Statistics so far in 2015: cerebrovascular disease became the first cause of disability and death of our residents. In our country, one person has cerebrovascular disease every 12 seconds and one person dies from cerebrovascular disease every 21 seconds. Cerebral thrombosis: atherosclerosis and thrombosis of the arteries supplying blood to the brain, resulting in narrowing or even occlusion of the lumen, leading to the onset of local cerebral blood supply deficiency, which has a high incidence, disability and death rate, and is very easy to recur. Early symptoms of cerebral infarction: 1. sudden blackening of one or both eyes for a short time or blurred vision; 2. sudden double vision or vertigo; 3. sudden numbness or limb weakness of one side of the hand, foot or face; 4. sudden stupid tongue, unclear speech, crooked corner of the mouth, salivation; 5. sudden fall without any premonition, or short delirium. It is important to prevent the disease before it happens, not to mend it. Risk factors: 1, high blood pressure is the most closely related to the occurrence of cerebral thrombosis, the higher the blood pressure, the higher the risk of cerebral thrombosis; 2, diabetes is an independent risk factor for cerebral thrombosis, about 20% of diabetic patients eventually die of cerebral thrombosis; 3, dyslipidemia is significantly related to cerebral thrombosis, high blood pressure leads to blood vessel blockage induced cerebral thrombosis; 4, people with heart disease (coronary heart disease, arrhythmia, etc.), the risk of cerebral thrombosis is higher than normal people. The risk of cerebral thrombosis is 2 times higher than normal people; 5. Smoking is an important risk factor for cerebral thrombosis, and nicotine can raise blood pressure and accelerate vascular atherosclerosis; 6. Let’s keep health together and keep away from diseases.
