Transient Ischemic Attack
Alternate Terms:- Mini-Stroke
- TIA
Transient ischemic attack (TIA) is a temporary interruption of the blood flow to an area of the brain. TIAs are 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:
- Vision problems.
- Difficulty speaking, or unusual behavior and thought processes.
- Difficulty understanding words.
- Loss of consciousness.
- Seizures.
- Dizziness (vertigo) or trouble walking.
- Weakness or numbness on one side of the body.
Unlike a stroke, a TIA does not cause lasting symptoms. Symptoms usually go away after 10 to 20 minutes.
A TIA is considered a warning sign of an impending stroke.
