Neuromyelitis optica is a rare inflammatory, demyelinating disease of the central nervous system that predominantly targets the optic nerves and spinal cord. Our case represents an unusual and severe course of neuromyelitis optica. Despite several forms of treatment, our patient died after a severe and short-term attack.

Neuromyelitis optica and neuromyelitis optica spectrum disorders have been recently associated with the disease-specific autoantibody aquaporin-4, thought to be pathogenic. Identifying this antibody has allowed the clinical phenotype to be broadened. It is clear that some patients with similar clinical features do not have this antibody and may have a different condition with different outcomes...

PURPOSE OF REVIEW Pediatric inflammatory demyelinating central nervous system diseases comprise monofocal and potentially monophasic disorders like optic neuritis and transverse myelitis, the multifocal, self-limiting disorder of acute disseminated encephalomyelitis, and multifocal chronic diseases like relapsing neuromyelitis optica and multiple sclerosis. This review discusses characteristics...

BACKGROUND Neuromyelitis optica is a severely disabling inflammatory disorder of the central nervous system of autoimmune etiology that mainly affects the optic nerves and spinal cord. Here, we present a case report detailing a patient with tingling and weakness of right upper and lower limbs who was neuromyelitis optica immunoglobulin G-positive. CASE PRESENTATION A 46-year-old Nepalese man ...

BACKGROUND There is increasing recognition of antibody-mediated immunotherapy-responsive neurologic diseases and a need for appropriate immunoassays. OBJECTIVES To develop a clinically applicable quantitative assay to detect the presence of aquaporin-4 (AQP4) antibodies in patients with neuromyelitis optica and to characterize the anti-AQP4 antibodies. DESIGN We compared a simple new quanti...

Devic's neuromyelitis optica is a rare syndrome characterised by the combination of acute or subacute optic neuritis and transverse myelitis, in some cases considered to be a variant of multiple sclerosis. Mutations of mitochondrial DNA (mtDNA) associated with Leber hereditary optic neuropathy (LHON) have been identified in some patients with multiple sclerosis in whom optic neuritis is a promi...

clinical examination, magnetic resonance imaging, cerebrospinal findings and positive aquaporin-4 antibodies, which are highly specific and sensitive for this condition. The serum autoantibody NMO-immunoglobulin G was reported as a biomarker of neuromyelitis optica in 2004. Viral prodrome often precedes the onset of disease, suggesting that infectious agents may cause or trigger NMO. Many disea...

BACKGROUND Although overt involvement of the central nervous system (CNS) in myasthenia gravis (MG) is considered rare, hyperreflexia is a common and yet unexplained finding. Aquaporin 4 (AQP4), the target autoantigen in neuromyelitis optica, is expressed both in the CNS and in the neuromuscular junction. OBJECTIVES To evaluate the prevalence of even mild CNS involvement in patients with MG a...

Neuromyelitis optica antibody (or aquaporin-4 antibody) is a well established serum marker associated to high-risk neuromyelitis optica syndrome that presents as an inflammatory demyelinating disease characterized by the occurrence of bilateral and simultaneous optic neuritis without complete visual recovery or it occurs as an isolated episode of transverse myelitis accompanied by longitudinall...
