Which stroke is caused by a blockage in a brain vessel?

• A. Ischemic stroke
• B. hemorrhagic stroke
• C. CVA (stroke)
• D. Alzheimer's Disease

Answer: (A)

Blockage in a brain vessel reduces blood flow to brain tissue, depriving neurons of oxygen and nutrients and causing damage—this is an ischemic stroke. It’s the most common type of stroke and happens when a clot forms in a brain artery or travels from somewhere else to block one. In contrast, a hemorrhagic stroke comes from a ruptured vessel with bleeding into the brain, not a blockage. The term cerebrovascular accident is an older, general label for stroke and doesn’t specify the cause. Alzheimer’s disease is a neurodegenerative condition and not a stroke caused by a blocked blood vessel.
