Demyelination has damaged the nerves making it more difficult to treat. Demyelination is mainly the loss of myelin from the nerves. If demyelination has damaged the nerves, it means that the myelin sheath is severely damaged, and it is possible that the damage caused to the nerves is irreversible, difficult to repair or regenerate, and usually difficult to cure. However, patients still need to cooperate with professional neurologists for standardized treatment, which can alleviate the condition and avoid further development. If demyelination has already damaged the nerves, it must be taken seriously and it is recommended to go to the neurology department of a regular hospital as soon as possible to control the condition in time. Even if the condition is under control, it should not be taken lightly and should be reviewed regularly to avoid recurrence of the disease. During the treatment period, patients should pay attention to rest, to ensure adequate sleep, not too tired, and at the same time to strengthen the diet and nutrition, maintain a light diet.
