Transient Ischemic Attack Also called: Mini-stroke, TIA Summary A transient ischemic attack (TIA) is a stroke that comes and goes quickly. It happens when the blood supply to part of the brain stops briefly. Symptoms of a TIA are like other stroke symptoms, but do not last as long. They happen suddenly, and include Numbness or weakness, especially on one side of the body Confusion or trouble speaking or understanding speech Trouble seeing in one or both eyes Loss of balance or coordination Most symptoms of a TIA disappear within an hour, although they may last for up to 24 hours. Because you cannot tell if these symptoms are from a TIA or a stroke, you should get to the hospital quickly. TIAs are often a warning sign for future strokes. Taking medicine, such as blood thinners, may reduce your risk of a stroke. Your doctor might also recommend surgery.
