What are the two types of stroke, and which is more common?

• A. Ischemic stroke and hemorrhagic stroke; ischemic is more common
• B. Ischemic stroke only
• C. Hemorrhagic stroke only
• D. Transient Ischemic Attack and Ischemic stroke; both equally common

Answer: (A)

Strokes are categorized by what goes wrong with blood flow to the brain: a blockage stops blood and oxygen from reaching brain tissue, or a blood vessel ruptures and causes bleeding into the brain. The blocked form is ischemic, while the bleeding form is hemorrhagic. Ischemic strokes are far more common, making up about 80-85% of cases, while hemorrhagic strokes account for roughly 15%. A transient ischemic attack is not a stroke itself; it’s a temporary disruption of blood flow that resolves, so it isn’t counted as one of the two main stroke types. So the two main types are ischemic and hemorrhagic, with ischemic being the more common.
