Transient ischemic attack (TIA) is a temporary interruption of the blood flow to an area of the brain. A TIA is a warning sign that a stroke may soon follow.
A clot in an artery, a drop in blood pressure, or a change in heart rhythm or rate may all reduce blood flow to the brain and result in a TIA.
Symptoms of a TIA are similar to those of a stroke. They may include:
Unlike a stroke, a TIA does not cause lasting symptoms. Symptoms usually go away after 10 to 20 minutes.
