A TIA or transient ischemic attack, also referred to as a "warning" or "mini" stroke, is an event with stroke-like symptoms lasting less than 24 hours. Although TIAs do not have long lasting effects or cause brain damage, they are a serious warning sign and should be treated as a medical emergency. Recognizing and treating TIAs can reduce your risk of a major stroke.


  • 40% of patients that have experienced a TIA, will go on to have an actual stroke
  • Among patients with TIAs, almost half experience a major stroke within the first two days
  • 10-15% will have a major stroke within 3 months of a TIA
