Do you know what a ministroke is? If you do, you're among the minority. A ministroke, or transient ischemic attack (TIA), is a brief episode of stroke symptoms caused by temporary interruption of blood flow to the brain. Most people suffer TIAs without realizing it.
But a third of the time, TIAs precede the full-blown, disabling strokes that are the nation's fourth leading cause of death. According to the Centers for Disease Control and Prevention and the National Stroke Association (NSA), each year, approximately 795,000 Americans have such strokes--and approximately 137,000 die.
In a stroke, fatty deposits or blood clots block a blood vessel (ischemic stroke) or, less common, weakened vessels burst (hemorrhagic stroke). Blood flow to that part of the brain ceases and brain cells die rapidly. Sometimes damage goes unnoticed, but other strokes leave victims unable to talk or use limbs.
