What exactly is a transient ischemic attack (TIA)?

Houston Texans Coach Gary Kubiak collapsed on the sidelines of his team's game on Sunday after experiencing an apparent transient ischemic attack. So-called TIAs are sometimes referred to as mini-strokes. That term can seem to minimalize the condition, but TIAs can actually be signs of more serious problems to come: 30 percent of people who experience a TIA will go on to have a stroke if left untreated. In this video, Kathy Morrison, MSN, RN, CNRN, Stroke Program Manager at Penn State Hershey Neuroscience Institute, explains the basics about TIAs -- and why it is important to call 911 if you think you have experienced one.
