What Is a TIA?

 

A TIA (Transient Ischemic Attack) is an early warning that a stroke (also called a brain attack) is coming. A TIA is a temporary stroke. The symptoms last from a minute to as long as 24 hours. It causes no lasting damage. But the effects of a stroke, if it happens, can be very serious and lasting. If you think you are having symptoms of a TIA or stroke — even if they don’t last — get medical help right away.
