A transient ischemic attack (TIA), also called a “mini stroke,” occurs when a blood clot blocks blood flow in the brain. The block is temporary (transient), and unlike an actual stroke, TIA doesn’t generally kill brain tissue. Knowing the signs of a TIA can help you get the treatment you need as early as possible.
Brief Time Window. Symptoms of a TIA can last as briefly as one minute, according to the American Stroke Association. Often, the symptoms are gone by the time a patient gets to the doctor.
