A 53-year-old woman was admitted to the department of neurology in Tenri Hospital because of progressive thoracic myelitis a month after she had eaten uncooked bovine liver. A previous episode of right optic neuritis and a positive test for serum anti-aquaporin-4 antibodies indicated a diagnosis of neuromyelitis optica spectrum disorders. Although the patient initially recovered with the reduction of anti-aquaporin-4 antibodies during treatment with intravenous methylprednisolone infusion and plasma exchange, her neurological symptoms deteriorated soon after the completion of plasma exchange...

PURPOSE: Visual electrophysiology is routinely used to detect the visual complications of multiple sclerosis, but the analysis mostly focuses on visual evoked potential (VEP) and especially the P100 component. Our goal was to analyze the components and waveform alterations of VEPs and pattern electroretinograms (PERGs) in patients with multiple sclerosis (MS) with good vision. METHODS: The main VEP and PERG components of 85 patients with MS were analyzed in two groups: 38 patients who had optic neuritis in their history (ON group) and 47 patients who had never had optic neuritis (MS group)...

Optic neuritis (ON) may rarely mimic optic nerve tumor, index of suspicion should be kept high. A 34-year-old woman presented to a major academic institute with a history of right-sided ocular pain and progressive visual loss in the same eye. Her magnetic resonance imaging showed markedly thickened optic nerve; her workup for inflammatory pathology was negative; she was diagnosed as a case of optic nerve tumor and was planned for surgery. Patient for second opinion came to a tertiary care institute where on proper history taking and evaluation she was diagnosed and treated on the lines of ON and she improved...

Premise This review summarises the pain syndromes that overlap between headache and facial pain and overlap between pain and cranial nerve lesion. Problem These syndromes share two features in common. First, they show both cranial nerve impairment (e.g. palsy, autonomic dysfunction) and pain; second, they have inflammatory (and/or small vessel) processes as the underlying mechanism. A typical representative of these syndromes is recurrent painful ophthalmoplegic neuropathy, which was previously called ophthalmoplegic migraine and was regarded as a migraine subtype...

The objective of this paper is to evaluate the association between physical disability in multiple sclerosis (MS) patients, the thickness of the retinal nerve fibre layer (RNFL) and corpus callosum volumes, as expressed by the corpus callosum index (CCI). This study was based on a cohort of 212 MS patients and 52 healthy control subjects, who were age and gender matched. The MS patients included 144 women and 177 relapsing-remitting MS (RRMS) patients. Peripapillary and volumetric optical coherence tomography (OCT) scans of the macula were performed using spectral-domain OCT technology...

BACKGROUND: While many groups use experimental autoimmune encephalomyelitis (EAE) as a model to uncover therapeutic targets and understand the pathology underlying multiple sclerosis (MS), EAE protocol variability introduces discrepancies in central nervous system (CNS) pathogenesis and clinical disease, limiting the comparability between studies and slowing much-needed translational research. OPTIMIZED METHOD: Here we describe a detailed, reliable protocol for chronic EAE induction in C57BL/6 mice utilizing two injections of myelin oligodendrocyte glycoprotein (35-55) peptide mixed with Complete Freund's Adjuvant and paired with pertussis toxin...

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that can affect different ocular structures, such as cornea, conjunctiva, episclera, sclera, uveal tract, retina, optic nerve and vessels. Neuro-ophthalmologic manifestations in SLE include different degrees of involvement of retina, choroid and optic nerve. Retinal changes are one of the most common ocular involvements and are frequently used as clinical criteria for activity, even if isolated. Studies show that up to 29% of patients with active SLE manifest retinal disease...

The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is a potential cause of hyponatremia of the central nervous system (CNS). Although SIADH has been reported to be associated with many other central nervous disorders, its association with neuromyelitis optica (NMO) or NMO spectrum disorders are rare. NMO is a demyelinating disorder characterized by optic neuritis and transverse myelitis. Aquaporin-4 (AQP4), which is the target antigen for a NMO autoantibody, is the predominant CNS water channel...

Neuromyelitis optica (NMO) is clinically characterized by severe optic neuritis and transverse myelitis, but recent studies with anti-aquaporin-4-antibody specific to NMO have revealed that the clinical spectrum is wider than previously thought. International consensus diagnostic criteria propose NMO spectrum disorders (NMOSD) as the term to define the entire spectrum including typical NMO, optic neuritis, acute myelitis, brain syndrome, and their combinations. NMOSD is now divided into anti-aquaporin-4-antibody-seropositive NMOSD and -seronegative NMOSD (or unknown serostatus)...

