| demyelinated myelitis | Acute multiple sclerosis presenting as a myelitis. (05 Mar 2000) |
| demyelinating disease | Diseases in which the myelin sheath of nerves is destroyed and that often have an autoimmune component. Examples are multiple sclerosis, acute disseminated encephalomyelitis (a complication of acute viral infection), experimental allergic encephalomyelitis, Guillain-Barre syndrome. (18 Nov 1997) |
| demyelinating diseases | Any condition characterised by the destruction of myelin and extensive loss of the myelin sheaths of the nerve fibres. It affects both the central and peripheral nervous systems. Its aetiology is at present unknown. (12 Dec 1998) |
| demyelinating encephalopathy | Extensive idiopathic loss of myelin sheaths in the brain, as occurs in leukodystrophy. (05 Mar 2000) |
| demyelinating polyneuropathy | A type of polyneuropathy in which almost solely the peripheral nerve myelin is affected; can be both familial (e.g., Charcot-Marie Tooth disease, type 1), or acquired (e.g., Guillain-Barre syndrome); on motor nerve conduction studies, manifested as conduction slowing or block. Synonym: segmental demyelinating polyneuropathy. (05 Mar 2000) |
| demyelination | Loss of myelin with preservation of the axons or fibre tracts. Central demyelination occurs within the central nervous system (e.g., the demyelination seen with multiple sclerosis); peripheral demyelination affects the peripheral nervous system (e.g., the demyelination seen with Guillain-Barre syndrome). (05 Mar 2000) |
| demyelinisation | The destruction of the protective myelin sheath that surrounds nerve fibres, resulting in the loss of function of those nerves. Demyelinisation happens in some degenerative nerve diseases like multiple sclerosis and polio. (09 Oct 1997) |
