CNS demyelination is generally associated with ischemia, metabolic disorders, immune inflammation, and other factors. It can be treated by oral aspirin, injection of cerebroside myelopeptide solution, plasma exchange, and so on. 1. Ischemia: such as insufficient blood supply to the brain, causing demyelination ischemia, leading to central nervous demyelination. It can be treated by taking oral aspirin, atorvastatin and other drugs to improve ischemic symptoms and treat CNS demyelination. 2. Metabolic disorders: Generally, the development of myelin sheath is impaired, which leads to CNS demyelination. Oral vincristine tablets and injection of cerebroside myelin solution can be used to improve brain metabolism and treat CNS demyelination. 3. Immune inflammation: When viral infections occur, they can induce a neurological autoimmune response, leading to CNS demyelination. CNS demyelination can be treated by plasma exchange. It is recommended that patients go to the hospital in time to see a doctor to clarify the cause of the disease and then treat it correctly.
