What is the typical time course for symptoms of a subdural hematoma and which symptoms are common?

• A. Progress over hours to days with headache, confusion, vomiting
• B. Sudden thunderclap headache with neck stiffness
• C. Seizures without headache
• D. Chronic mild fatigue with no neurological signs

Answer: (A)

Subdural hematomas typically evolve gradually after injury because blood collects slowly between the dura and arachnoid, so symptoms tend to develop over hours to days rather than appearing immediately. The most common presentation is headache, often accompanied by confusion or altered mental status as the pressure on the brain increases, and sometimes vomiting from raised intracranial pressure. Focal neurologic signs can occur but aren’t required for the diagnosis. This pattern fits the given scenario of symptoms progressing over hours to days with headache and confusion (and sometimes vomiting), which is distinct from the sudden “thunderclap” onset seen with subarachnoid hemorrhage, the possibility of seizures without headache, or chronic fatigue without neurologic signs.
