A blood clot, either in the arterial or venous system.
A type of seizure that features rhythmic back-and-forth motion of an extremity and body stiffness.
A disorder of the brain in which brain cells temporarily stop working because of insufficient oxygen, causing strokelike symptoms that resolve completely within 24 hours of onset.
