A transient ischaemic attack (TIA) or ‘mini stroke’ happens when the blood supply to the brain is interrupted for a short period of time. It is often called a ‘mini-stroke’, as the signs are the same as those of a stroke, but they do not last as long. The signs of a TIA may disappear in a few minutes and last no longer than 24 hours.
They are often a warning that a stroke may occur. The signs of a TIA depend on which part of the brain is not getting enough blood. They are the same as the signs of stroke and may include one or all of the following: Weakness, numbness or paralysis of the face, arm or leg on either or both sides of the body Difficulty speaking or understanding Dizziness, loss of balance or an unexplained fall Loss of vision, sudden blurred or decreased vision in one or both eyes Each year, approximately 120,052 strokes occur in the Singapore. NINDS is the leading supporter of research on stroke and TIA in the U.S. and sponsors studies ranging from clinical trials to investigations of basic biological mechanisms as well as studies with animals.
