About Transient Ischemic Attack
A transient ischemic attack (TIA) is a stroke that comes and goes quickly. It happens when a blood clot blocks a blood vessel in your brain. This causes the blood supply to the brain to stop briefly. Symptoms of a TIA are like other stroke symptoms, but do not last as long. They happen suddenly, and include
- Numbness or weakness, especially on one side of the body
- Confusion or trouble speaking or understanding speech
- Trouble seeing in one or both eyes
- Loss of balance or coordination
Most symptoms of a TIA disappear within an hour, although they may last for up to 24 hours. Because you cannot tell if these symptoms are from a TIA or a stroke, you should get to the hospital quickly.
TIAs are often a warning sign for future strokes. Taking medicine, such as blood thinners, may reduce your risk of a stroke. Your doctor might also recommend surgery.
