The Basics
What’s the difference between a TIA and a stroke?
A stroke causes brain damage, and a TIA doesn’t.
TIA stands for transient ischemic (“is-KEM-ik”) attack. A TIA is when blood flow to the brain is blocked for a short period of time and there isn’t any damage to the brain. After you’ve had a TIA, you are at greater risk for a stroke.
The signs of a TIA are the same as the signs of a regular stroke, but they don’t last as long. Never ignore a TIA. Call 911 right away if you or someone with you has signs of stroke.
