Cerebral infarction, i.e. cerebral infarction, is a limited ischemic necrosis or softening of brain tissues due to blood circulation obstacle, ischemia and hypoxia in the brain, and the clinical symptoms depend on the size and location of infarction foci and the situation of blood vessels supplying to the brain. Clinical manifestations can be divided into three categories: (1) Typical manifestations: cerebral infarction can be sudden onset, or slow progression and aggravation, the main symptoms manifested as one side of the limb weakness, numbness, crooked tongue, slurred speech or not understand others’ speeches, etc., which are relatively common, and generally people can recognize that cerebral infarction has occurred. (2) Atypical performance: there are some patients who show dizziness, which can be a sense of heavenly rotation, or only a sense of dizziness, double vision, dysphagia or choking on drinking water, or walking to one side, hitting the door frame, or hemiplegia, or limb shaking and other atypical performances, which are in fact some special parts of the cerebral infarction, and this kind of infarction is atypical, but it’s often more easy to This type of infarction is atypical, but the condition is often more prone to change and should be noted. (3) Critical performance: if the area of cerebral infarction is large or the key part of cerebral infarction occurs, it will lead to confusion or even coma, and it may also involve the respiratory and circulatory centers to endanger the patient’s life, and this type predicts the seriousness of the condition, and if the degree of consciousness obstruction is gradually aggravated, it indicates that the condition is progressing, and the patient should urgently seek medical treatment or rescue treatment. Cerebral infarction has high morbidity, high recurrence rate and high disability rate, and its treatment should be based on different onset periods, etiology, pathogenesis, etc. to choose the best treatment: (1) Ultra-early stage: vascular recanalization treatment should be carried out as early as possible, to improve the blood supply of ischemic area by means of restoring the blood flow, to achieve the purpose of saving the brain cells, and at present there are various means of treatment, which can be taken as intravenous thrombolysis (rt-PA thrombolysis within 4.5 hours of onset, urokinetic acid thrombolysis within 4.5 hours of onset). Currently, there are various means of treatment, such as intravenous thrombolysis (rt-PA thrombolysis within 4.5 hours of onset, urokinase thrombolysis within 6 hours of onset), arterial thrombolysis, and endovascular intervention to extract thrombus. (2) Acute stage: the condition of acute stage of cerebral infarction is unstable and the infarction is easy to progress and aggravate, so it should be hospitalized. During the hospitalization, the cause of cerebral infarction should be clarified as soon as possible, and appropriate treatment measures should be taken according to the cause of the infarction: for example, atherosclerosis patients should be treated with antiplatelet aggregation and lipid-lowering to stabilize plaques, and anticoagulation should be used in atrial fibrillation. At the same time, it is supplemented with comprehensive treatment measures such as improving cerebral circulation and nourishing brain cells, so as to try to save brain tissues and preserve neurological functions. Serious patients should be treated with neurological supervision. (3) Recovery period: patients in the recovery period are mainly concerned with the recovery of nerve function and the control of risk factors. Rehabilitation therapy should be actively carried out, and at the same time, it can be supplemented with comprehensive treatment measures such as traditional Chinese medicine and acupuncture to restore the damaged nerve function and alleviate the after-effects. (4) Post-episodic period: Rehabilitation therapy is still the focus, keeping a good mindset, strengthening daily life ability training, improving the self-care ability of severe patients, meanwhile, attention should be paid to improving lifestyle, controlling risk factors, and actively preventing recurrence. In conclusion, cerebral infarction will show various symptoms, and should seek medical treatment in time. At present, ultra-early thrombolysis and endovascular intervention within the time window is the best treatment, but this time is very limited, and the treatment of cerebral infarction should be based on the etiology, onset time and other choices of individualized treatment plan and comprehensive treatment.
