What term is used to describe a stroke or interruption of blood supply to the brain?

The term "Cerebrovascular accident" is used to describe a stroke or interruption of blood supply to the brain. This term encompasses both ischemic strokes, which occur when blood flow is blocked, and hemorrhagic strokes, which occur when a blood vessel in the brain ruptures. The phrase emphasizes the urgent medical condition that results from impaired cerebral circulation, leading to potential brain damage and loss of function based on the area of the brain affected.

The other terms provided refer to different concepts within the field of neurology and vascular health. "Cerebrovascular occlusion" specifically refers to the blockage of blood vessels in the brain but does not capture the broader implications of the acute event itself as a "Cerebrovascular accident" does. "Cineangiography" is a diagnostic imaging technique used to visualize blood vessels and blood flow, which is not related to the actual event of a stroke. "Collateral circulation" describes an alternate network of blood vessels that can supply blood to an area of the brain when the primary vessels are obstructed, but it does not define the stroke or the interruption itself. Thus, "Cerebrovascular accident" is the most accurate and encompassing term for the event in question.
