Transient Ischemic Attack (TIA)

A TIA occurs when there is a temporary blockage in an artery leading to, or inside the brain. The lack of blood flow that results from a temporary blockage will produce the symptoms of a stroke. These symptoms occur rapidly and will only last for a short period of time before they disappear. Unlike a stroke, the blockage in a TIA is temporary, and when a TIA is over, there is no permanent injury to the brain. However, there is no way to know if stroke symptoms will lead to a TIA or a major stroke, so it’s important to call 911 immediately if you or someone else experiences symptoms of a stroke.
