During which time frame does an acute subdural hematoma present after impact?

• A. Within 48 hours
• B. Within 1 week
• C. Immediately
• D. After 1 month

Answer: (A)

The main idea is the timing of when symptoms from an acute subdural hematoma appear after head trauma. Acute subdural hematoma usually shows up in the early period after injury, as bleeding from torn bridging veins accumulates and raises intracranial pressure. Among common clinical benchmarks, the acute phase is defined as occurring within roughly 24 to 72 hours after impact, and many exam resources use within 48 hours as the window for an “acute” presentation. So, the best choice is the timeframe that stays within that early period. Immediate onset is unlikely because symptoms generally don’t appear the instant the injury occurs; a week would place it in the subacute phase, and a month later would be chronic.
