Patient information Page Transient Ischemic Attack (TIA) Your GP or health professional suspects that you may have experienced a TIA, you may be referred urgently to a consultant who specializes in strokes for further testing or to a specialist or TIA clinic where you will be seen within seven days of your TIA occurring. What is a TIA? A transient ischemic attack (TIA), or 'mini-stroke', is caused by a temporary fall in the blood supply to part of the brain, leading to a lack of oxygen to the brain. This can cause symptoms that are similar to a stroke, although they do not last as long. A TIA lasts only a few minutes and symptoms are usually resolved within 24 hours. The main signs and symptoms of a TIA can be remembered by the word FAST: Face-ArmsSpeech-Time: Face. The face may have fallen on one side, the person may not be able to smile, or their mouth or eye may have drooped. Arms. The person with suspected stroke may not be able to raise both arms and keep them there, due to arm weakness or numbness. Speech. There may be slurred speech. Time. It is time to dial 999 immediately if you see any of these signs or symptoms. If signs and symptoms last longer than 24 hours, it is regarded as a full stroke. How common are TIAs? It's difficult to know exactly how common TIAs are, as many people who have TIA symptoms do not seek medical help. Approximately one person per 1,000 in the population is thought to suffer a TIA each year. This means more than 50,000 TIAs occur in England per year. TIA is a medical emergency If you have the symptoms of a further TIA, seek medical attention urgently. TIAs are a warning sign that further TIAs, or a full stroke, may occur soon. Without treatment, there is a one in 10 chance that you will have a full stroke within four weeks of having a TIA. A stroke is a serious condition and can cause permanent disability. As TIAs are serious, it is important that they are always investigated so that appropriate treatment can be given quickly. With treatment, the risk of a further TIA or a full stroke can be greatly reduced.
