TIA stands for transient ischemic attack. People who develop a TIA may experience symptoms over a short period of time due to a brief interruption of blood flow to the brain.
Some people may call TIAs “mini strokes,” but there’s an important difference between TIAs and strokes. A stroke is an actual injury to the brain that develops after the brain does not get the required amount of blood flow over a long period of time. In comparison, a person who has a TIA experiences symptoms briefly, but no injury occurs to the brain because the blood flow is restored before the injury develops.
