Cerebral infarction is ischemic necrosis or cerebral softening of limited brain tissue caused by impaired blood supply to the brain, ischemia and hypoxia. The common clinical types of cerebral infarction are cerebral thrombosis, lacunar infarction and cerebral embolism, etc. Several diseases that are more correlated with cerebral infarction are: diabetes, obesity, hypertension, rheumatic heart disease, cardiac arrhythmia, dehydration of various causes, various arteritis, shock, and too rapid and too large a drop in blood pressure. Cerebral infarction is usually manifested by sudden fainting and unconsciousness, commonly with distorted mouth and eyes, unfavorable speech, hemiplegia, etc. Most of those prone to cerebral infarction are middle-aged and elderly. The specific types are described as follows: cerebral thrombosis (thrombotic cerebral infarction) Cerebral thrombosis, which is a kind of cerebral infarction, is a disease caused by atherosclerosis of cerebral arteries, resulting in gradual narrowing or even complete occlusion of the inner lumen of blood vessels. Due to the formation of thrombus in the cerebral vessels, the blood supply to the local brain tissue is insufficient and further softened and necrotic. The symptoms vary depending on the location of thrombus formation in the brain. Cerebral thrombosis has the highest incidence among cerebral infarction, accounting for more than half of all cases of cerebral infarction, and is more common in middle-aged and elderly people, more men than women, mostly in a quiet state. The clinical symptoms of cerebral thrombosis and cerebral hemorrhage have many similarities and are easily confused, but the treatment options are diametrically opposed. The former requires hemolysis, while the latter requires coagulation. The prognosis of cerebral thrombosis is better than cerebral hemorrhage, but some patients may have sequelae such as hemiplegia. Cerebral embolism (embolic cerebral infarction) Cerebral embolism is very different from cerebral thrombosis, because its primary cause is not in the brain, but the “embolus” formed in other parts of the body (mostly heart and limb blood vessels) enters the blood vessels and flows into the cerebral arteries, blocking the lumen, which causes cerebral embolism and localized ischemia and softening of brain tissue, resulting in the same consequences as cerebral thrombosis. What is “embolism”? There are blood clots, fat, air, and superfluous organisms on the heart valves. The incidence of cerebral embolism is also very high, and it is common in young and middle-aged people. The symptoms are similar to those of cerebral thrombosis, including headache, vomiting, unconsciousness, hemiparesis, etc. Patients with a history of rheumatic heart disease, atrial fibrillation, subacute bacterial endocarditis, etc. are more likely to suffer from cerebral embolism than others. Cerebral lacunar infarction (lacunar cerebral infarction) Lacunar cerebral infarction is a special type of cerebral infarction, which is an ischemic softening lesion of brain tissue caused by occlusion of tiny arteries deep in the brain on the basis of hypertension and arterial infarction. Patients mostly have no obvious symptoms or only mild inattention, memory loss, mild headache and dizziness, vertigo, and slow reaction and other symptoms. The diagnosis of this disease is mainly based on CT or MRI, and multiple lacunar cerebral infarcts can affect brain function, leading to progressive mental decline and eventually cerebrovascular dementia. The following measures should be taken to prevent and treat lacunar cerebral infarction: patients with hypertension should be treated with long-term medication and blood pressure should be measured regularly to keep blood pressure in the normal range; diabetic patients should strictly control their diet and insist on glucose-lowering treatment to keep blood sugar in the normal range; patients with hyperlipidemia should be treated with lipid-lowering treatment; regular blood rheological examination should be conducted, and those with high blood viscosity should take small doses of oral aspirin; regular cardiac examination should be conducted, especially Pay attention to changes in cardiac function and arrhythmia, improve blood supply to the heart and prevent coronary heart disease; be alert to sudden onset of headache, dizziness, vertigo, memory loss, slow reaction, forgetfulness, blurred vision, facial numbness and other symptoms, and go to the hospital for cranial CT as early as possible for early detection and treatment; Chinese herbal medicines with blood circulation, aromatic enlightenment, lipid-lowering and anticoagulant effects have a comprehensive effect on the causes of lacunar cerebral infarction. The preventive and curative effects can prevent recurrence while improving symptoms when taken consistently. Multiple cerebral infarction Multiple cerebral infarction refers to multiple foci of ischemic softening in the brain, also known as multiple cerebral softening. In addition to the common paralysis, sensory ability and language impairment, dementia may also occur, which is called multi-infarct dementia (i.e. atherosclerotic dementia), and is common in middle-aged and elderly people. The more lesions in this disease, the higher the incidence of dementia, and bilateral infarcts are more prone to dementia than unilateral ones, so the recurrence of cerebral infarction should be actively prevented.
