A blockage in arteries supplying blood that results in damage to the brain is called

• A. Stroke
• B. Cerebral Thrombosis
• C. Aneurysm
• D. Cerebral Embolism

Answer: (B)

Blockage of the brain’s blood vessels interrupts oxygen delivery and causes brain injury, which is a stroke. When that blockage is due to a clot that forms directly within the brain’s arteries, the specific term is cerebral thrombosis. This naming emphasizes that the clot originated in the brain's vessels and cut off blood flow there.

Other mechanisms exist: an embolism is when a clot travels from somewhere else and lodges in a brain artery, and an aneurysm is a bulging of a vessel that can rupture. While these can lead to stroke, cerebral thrombosis specifically describes a clot forming in the brain’s own arteries, making it the best match for the stem.
