Which stroke type results from rupture of a weakened blood vessel?

• A. Ischaemic stroke
• B. Transient ischemic attack
• C. Subarachnoid hemorrhage
• D. Haemorrhagic stroke

Answer: (D)

Rupture of a weakened vessel leads to bleeding within or around the brain, and that bleeding is the defining feature of a haemorrhagic stroke. The blood vessel breaks open, causing pressure and damage from the leaked blood rather than a primary blockage of flow. In contrast, an ischaemic stroke happens when a clot blocks a vessel and blood flow is reduced or cut off. A transient ischemic attack is a temporary disruption of blood flow with symptoms that resolve, leaving no lasting bleed. Subarachnoid hemorrhage is a specific type of haemorrhagic stroke where bleeding occurs in the space around the brain; the overall category that describes rupture of a vessel is haemorrhagic stroke.
