Stroke prediction is an ancient topic. More than 2,000 years ago, Chinese medical doctors of that time already put forward the idea of “treating the untreated” for prevention. The Qing Dynasty medical scientist Ye Tianshi (about A.D. 1666-1745) proposed the method of predicting stroke from the aura symptoms, and considered four symptoms such as numbness of the knuckles, paralysis within the p, numbness of the lips and tongue, and dizziness due to the moving pulse as the aura of stroke onset. The Qing dynasty medical doctor Wang Qingren (1768-1831 AD) summarized the aura symptoms of stroke systematically and concluded 34 aura symptoms before the onset of stroke. These medical doctors started the research on the prediction of stroke, and the conclusion of this research on the prediction of stroke from the aura symptoms still has the guiding significance in clinical medical treatment today. Today, the medical profession has done a lot of work on stroke prediction and has been able to make some inferences about stroke onset with the help of computers and laboratory tests, and to propose the risk of stroke onset with a certain degree of accuracy. In other words, the onset of stroke can be predicted, but its accuracy has yet to be further improved.
