Stroke & Vascular Disorders
Subarachnoid hemorrhage (SAH), often occurring from rupture of an intracranial aneurysm, typically presents with a sudden severe headache and neck stiffness, and can be complicated by fatal rebleeding, arterial vasospasm producing ischemia, seizures, metabolic derangements, and venous thrombosis. The most common presenting complaint in SAH is the sudden onset of a painful headache followed by pain radiating into the occipital or cervical region. Meningismus develops as blood flows into the spinal subarachnoid space.