Takayasu arteritis (TA) is a systemic vasculitis of unknown etiology that affects the aorta and its primary branches or large arteries in the proximal upper or lower extremities. Ocular manifestations of TA include microaneurysm formation, small-vessel dilation, arteriovenous anastomosis, retinal ischemia, and neovascular glaucoma. We herein report a case involving a 23-year-old Asian woman who presented with isolated acute anterior ischemic optic neuropathy and was initially misdiagnosed with optic neuritis...

BACKGROUND: Magnetic resonance imaging markers have been widely used to detect and quantify white matter pathologies in multiple sclerosis. We have recently developed a diffusion basis spectrum imaging (DBSI) to distinguish and quantify co-existing axonal injury, demyelination, and inflammation in multiple sclerosis patients and animal models. It could serve as a longitudinal marker for axonal loss, a primary cause of permanent neurological impairments and disease progression. METHODS: Eight 10-week-old female C57BL/6 mice underwent optic nerve DBSI, followed by a week-long recuperation prior to active immunization for experimental autoimmune encephalomyelitis (EAE)...

Myelin oligodendrocyte glycoprotein is a protein exclusively expressed on the surface of oligodendrocytes and myelin in the central nervous system. Antibodies against myelin oligodendrocyte glycoprotein were initially detected in children with demyelinating syndromes, and more recently reported in a broad spectrum of central nervous system demyelinating diseases in adults, including neuromyelitis optica spectrum disorders and bilateral optic neuritis. Patients with myelin oligodendrocyte glycoprotein antibody-associated demyelination appear to have unique clinical and radiological features...

Retinae of patients with multiple sclerosis (MS), as part of the central nervous system (CNS), display inflammatory and neurodegenerative changes. There is increasing evidence suggesting that retinal changes, and in particular neurodegeneration, mirror global CNS alterations in MS. Spectral domain optical coherence tomography (SD-OCT) is an inexpensive, rapid, non-invasive, and reproducible imaging technique that generates high-resolution images of tissues such as the retina. An advantage of SD-OCT over magnetic resonance imaging techniques in the assessment of neurodegeneration may be its sensitivity to capture changes at the individual patient level...

PURPOSE: To report a case of systemic lupus erythematosus-induced choroidal vasculitis. METHODS: A 34-year-old woman with a long-standing history of systemic lupus erythematosus had a sudden painless loss of vision in the right eye over 12 hours. Ocular examination revealed a visual acuity of counting fingers of 1 foot on the right eye and 20/20 on the left. There was a relative afferent pupillary defect on the right side with a pink, distinct optic disk margin...

Glaucoma causes a decrease in peripapillary perfused capillary density on optical coherence tomography (OCT) angiography. However, other chronic optic neuropathies have not been explored with OCT angiography to see if these changes were specific to glaucoma. The authors evaluated OCT angiography in 10 patients who suffered various kinds of chronic optic neuropathies, including optic neuritis and ischaemic optic neuropathy, and found that all optic neuropathies showed a decrease in peripapillary vessel density on OCT angiography, regardless of the aetiology of the optic neuropathy...

Recent work from our laboratory, using different models of experimental neuromyelitis optica spectrum disorder (NMOSD), has led to a number of observations that might be highly relevant for NMOSD patients. For example: (i) in the presence of neuromyelitis optica immunoglobulin G, astrocyte-destructive lesions can be initiated by CD4+ T cells when these cells recognize aquaporin 4 (AQP4), but also when they recognize other antigens of the central nervous system. The only important prerequisite is that the T cells have to be activated within the central nervous system by "their" specific antigen...

Most children who experience an acquired demyelinating syndrome of the central nervous system will have a monophasic disease course, with no further clinical or radiological symptoms. A subset will be diagnosed with multiple sclerosis, a life-long disorder. Using linear mixed effects models we examined longitudinal diffusion properties of normal-appearing white matter in 505 serial scans of 132 paediatric participants with acquired demyelinating syndromes followed for a median of 4.4 years, many from first clinical presentation, and 106 scans of 80 healthy paediatric participants...
