Age, gender, race and familial heritability are non-interventional risk factors. The risk of stroke continues to increase with age, with a higher incidence in men than in women. Hypertension, heart disease, diabetes, smoking, alcohol abuse, dyslipidemia, carotid artery stenosis, obesity, lack of physical activity, poor diet and nutrition, and drug abuse can be intervened. Several risk factors are: hypertension, hyperlipidemia, diabetes, atrial fibrillation, smoking, obesity or overweight, lack of physical activity, and a family history of stroke. Those with 3 or more are considered to be at high risk for stroke. Those with 2 or more are considered to be at intermediate risk. It should be taken seriously, otherwise it will result in hemiplegia for one person and a burden for the family, which will bring more human and economic burden to the family and the society.
