Cerebral infarction has its own law of development and evolution. After cerebral infarction, there will be permanent residual lesions on imaging, and some symptoms of neurological deficiency may remain due to the non-regenerative nature of nerve cells, which we call sequelae, but overall it is still preventable and treatable. In the acute stage of cerebral infarction, revascularization treatment 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. The treatment effect is very good. Cerebral infarction is actually only a disease process, not the end of the disease, and it is necessary to make full use of modern treatment technology to clarify the causes of cerebral infarction and carry out targeted preventive treatment for the causes in order to prevent recurrence of cerebral infarction, which is also an important aspect to achieve the purpose of cure. For patients with sequelae, rehabilitation treatment should be carried out along with drug treatment to restore the patient’s motor and self-care ability, and pay attention to the patient’s psychological state to promote the patient’s return to family and society, so as to achieve the purpose of curing cerebral infarction functionally. In conclusion, although cerebral infarction is a complex process, most patients with mild disease can basically reach the standard of clinical cure through active treatment and prevention. However, it is more important to adhere to the corresponding medications as prescribed by the doctor, control the risk factors and maintain a good state of mind to prevent the recurrence of cerebral infarction.
