Why is a "stroke" called a "stroke"?

Best explanations I found on the world wide web, so I totally cannot take credit for this. Just thought it would be interesting to compile the etymology of some commonly used medical terms in various languages.

People tend to create an explanation for something they do not understand, and a stroke (medical term cerebrovascular accident) was not understood. Someone could appear to be in fine health, and could suddenly have a blood clot or plaque flowing through the blood come to rest in an artery in the brain, cutting off blood flow and causing sudden severe problems or death. The explanation, for centuries, was that someone had been struck down by God. The onset of autopsies to examine the body of someone who died showed the actual cause of the "stroke". The name stroke has remained.

在西医中，就是急性脑血管疾病，亦称脑血管意外、脑卒中，包括脑栓塞和脑出血，因这类疾病起病急骤，来势凶猛，病情变化迅速，像自然界的风一样“善行数变”、“变化莫测”，古代医家类比而名为“中风”。
