Blood flow problem: Stroke is a problem with blood getting to brain tissue.  It can be from blood vessels being clogged ("ischemic"), or from blood leaking out because of high blood pressure, blood disorders, trauma, etc.  Either way, the tissue does not get enough oxygen and it gets injured.  Eventually it will die if blood flow is not restored fast enough.
