Cerebrovascular disease is due to various causes of cerebrovascular circulation disorders, clinically seen in severe headache, dizziness, distorted eyes and mouth, speech disorders, hemiparesis, urinary and fecal incontinence, convulsions, coma and many other symptoms or signs, and in severe cases, brain herniation death occurs quickly. The onset of the disease is sudden. Also known as cerebrovascular accident. It is usually caused by long-term atherosclerosis, hypertension, wind heart disease, cardiogenic embolism, arteritis, hematologic disease, metabolic disease, drug reaction, tumor, connective tissue disease, etc. It can also be caused by trauma. The cause is not known in individual patients. These causes can lead to narrowing and occlusion of blood vessels in the brain, which can cause local ischemia or bleeding due to rupture of blood vessels, leading to cerebrovascular disease, which is known as cerebral infarction or cerebral hemorrhage. Epidemiological investigations have shown that a number of factors are closely related to the occurrence of stroke and are considered to be causative factors of the disease, also known as risk factors. They are divided into two categories: those that cannot be intervened such as age, genes and heredity; and those that can be intervened, and if these factors can be effectively intervened, the incidence and mortality of cerebrovascular disease can be significantly reduced. Risk factors for stroke include age, genetics, hypertension, hypotension, heart disease, arrhythmia, carotid artery stenosis, fundus arteriosclerosis, diabetes, hyperlipidemia, hyperhomocysteinemia, smoking, alcohol consumption, obesity, oral contraceptives, dietary factors such as high salt, meat, high animal oil diet, strong coffee and tea, and excessive heavy physical activity, all of which are risk factors for cerebrovascular disease. The occurrence of cerebrovascular disease can be significantly reduced by intervening interventional risk factors. Such as reasonable regulation of blood pressure. For hyperhomocysteinemia, fresh vegetables, fruits, lean meat and fish can be consumed to increase the intake of folic acid, vitamin B6 and B12 to reduce the risk factors.
