Transient Ischemic Attack

A transient ischemic attack (TIA), sometimes called a "mini-stroke" is a stroke that lasts only a few minutes. It occurs when the blood supply to part of the brain is briefly interrupted. TIA symptoms, which usually occur suddenly, are similar to those of stroke but do not last as long.
Because there is no way to tell whether symptoms are from a TIA or an acute stroke, you should assume that all stroke-like symptoms signal an emergency and should not wait to see if they go away.
A prompt evaluation (within 60 minutes) is necessary to identify the cause of the TIA and determine appropriate therapy. Depending on your medical history and the results of a medical examination, the doctor may recommend drug therapy or surgery to reduce the risk of stroke in people who have had a TIA.
A TIA increases the risk of a future stroke.
