Transient ischemic attack (TIA, Mini-Stroke): A neurological event with the signs and symptoms of a stroke, but which go away within a short period of time. Also called a mini-stroke, a TIA is due to a temporary lack of adequate blood and oxygen (ischemia) to the brain.This is often caused by the narrowing (or, less often, ulceration) of the carotid arteries (the major arteries in the neck that supply blood to the brain).lso called a mini-stroke, a TIA is due to a temporary lack of adequate blood and oxygen (ischemia) to the brain.

It is important to know that: 1  A TIA is a warning sign of a future stroke. 2  A TIA is a medical emergency, just like a major stroke. 3  Strokes and TIAs require emergency care. 4  There is no way to know in the beginning whether symptoms are from a TIA or from a major type of stroke. 5  Like ischemic strokes, blood clots often cause TIAs.
