Transient ischemic attacks, or TIAs, are different from the other types of stroke because the flow of blood to the brain is only briefly interrupted. Even though they are referred to as “mini” strokes, TIAs should be regarded as medical emergencies just like the other kinds of stroke, even if the blockage of the artery is temporary. They serve as warning signs for future strokes and indicate that there is a partially blocked artery or clot source in the heart.

According to the Centers for Disease Control and Prevention (CDC), over a third of people who experience a TIA go on to have a major stroke within a year if they have not received any treatment. Between 10-15% will have a major stroke within 3 months of a TIA.¹
