What is a “mini-stroke” or TIA?
A “mini-stroke” refers to a transient ischemic attack (TIA). In a TIA, there is a short-term reduction in blood flow to the brain. This causes temporary stroke symptoms (often just for a few minutes) such as weakness or tingling in an arm or leg. TIAs don’t cause brain damage, but they are important warning signs that a person is at risk of having a stroke. 10 to 15 percent of strokes occur after a TIA. If you have a TIA, you should seek medical care right away to prevent a full stroke.
