The prevention and treatment of cerebral infarction is a long-term process, and different treatment methods should be adopted according to different periods, and the best treatment method is to adapt to the time. Ultra-early stage: Treatment of revascularization should be carried out as early as possible to improve the blood supply in the ischemic area by means of restoring blood flow to achieve the purpose of saving brain cells, and the current treatment is diverse, and can take various ways such as intravenous thrombolysis, arterial thrombus extraction, and arterial thrombolysis. Acute phase: Patients in the acute phase have great uncertainty and rapid changes in their condition, so they should be hospitalized and treated with therapeutic measures to improve cerebral circulation and protect brain cells to try to save brain tissue and preserve neurological function. Critically ill patients should be treated with neurological monitoring. During hospitalization, the cause of cerebral infarction should be clarified as soon as possible, and therapeutic measures should be taken for the cause: antiplatelet and lipid-lowering plaque stabilization therapy should be used for atherosclerosis, and anticoagulation therapy should be used for patients with atrial fibrillation, etc. Recovery period: Patients in the recovery period mainly recover neurological function, and drug treatment is very limited, so rehabilitation treatment should be actively carried out, and at the same time, comprehensive treatment measures such as traditional Chinese medicine and acupuncture can be used to restore damaged neurological function and reduce sequelae. Posterior period: rehabilitation treatment remains the focus, strengthening daily living ability training and improving the self-care ability of seriously ill patients, meanwhile, strengthening prevention, improving lifestyle, controlling risk factors and actively preventing recurrence. In conclusion, there is no absolutely effective treatment for cerebral infarction. Currently, ultra-early, thrombolytic therapy within the time window is the best treatment, however, this time is very limited and comprehensive treatment, individualized according to different periods, may be the best solution.
