Which symptoms characterize subarachnoid hemorrhage?

• A. Rapid progression, sudden onset headache, vomiting, confusion, altered consciousness, seizures
• B. Gradual onset mild headache
• C. Only dizziness with no loss of consciousness
• D. Nocal headache with focal weakness

Answer: (A)

Subarachnoid hemorrhage is a life‑threatening bleed into the space around the brain that irritates the meninges. The defining pattern is a sudden, severe headache often described as a thunderclap, reaching maximal intensity within seconds to minutes. This abrupt pain is typically accompanied by rapid deterioration in mental status and can include vomiting, confusion or altered consciousness, and sometimes seizures as the irritated brain tissue responds to the bleed. The urgency and combination of a dramatic onset with signs of meningeal irritation and acute neurologic change make this presentation classic for SAH. Other patterns don’t fit SAH as well. A gradually worsening, mild headache is more typical of tension-type headaches or low‑pressure issues, not an abrupt hemorrhage. Dizziness with no loss of consciousness points toward vestibular or inner-ear problems, not the sudden, high‑pressure bleed into the subarachnoid space. No focal headache with focal weakness would be unusual for SAH, which often presents with a severe generalized headache and signs of meningeal irritation; focal deficits are less characteristic and don’t define SAH.
