Cerebral infarction, also known as ischemic cerebrovascular disease, is a sudden decrease or cessation of blood flow in the arteries supplying brain tissue, thus causing ischemia and hypoxia in brain tissue, resulting in brain tissue necrosis, which manifests as sensory-motor impairment of limbs and loss of speech function. Head CT or MRI can help clarify the diagnosis of the disease. So, under what circumstances should such examinations be done, that is, what clues suggest ischemic cerebrovascular disease? I. 5 signs of cerebral infarction 1. blurred vision It is manifested as transient visual impairment or visual field defect, which mostly recovers on its own within one hour. 2.Lateral palsy That is, transient ischemic attack, strictly speaking, this is already the lightest stroke. 3.Yawning Continuous Yawning Most of the people who yawn frequently within 5 to 10 days before the onset of ischemic stroke can reach about 80%, which is an important alarm signal. 4.Stuttering The symptoms of salivation are poor speech and drooling, with signs of stroke, which may come on suddenly. 5. Transient black blindness Suddenly appearing black in front of the eyes, unable to see anything, and recovering in seconds or minutes, also accompanied by nausea, vomiting, dizziness and impaired consciousness. Second, understand the causes of cerebral infarction, and actively prevent 1. high blood pressure and diabetes The chances of cerebral infarction in patients with high blood pressure are 7 times higher than normal people. Therefore, attention should be paid to controlling blood pressure in the normal range to avoid cerebral infarction. Diabetic patients are also significantly more likely to suffer from cerebral infarction than those without diabetes. 2, irregular life irregular life, such as often staying up late, irregular or unreasonable diet, and excessive work pressure, etc., can also lead to cerebral infarction. Sometimes viral invasion of cerebral vessels may also cause cerebral infarction. 3, long-term smoking and drinking Some clinical studies show that more than 50% of patients with cerebral infarction will have a long-term history of smoking and drinking alcohol. Because smoking will cause the lipid and fibrinogen content in the blood to rise, increasing blood viscosity. Drinking alcohol will lead to an increase in the content of alcohol in the blood, resulting in cerebral vasoconstriction and spasm. 4, seasonal and emotional impact Cerebral infarction can develop year-round, but more in the seasonal changes in the formation of the peak incidence, such as: temperature, air pressure, humidity and other changes more drastic, so in the year formed two small peak, respectively, autumn and winter and spring transition; at the same time, mental depression, long-term depression, mental agitation, excessive tension is also easy to trigger the disease. How to prevent cerebral infarction: 1, pay attention to the aura signs such as dizziness, headache, numbness of limbs, drowsiness and drowsiness, personality abnormalities, you should take treatment measures to avoid the occurrence of cerebral infarction. 2.Eliminate triggering factors Mood swings, excessive fatigue, excessive force, etc. should be self-controlled and avoided to do a good job in preventing cerebral infarction. 3, timely treatment of diseases arteriosclerosis, diabetes, coronary heart disease, hyperlipidemia, hyperviscosity, obesity, cervical spondylosis, etc. timely treatment. 4.Rational diet structure Low salt, low fat and low cholesterol are appropriate, and more soy products, vegetables and fruits are appropriate. Smoking should be avoided, alcohol should be reduced, and blood sugar and blood lipid should be checked regularly and in a targeted manner. 5, adhere to physical exercise can promote the decomposition of cholesterol to lower blood lipids, reduce the agglutination of platelets, and can relieve mental tension and fatigue. Tips: If a suspected cerebral infarction patient is found around you should be given a flat lie, head to the side, untie the patient’s collar, keep the airway open, those with dentures should try to remove them, and try to remove oral vomit or secretions. As soon as possible, take the patient directly to the emergency room or call 120 emergency number to be transported by ambulance. It is best to send the patient to a hospital with emergency conditions, emergency CT brain examination, neurologist or cerebrovascular disease specialist.
