A transient ischemic attack (TIA) is sometimes called a mini-stroke. As with a stroke, it occurs when the blood supply to the brain is interrupted but, with a TIA, this interruption is temporary. A TIA can be as short as a few seconds or last up to twenty-four hours. Unlike strokes, TIAs do not have lasting effects.

A TIA is often seen as a warning sign of a stroke and must not be ignored. People who have had a TIA are much more likely to suffer a stroke than those who have not.

TIA FACTS*
