Transient Ischemic Attack (TIA)
Transient ischemic attack occurs in approximately 300,000 patients per year in the United States. Often referred to as a mini-stroke, a TIA is the result of a temporary interruption of blood flow to the brain.

Unlike a full-blown stroke, a TIA does not kill brain cells or result in permanent brain damage, but it can be an indicator of future stroke. Research indicates that 11 percent of patients diagnosed with TIA in an emergency room will experience a stroke within 90 days.
