Subdural hematomas are often unrecognized until what occurs?

• A. Severe neurologic compromise
• B. Immediate loss of consciousness
• C. Fever
• D. Nausea

Answer: (A)

Subdural hematomas often arise from tearing of bridging veins, so the bleeding into the space between brain and skull tends to be slow and progressive. Because the bleed grows gradually, initial symptoms can be subtle or nonspecific—headache, mild confusion, or slight weakness—easily overlooked after a head injury. As the collection enlarges, intracranial pressure rises and brain function deteriorates, leading to a sudden and severe neurologic decline or coma. That pattern—silent or mild initially with a later, abrupt worsening—is why these hematomas are often not recognized until severe neurologic compromise occurs. Fever and nausea aren’t characteristic early indicators of a subdural bleed, and immediate loss of consciousness is less typical for the common subdural presentation.
