1 Special Contribution Eun Hee Ha, MD Department of Preventive Medicine, Ewha Womans University College of Medicine E mail : eunheeha@ewha.ac.kr J Korean Med Assoc 2007; 50(2): 1-1 Abstract ultiple Sclerosis (MS) is the commonest demyelinating disease affecting the central nervous system of young Madults living in the western world. The clinical suspicion of demyelination, as a pathological process, is high when a young adult develops one or more neurological episodes consistent with damage to white matter tracts within the central nervous system, especially when these affect the optic nerves, brainstem or spinal cord. The patient with episodes disseminated in time, each of which can be attributed to demyelination, requires no investigation prior to establishing the diagnosis of clinically definite MS if presentation occurs between the ages of 20 and 50 years, separate anatomical sites within the central nervous system have necessarily been affected on different occasions, and the clinical phenotype is typical for multiple sclerosis. MS in Asian populations is characterized by the selective and dominant involvement of the optic nerve and spinal cords, as well as some incidence of brainstem lesion and symptoms % of cases of MS in Korea are of this optico-spinal type. Opticospinal MS (OSMS) generally has a higher female to male ratio than conventional MS. OSMS is also characterized by frequent relapses, severe disability, few brain lesions on MRI and an very lower incidence of oligoclonal bands in the CSF. Neuromyelitis Optica (NMO) (Devic syndrome), causing severe optic neuritis (ON) and longitudinally extensive transverse myelits either with monophase or relapse remitting pattern, is rare in Korea. NMO- IgG was reported to help diagnose early stage of NMO and differentiation of MS. Keywords : Demyelinating disease; Multiple sclerosis; Neuromyelitis Optica; NMO-IgG; Opticospinal MS 1
