Cerebral infarction has its own developmental pattern. After cerebral infarction, there will be permanent residual lesions in imaging, and some sequelae may remain due to the non-regenerative nature of nerve cells, but mild patients may not have any sequelae. Cerebral infarction is generally preventable and treatable. In the acute stage of cerebral infarction, the 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 means are various, such as intravenous thrombolysis, arterial thrombosis, arterial thrombolysis, etc. Moreover, due to the progress of technology, the endovascular treatment technology is gradually improved, and the occluded blood vessels can be reopened within a short period of time to preserve the neurological function to the greatest extent. In addition, due to the progressive improvement of endovascular treatment technology, the occluded blood vessel can be recanalized within a short period of time, and the neurological function can be preserved to the greatest extent. In addition, cerebral infarction is actually only a disease process, not the end of the disease, and it is important 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, along with drug treatment, rehabilitation treatment should be carried out 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 the family and society, so as to achieve the purpose of curing cerebral infarction functionally. In conclusion, cerebral infarction is a complex process, and most patients with mild disease can reach the standard of clinical cure through active treatment and prevention, but they should adhere to the corresponding medications as prescribed by the doctor, control the risk factors, and maintain a good state of mind to prevent recurrence of cerebral infarction.
