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. It usually 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.

If you have any symptoms of a TIA or stroke, call 911 and your doctor as soon as possible.
