Demyelination

Demyelination (demyelination) refers to a type of disease in which the axon is relatively intact with the loss or thinning of the myelin sheath. The pathological change is the demyelination of nerve fibers and the relative intactness of nerve cells, which affects the transmission of nerve impulses. Acute demyelinating nerve myelin sheath can be regenerated, and it is relatively rapid and complete, and has little effect on functional recovery. Chronic demyelinating neuropathy, due to repeated demyelination and myelinating regenerating neural membrane cells obviously proliferate, nerves can become thick, and axons are lost, so functional recovery is incomplete.
