What is a TIA?

  • A Transient Ischaemic Attack (TIA) is often referred to as a “mini stroke”. The symptoms are very similar to those of a stroke but the difference is that they resolve completely. A TIA can last for minutes to hours, but not longer than 24 hours. If the symptoms persist for longer than 24 hours then the event is called a stroke.
  • TIAs are caused by the blood supply to the brain being interrupted for a short period of time only.
  • TIAs are an important warning sign that all is not well with the blood supply to the brain. The risk of suffering a stroke within the first month after a TIA may be as high as 20 per cent, with the risk being highest in the first few days following a TIA.
  • If a person presents with the symptoms of a stroke (as listed on previous page) call 999
