After cerebral infarction, there will be permanent residual lesions on imaging and some symptoms of neurological deficits may remain due to the non-regenerative nature of nerve cells, which we call sequelae, but they are generally 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 to the ischemic area by means of restoring blood flow, so as to save brain cells. At present, there are various ways such as intravenous thrombolysis, arterial thrombus retrieval and arterial thrombolysis, etc. Moreover, due to the progress of technology, endovascular treatment technology is gradually improved, and the occluded blood vessels can be recanalized within a short period of time to preserve the neurological function to the maximum extent and achieve a good curative effect. Cerebral infarction is actually only a disease process, not the end of the disease. It is necessary to clarify the causes of cerebral infarction, and to 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 can 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 although most patients with mild disease can achieve clinical cure through active treatment and prevention, they need to 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.
