Which symptom is classically associated with subarachnoid hemorrhage?

• A. Neck stiffness
• B. Thunderclap headache
• C. Visual disturbance
• D. Gradual headache

Answer: (D)

Subarachnoid hemorrhage is classically marked by a thunderclap headache: a sudden, incredibly severe headache that reaches its maximum intensity within seconds. This abrupt onset reflects abrupt blood irritation of the meninges at the time of aneurysmal rupture. Neck stiffness can occur due to meningeal irritation, but the defining, most characteristic feature is the sudden, peak-in-an-instant headache. Visual disturbances and gradual headaches are less typical for SAH; a gradual headache suggests other conditions like tension or migraine.
