Question

Quizplus · Accepted Answer

Transient ischemic attacks (TIAs) often warn of potential cerebrovascular accidents (CVAs) or strokes. A TIA is a temporary blockage of blood flow to the brain, which can cause symptoms similar to a stroke. However, unlike a stroke, TIAs do not usually cause permanent brain damage or necrosis. While hypertension can contribute to the risk of both TIAs and strokes, it is not a necessary factor. A TIA can be caused by a variety of factors, including blood clots, narrowed arteries, and heart disease. Rupture of an aneurysm or damaged artery is not typical of TIAs, as TIAs involve temporary rather than permanent blockages of blood flow.
