Hemorrhagic stroke accounts for 10-15% of all strokes and is associated with higher mortality than ischemic stroke. Patients often present with headache, altered mental status, seizures, nausea/vomiting, or hypertension. The bleeding occurs directly into the brain from damaged arteries, and mortality is high, with 40-80% dying within 30 days. Risk factors include age, hypertension, amyloidosis, coagulopathies, anticoagulation, cocaine abuse, and genetic conditions. Treatment focuses on stabilizing vital signs, controlling blood pressure and seizures, and reducing intracranial pressure if elevated.
