Transient ischemic attack (TIA) facts

  • A transient ischemic attack (TIA) is a brief interruption of blood flow to part of the brain that causes temporary stroke like symptoms.
  • The risks for TIA are the same as for heart attack, stroke, and peripheral artery disease, and include smoking, high blood pressure, high cholesterol, diabetes, and family history.
  • The artery blockage may occur because of a ruptured plaque due to atherosclerosis or hardening of the arteries, debris that floats downstream from narrowed carotid arteries or blood clots (emboli) that form (often in the heart) and travel to block an artery in the brain.
  • Since TIAs resolve on their own, the goal for treatment is to minimize the risk of future TIAs and stroke. Treatment involves looking for the reason why the TIA occurred.
  • Treatment may include aspirin or other anti-platelet medications like Aggrenox or clopidogrel (Plavix).
  • It is important to educate the patient and family that should another stroke-like event occur, 911 must be called and emergency medical services activated, since there is no guarantee that symptoms will resolve.

Transient Ischemic Attack (TIA) Symptoms: A Trip to the ER

The event

A 73 year old woman is vacuuming when her left leg becomes weak and she has difficulty standing. Her face and left arm become numb. She calls for her husband, who helps her to a chair, and even though the symptoms resolve within five minutes, they decide to go to the hospital. In the hospital parking lot, they debate whether they should go into the Emergency Department or just turn around and go home.

This woman has suffered a TIA, or transient ischemic attack, which is basically a strokethat resolves on its own. Since the right side of the brain controls the left side of the body (and vice versa), she suffered reversible damage to her right brain and that caused her left leg to get weak and also developed numbness on the left side.

After some discussion, the woman decides she wants to seek medical care, and she and her husband walk through the Emergency Department doors. The doctor and nurse take a medical history to find out what happened. All of the symptoms have resolved, so the next step is follow-up care. The healthcare team asks the patient if she has any of the known risk factors for stroke (which are the same for heart disease):

  • high blood pressure,
  • high cholesterol,
  • smoking,
  • diabetes, and
  • family history.
