Apoplexy: A venerable term for a stroke, a cerebrovascular accident (CVA), often associated with loss of consciousness and paralysis of various parts of the body.

The word "apoplexy" comes from the Greek "apoplexia" meaning a seizure, in the sense of being struck down. In Greek "plexe" is "a stroke." The ancients believed that someone suffering a stroke (or any sudden incapacity) had been struck down by the gods.
