Stroke is a disease caused by cerebrovascular diseases, mainly including cerebral infarction and cerebral hemorrhage. The high incidence of stroke may be related to the following factors:

1. Hypertension: Hypertension is the most common risk factor for stroke, because hypertension can damage the cerebral blood vessels, lead to cerebral arteriosclerosis and increase the incidence of stroke.

2. Unhealthy lifestyle: such as sedentary, unhealthy diet, excessive drinking and smoking will increase the risk of stroke.

3. Diabetes: Diabetes can damage blood vessels and nervous system and increase the risk of stroke.

4. Hyperlipidemia: Abnormal blood lipids will lead to increased blood viscosity and increase the incidence of stroke.

5. Age: With the increase of age, the circulatory system of the human body will gradually age, which will also increase the risk of stroke.

In a word, stroke is a disease that can reduce its incidence by actively preventing and managing risk factors. Maintaining a healthy lifestyle and controlling the risk factors of hypertension, diabetes and hyperlipidemia are important methods to prevent stroke.
