Transient ischaemic attackSymptomsSevere symptoms of transient ischaemic attacks (TIAs) usually last less than 30 minutes and all symptoms disappear completely within 24 hours. If symptoms last more than 24 hours, then it is classed as a full stroke.
Symptoms may include:
weakness or numbness on one side of the body,vertigo (dizziness),feeling faint,confusion,slurring of speech,difficulties with swallowing,loss of the understanding of the meaning of words or the names of objects,memory problems, andtemporary loss of consciousness.Another common symptom of a TIA is amaurosis fugax. This is a temporary loss of vision, usually for a few seconds or minutes, caused by interference to the blood supply to parts of your brain or eye. It is painless and may occur several times during a TIA.
If you suspect that either you or someone else is having a stroke, you should seek medical attention immediately. Call 999 and ask for an ambulance.
Recognising a TIA in other people
The Stroke Association recommends using the face-arm-speech-test (FAST) to help you recognise the symptoms of a TIA and stroke in other people. This is a simple test that can help you find out if someone has had a TIA or stroke:
Face - can the person smile, or has their mouth or eye drooped?Arm - can the person raise both arms?Speech - can the person speak clearly and understand what you say?If the person has failed any of these tests, they may be having a full stroke. You should call 999 and ask for an ambulance.
If a person has failed any of the above tests, but severe symptoms clear up quickly, they have probably had a transient ischaemic attack (TIA). They will need to see their GP as soon as possible.
