Transient Ischemic Attack
Known as a "mini-stroke," a transient ischemic attack, or TIA, occurs when there is a short-term blockage of blood flow in the brain, causing temporary damage to the brain cells. TIAs are often caused by blood clots.
While not as destructive as full-blown strokes, your doctor should know about them so as to pinpoint the cause, and help you take steps to prevent getting a stroke. If you have experienced a TIA, you are at increased risk of stroke.
