I believe that focal ischemia occurs when a specific portion of the
brain suffers from a diminished blood-oxygen supply, usually because
an artery is blocked or constricted. Global ischemia means that the
entire brain suffers, sometimes because of suffocation or heart
problems. That's all there is to it.
