What is (are) Transient Ischemic Attack ?
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.     NIH: National Institute of Neurological Disorders and Stroke
