Silent and Deadly{{/B}} Transient ischemic attacks (TIAs), or ministrokes, result from temporary interruptions of blood flow to the brain. Unlike full strokes, they present symptoms lasting anywhere from a few seconds to 24 hours. Rarely do they cause permanent neurological damage, but they are often precursors of a major stroke.
