demyelinating neuropathy
Quick Summary
Demyelinating neuropathies occur when Schwann cells, which create the myelin sheath that insulates nerve axons, are damaged or migrate away from the nerve. This loss of insulation disrupts the conduction of nerve impulses.12
These conditions can be acquired, stemming from complications of diseases like diabetes or diphtheria, or from metabolic disorders, cancers, and autoimmune attacks like in Guillain-Barré syndrome. Genetic forms, such as Charcot-Marie-Tooth disease, also exist. Symptoms vary but can include weakness, sensory changes, and pain.1324

nervous system diseaseDemyelinating and degenerative diseaseDemyelinating disease is characteristically scattered throughout the brain and spinal cord, with small foci where the myelin is destroyed and replaced with glial scar tissue. Nerve fibres running through such areas may remain undamaged, but the lack of insulation normally provided by the myelin leads…

Demyelinating diseases are characterized by the destruction of myelin surrounding nerve fibres. Although demyelination can occur after various viral infections or vaccinations, multiple sclerosis (MS) is the most common demyelinating disease.
