What is a transient ischaemic attack?
A transient ischaemic attack or TIA is very like a stroke except that it passes quickly; the symptoms of weakness of one side of the body, tingling and twisting of the mouth or loss of speech or disturbance of vision last only for a few minutes and then disappear. TIAs occur because, for a short time, not enough blood reaches part of the brain. They can be treated and anyone who experiences a TIA should see their doctor immediately.
