A stroke that results from a clot forming at the site of occlusion is called which type?

• A. Thrombotic stroke
• B. Embolic stroke
• C. Ischemic stroke
• D. Stroke

Answer: (A)

This is about how a stroke is caused by a clot forming in place within a brain artery. When the clot develops right at the site of a narrowing or damage in a cerebral vessel and blocks flow there, the result is a thrombotic stroke. This in-situ clot formation is often tied to atherosclerosis, where plaque buildup makes the vessel prone to clotting at that spot and cutting off blood to the surrounding brain tissue.

In contrast, an embolic stroke happens when a clot forms somewhere else (like the heart) and travels through the bloodstream to lodge in a brain vessel. Ischemic stroke is the broad category for any stroke caused by reduced blood flow to the brain, which includes both thrombotic and embolic types. Stroke is the general term for any sudden brain dysfunction from vascular causes and includes hemorrhagic events as well.

So the type described—clot forming at the site of occlusion—fits thrombotic stroke.
