Cerebrovascular disease is a general term for brain disorders caused by disorders of blood supply to the brain, with acute cerebrovascular disease being the most common. The pathological changes are sudden rupture or sudden occlusion of a cerebral blood vessel, which causes dysfunction of the brain tissue in the area innervated by that vessel. If cerebrovascular disease occurs, most of the lighter cases will suffer from dizziness and unfavorable movement of the affected limb, while the more severe cases may suffer from hemiplegia and aphasia, thus affecting the quality of life. Prevention of cerebrovascular disease requires attention to the following aspects: 1, the preparation of symptomatic drugs: for example, due to atherosclerosis caused by cerebral infarction, cerebral thrombosis can take some of the drugs with the role of the blood stasis, dissolving thrombus. 2, quit smoking: smoking is a risk factor for stroke, tobacco contains nicotine can make the right vascular spasm, blood pressure and accelerate atherosclerosis. Advocate to quit smoking. 3, quit alcohol: alcohol can increase blood pressure and put the blood in a hypercoagulable state. Long-term heavy drinking and acute alcoholism are risk factors for cerebral infarction. 4, weight control: It is currently believed that male abdominal obesity and high body mass index is an independent risk factor for cerebrovascular disease, which is related to the obesity prone to hypertension, hyperlipidemia and diabetes. 5, prevention and control of hypertension: hypertension is the most important risk factor for cerebral hemorrhage and cerebral infarction, control of hypertension is the core of stroke prevention and development. For the prevention and treatment of hypertension should reduce alcohol consumption, maintain an optimistic attitude and improve stress capacity and long-term adherence to antihypertensive drugs. According to the standards of the World Health Organization, the blood pressure of healthy people should be controlled under 140/90mmhg. 6, prevention and control of heart disease: various types of heart disease can increase the risk of cerebrovascular disease, including atrial fibrillation is the most important. Heart disease often causes embolic stroke, preventive measures are mainly the application of anticoagulants and antiplatelet drugs. The incidence of atherosclerosis and obesity in diabetic patients is higher than that in non-diabetic patients, and hyperglycemia is an independent risk factor for the development of hyperglycemic stroke. 8. Prevention and treatment of dyslipidemia: LDL is a risk factor for carotid atherosclerosis, but hypercholesterolemia is not a risk factor for stroke. Prevention and treatment emphasizes diet control and physical exercise, supplemented by drug therapy, such as statins. For secondary dyslipidemia caused by diabetes mellitus, etc., the primary disease should be actively treated.
