Which statement about subdural hematoma is accurate?

• A. SDHs are usually detected early with mild symptoms.
• B. SDHs never cause neurological deficits.
• C. SDHs often are unrecognized until patients present with severe neurologic compromise.
• D. SDHs always present with rapid coma.

Answer: (C)

Subdural hematomas commonly bleed slowly from bridging veins, so the clinical course is often gradual rather than abrupt. This slow accumulation means early signs can be mild or nonspecific—headache, subtle confusion, or sleepiness—that don’t immediately point to a brain bleed. In older adults or people with brain atrophy, the space between the brain and skull is greater, allowing more blood to collect before neurologic symptoms become obvious. Because of this slower progression, a subdural hematoma is frequently not recognized until the patient develops significant neurologic decline or loss of consciousness. That’s why the statement describing it as often unrecognized until severe neurologic compromise is the most accurate. In contrast, many subdural hematomas do not present with rapid coma and can indeed show a range of deficits; they are not reliably detected early with only mild symptoms, and they can cause neurological deficits rather than being endlessly silent. Imaging, such as a CT scan, is key for accurate diagnosis when presentation raises concern.
