for imaging.

Answer: (A)

After a severe TBI, giving an anticonvulsant early aims to prevent seizures during the period when the brain is most vulnerable. Evidence shows that seizure prophylaxis lowers the risk of early post‑traumatic seizures, especially when started soon after injury and continued for a short period (commonly about a week). It does not cure intracranial hypertension, does not prevent all infectious complications, and it does not eliminate the need for imaging. It also does not reliably prevent late seizures long-term, but its proven benefit is reducing early seizures, which makes this statement true.
