A Transient Ischemic Attack [TIA] is often called a mini-stroke, but it’s really a major warning. TIA is a temporary blockage of blood flow to the brain. Since it doesn’t cause permanent damage, it’s often ignored. But this is a big mistake. TIAs may signal a full-blown stroke ahead. When you first notice symptoms, get help immediately.
TIAs are very similar to ischemic strokes, which are also caused by blood clots. The main difference is that a TIA only lasts a few minutes. The clot then gets pushed along, like a temporary clog in a pipe, or chemicals in your body quickly break it down.
A transient ischemic attack (TIA) is like a stroke, producing similar symptoms, but usually lasting only a few minutes and causing no permanent damage. Often called a ministroke, a transient ischemic attack may be a warning.
Overview. A stroke is an interruption of blood flow to an area of the brain that lasts for long enough to cause permanent damage to the brain. If you want to know exactly how interruption of blood flow causes damage to the brain, you can find out more about that here. TIA stands for a transient ischemic attack.
TIA (transient ischemic attack, also sometimes called a “mini-stroke”) begins just like an ischemic stroke; the difference is that in a TIA, the blockage is temporary and blood flow returns on its own. Since blood flow is interrupted only for a short time, the symptoms of a TIA don’t last long – usually less than hour.
