Once a lesion is formed in a patient with cerebral infarction, it will not disappear. A lesion means that the patient’s brain cells have died, which will be clearly shown on head CT and head MRI, and in this case the patient has to be actively treated as well. In the acute stage of cerebral infarction, the necrotic brain cells are surrounded by some ischemic brain cells, and the ischemic part of the brain cells can be saved and the blood circulation can be improved by giving the patient medication. In addition, it can also improve the symptoms of neurological deficits of patients, so that the cells without necrosis produce partial functional remodeling and improve the symptoms of patients, so it is necessary to actively carry out the treatment. Cerebral infarction belongs to the disease with high morbidity, high recurrence rate and high disability rate, and it is crucial for patients to do a good job of preventing cerebral infarction in normal times.
