About Transient Ischemic Attack (TIA)
A transient ischemic attack, or TIA, is often referred to as a “mini-stroke.” However TIA is more accurately described as a “warning stroke” that should be taken seriously and treated as an emergency.

Most importantly, neither the person experiencing a TIA nor their loved ones can know whether this is a TIA or a full-blown stroke. Therefore, treat it as you would any stroke situation, by calling 911 immediately

TIA is caused by a blood clot in the brain. The only difference between TIA and stroke is that, with TIA, the blockage caused by the blood clot is transient, or temporary. Therefore, TIA symptoms occur rapidly and last a relatively short time, usually less than 15 minutes. 

The Danger: Up to 13% of people who experience TIA will have a stroke within 90 days, with the highest risk being immediately after the TIA episode. In addition, up to 30% of TIA patients could have a stroke within five years.*

About St. Luke’s TIA Center
St. Luke’s TIA Center is the only center of its kind in Idaho, dedicated to rapid evaluation and treatment to prevent stroke and further damage in patients experiencing TIA. Specialists with the TIA Center are onsite at St. Luke’s Boise and Meridian Emergency Departments 24 hours a day, 7 days a week, and provide:

  • Comprehensive diagnostic evaluation to help identify the underlying causes of the potential stroke. 
  • Once possible causes are identified, we provide appropriate treatment to prevent stroke, which may include specialty care and/or medications.
  • In order to most thoroughly and accurately determine the best course of care, patients remain in the TIA Center while we await the results of the evaluation.

TIA is an emergency situation, and should be taken very seriously to prevent a stroke that could lead to disability or even death. Call 911 immediately if you experience any signs or symptoms of stroke. The paramedics will arrive and take you quickly to the hospital. Do not drive your car.
