apoplexy

n. loss of movement, feeling, etc.; stroke, heart failure

Apoplexy is an old-fashioned medical term, which can be used to mean 'neurological impairment' or 'hemorrhage'. It can be used non-medically to mean a state of extreme rage. The word derives from the Greek word for 'seizure', apoplexia , in the sense of being struck down.
