Cerebrovascular diseases mainly include cerebral thrombosis, cerebral embolism, cerebral hemorrhage and transient ischemic attack, which are also called “stroke” or “stroke”. Cerebrovascular disease is one of the most serious diseases that threaten human health. According to comprehensive domestic and international epidemiological data, the annual incidence of cerebrovascular disease is 0.1%-0.2%, the mortality rate is about 0.1%, and the disability rate is as high as 60%-80%. Autumn and winter are the high incidence of cerebrovascular disease, especially those who already suffer from hypertension, diabetes, atherosclerosis and other diseases increase the risk of sudden onset of cerebrovascular disease. According to statistics, more than 50% of stroke patients occur in the fall and winter seasons. Why is there a high incidence of cerebrovascular disease in autumn and winter? First, the temperature and airflow and other meteorological elements change drastically in autumn and winter, the temperature is low, the body is stimulated by cold, which leads to sympathetic excitation, the whole body capillary constriction, so that the heart and brain load increased blood pressure, the brain ischemia and hypoxia accelerated the formation of thrombus. Second, the dry climate in autumn and winter, the human body consumes more water, which easily causes dehydration in the body. After the lack of water, blood viscosity, blood flow slowed down, but also due to insufficient blood volume caused by ischemic stroke. Third, the elderly have poor adaptability to changes in the external environment, which can easily become a trigger factor for stroke. Therefore, the elderly must be vigilant in the changing climate of autumn and winter. How to effectively prevent and treat cerebrovascular disease? The first thing is to prevent the risk factors that cause the disease early, actively and effectively, so as to prevent the disease before it happens. 1.For hypertension, heart disease, diabetes, transient ischemic attack and arteriosclerosis, etc., once discovered, they should be given high attention and regular and long-term treatment and observation should be carried out under the guidance of doctors. 2.Take anti-platelet aggregation drugs, such as enteric aspirin, under the guidance of a doctor. Women of pregnancy age should avoid long-term use of contraceptives. 3.Change the bad lifestyle and adjust the diet structure. This includes quitting smoking, quitting drinking, combining work and rest, strengthening outdoor physical exercise, advocating low salt and low fat diet, etc. More fish, vegetables and fruits should be eaten. Recently, there are reports that moderate consumption of green tea and wine can prevent cardiovascular and cerebrovascular diseases. 4, pay attention to mental and psychological health, avoid violent mood swings, participate in more beneficial social activities, reduce tension, anxiety, depression. First, once slurred speech, numbness and weakness of one limb, sudden vision loss, blindness, sudden headache and vertigo occur, you should consult a doctor as early as possible for early diagnosis and early treatment. Secondly, some patients with cerebrovascular disease and high-risk groups of the disease are often given “preventive infusion” during seasonal changes, and this measure is not yet confirmed by strict clinical studies.
