Can brain nerve damage be completely restored?

Can cranial nerve damage be completely recovered? The analysis is as follows: The prognosis of the disease should be judged based on the cause of cranial nerve damage. After cranial nerve damage, there will be bleeding and brain barrier destruction, cerebral ischemia, hypoxia, and brain edema. Or serious problems such as local circulatory disorders and increased intracranial pressure should be treated promptly, otherwise the condition will be further worsened. After cranial nerve injury, there is no complete recovery, and only partial function can be restored. In addition, patients with brain nerve damage, the specific degree of recovery, and the severity of the patient's condition, patient age, physique and other factors related. If the condition is relatively mild, timely receive standardized treatment, the patient's own physique is better, the later recovery effect is relatively better. Conversely, the condition is more serious, older, weaker patients, recovery effect will be worse.
