Classic presentation of subarachnoid hemorrhage?

Subarachnoid hemorrhage most often presents with a sudden, severe headache that reaches its maximum intensity within seconds to minutes—described classically as thunderclap or the worst headache of life. This abrupt onset reflects blood irritating the meninges after a ruptured cerebral aneurysm, and it is the hallmark finding you should recognize in an acute setting. Additional signs can include neck stiffness, photophobia, nausea or vomiting, and, in some cases, altered consciousness, but the defining feature is the rapid, explosive onset of severe headache. The other options describe symptoms more typical of other conditions—chest pain suggests cardiac or aortic processes, gradual dizziness points away from an acute hemorrhage, and nausea/vomiting alone is nonspecific—whereas the sudden, thunderclap onset is the classic clue to SAH.
