What is a stroke, defined as the death or injury of brain tissue deprived of oxygen, formerly known as?

A stroke occurs when there is a disruption in the blood supply to the brain, resulting in the death or injury of brain tissue due to a lack of oxygen. This medical condition is medically referred to as a cerebrovascular accident (CVA). The term 'cerebrovascular' specifically pertains to the blood vessels in the brain, while 'accident' refers to the sudden onset of the event.

Cerebrovascular accident encapsulates both types of strokes: ischemic strokes, which are caused by a block in blood flow, and hemorrhagic strokes, which result from bleeding in the brain. By using the term CVA, healthcare professionals can quickly communicate the nature and urgency of the situation during assessment and treatment.

Other terms, such as those listed in the incorrect options, do not encapsulate the nature of a stroke as effectively as the term cerebrovascular accident does. For example, a carotid vessel aneurysm refers to a bulge in the carotid artery, which is not synonymous with a stroke, and while carotid vascular accident might suggest some kind of issue involving the carotid arteries, it is not the established terminology used in medical practice to describe a stroke.
