Information for Patients

Transient Ischemic Attack

Also called: Mini-stroke, TIA

A transient ischemic attack (TIA) is a stroke that comes and goes quickly. It happens when the blood supply to part of the brain stops 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.
