| acute demyelinating polyneuropathy | <neurology> A neurologic condition. Synonym: Guillain-Barre syndrome. Origin: Gr. Pathos = disease (27 Sep 1997) |
|---|---|
| chronic inflammatory demyelinating polyneuropathy | An uncommon, acquired, demyelinating sensorimotor polyneuropathy, clinically characterised by insidious onset, and slow evolution, (either steady progression or stepwise), and chronic course; symmetrical weakness is a predominant symptom, often involving proximal leg muscles, accompanied by paresthesias, but not pain; CSF examination shows elevated protein, while electrodiagnostic studies reveal evidence of a demyelinating process, primarily conduction slowing rather than block; sometimes responds to prednisone. (05 Mar 2000) |
| segmental 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) |
| 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) |
