”Stroke is also called “stroke” and “cerebrovascular accident”. It is an acute cerebrovascular disease, which is caused by the sudden rupture of a blood vessel in the brain or the blockage of a blood vessel that prevents blood from flowing to the brain, resulting in brain tissue damage, including ischemic and hemorrhagic strokes. The incidence of ischemic stroke is higher than that of hemorrhagic stroke, accounting for 60% to 70% of all strokes. Occlusion and stenosis of the internal carotid artery and vertebral artery can cause ischemic stroke, which is more common in men than in women over the age of 40 and can cause death in severe cases. The mortality rate of hemorrhagic stroke is high. Surveys show that stroke has become the first cause of death in China in both urban and rural areas combined, and the leading cause of disability in Chinese adults. Stroke is characterized by high incidence, high mortality and high disability rates. Different types of stroke are treated in different ways. Because of the persistent lack of effective treatment, prevention is currently considered the best measure, with hypertension being an important controllable risk factor for stroke, and therefore antihypertensive treatment is particularly important to prevent stroke onset and recurrence. Education on stroke risk factors and aura symptoms should be strengthened to prevent and treat strokes. How to prevent and treat stroke? 1. Keep blood pressure at a reasonable level. Many stroke attacks are related to emotional stress. 3. Obesity is a recognized risk factor for stroke. 4, scientific and reasonable diet with low fat, low calorie, low salt diet, with sufficient high-quality protein, vitamins, fiber and trace elements. 5. Climate change is closely related to human health. Especially in the cold and summer, the elderly have poor adaptive capacity and lower immunity, so the morbidity and mortality rate are higher than usual, so we should be especially careful. 6, timely treatment of diabetes, coronary heart disease, liver and kidney insufficiency and other diseases. 7.Moderate physical activity is good for health. 8, pay attention to the aura of stroke: one side of the face or upper or lower limbs suddenly feel numb, weakness, crooked mouth, drooling. Sudden difficulty in speaking or not understanding others’ words. Suddenly feel dizzy and wobbly. Short-lived confusion or drowsiness. Unbearable headache.
