What is NOT a cause of a cerebrovascular accident?

• A. High blood pressure rupturing an artery
• B. Atherosclerosis occluding an artery
• C. An accidental injury to the cerebral artery
• D. A thrombus that clogs an artery

Answer: (C)

A cerebrovascular accident (CVA), commonly known as a stroke, typically occurs due to disruptions in the blood supply to the brain. The other listed causes relate directly to conditions that can lead to a CVA. High blood pressure can increase the risk of an artery rupturing, leading to hemorrhagic strokes; atherosclerosis involves the hardening and narrowing of arteries due to plaque buildup, which can restrict blood flow and result in ischemic strokes; and a thrombus is a blood clot that forms in a blood vessel, leading to blockage in the artery. An accidental injury to the cerebral artery, while potentially serious, does not represent a primary or common cause of cerebrovascular accidents. Typically, strokes arise from chronic health conditions and risk factors rather than from one-time external trauma to the arteries. Thus, choices relating to high blood pressure, atherosclerosis, and thrombus formation are recognized medical causes of CVA, solidifying that an accidental injury is not a typical cause.
