Epidural hematoma classically presents as a brief loss of consciousness after head injury, followed by a period where the person seems awake and normal (lucid interval), and then rapid deterioration as the hematoma expands and increases intracranial pressure. This pattern comes from arterial bleeding (often a torn middle meningeal artery) that bleeds quickly, so the brain is momentarily overwhelmed and then, as the hematoma grows, the patient’s level of consciousness drops abruptly with worsening neurological signs. In the field, you’d look for a temporal bone impact, a short coma initially, a lucid interval, and then a rapid decline with possible pupils changes or new focal deficits. Other options describe non-classic timelines (immediate coma, gradual days-long worsening, or vague anxiety) that don’t match the rapid expansion and lucid interval hallmark of epidural hematoma.
