What causes a hemorrhagic stroke?

• A. Blockage
• B. Atherosclerosis
• C. Embolism
• D. Burst blood vessel -> hemorrhage

Answer: (D)

Hemorrhagic stroke happens when a blood vessel in the brain ruptures, causing bleeding into brain tissue or into the surrounding spaces. This leakage damages brain cells and increases pressure inside the skull. Common causes include high blood pressure damaging vessel walls, ruptured aneurysms, or abnormal vessels such as arteriovenous malformations. The other mechanisms describe strokes due to loss of blood flow from a blocked artery (ischemic stroke), which is why they’re not the correct mechanism for a hemorrhagic stroke.
