NMOSD develops primarily in women of childbearing age, and several previous studies have shown that the disorder may increase the risk of miscarriage. However, there are no reports, to our knowledge, of fetal malformation, other than neonatal hydrocephalus, related to NMOSD. We report a 30-year-old woman who experienced recurrent neuritis and who was seropositive for AQP4-IgG. She became pregnant, and the fetus was found to have ectrodactyly. Histological analysis of the placenta showed moderate inflammatory infiltration; however, whether fetal malformation in NMOSD is related to inflammation and AQP4-IgG remains to be determined...

Previous research indicated the association between hepatitis B virus (HBV) infection/vaccination and the onset of demyelinating diseases. However, most of these studies were single case reports, and comprehensive data are still scarce. Here we present a comprehensive analysis of 10 patients with neuromyelitis optica spectrum disorder (NMOSD) combined with chronic hepatitis B (CHB) infection and seropositive for anti-aquaporin-4 antibody (AQP4-Ab). Demographic, clinical, laboratory, neuroimaging, outcome, and follow-up data of the 10 patients were retrospectively analyzed...

We report the case of a patient who initially presented with fever, headache and seizure. MRI revealed a fluid attenuation inversion recovery (FLAIR) high-intensity lesion involving the right temporal, parietal and occipital cortex. Afterwards, the patient developed three recurrent episodes, manifested as brainstem encephalitis, optic neuritis and ADEM-like illness successively, indicating demyelination. Both of his serum anti-MOG and CSF anti-NMDAR antibodies were proved positive by transfected cell based assays...

In recent years, not only the incidence of brain demyelinating disease has increased, but also it seems that the world is facing new forms of autoimmune diseases of the brain. Distinguishing these diseases from each other is very important, since each requires a different treatment. The new criteria that were put forward in 2015 were meant to pave the way for better diagnosis of these diseases called neuromyelitis optica spectrum disease (NMOSD). However, too much emphasis on the criteria based on the convergence and association of radiological findings with the clinical symptoms actually causes confusion in the diagnosis...

BACKGROUND: Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS). The neutrophil-to-lymphocyte ratio (NLR) has been identified as a disease activity marker in several diseases. We aim to evaluate the significance of the NLR in the different subtypes of MS, optic neuritis (ON) and in relation to disease activity and Expanded Disability Status Scale (EDSS). METHODS: We included 378 patients and 813 healthy controls (HC) from The Nordic Reference Interval Project 2000 (NORIP)...

Neuromyelitis Optica Spectrum Disorder (NMOSD) is a relapsing neuro inflammatory disease of the central nervous system that typically presents with optic neuritis or myelitis and may cause severe disability. The diagnostic criteria have been updated and several immunosuppressive agents have been demonstrated to prevent acute exacerbations. As the disease rarely develops in a progressive course, management of acute attacks and proper prevention of exacerbations may change the long term out-come and prevent future disability...

Neuromyelitis optica (NMO) and NMO spectrum disorder (NMOSD) is a rare relapsing autoimmune disease of the central nervous system constituting less than 1% of demyelinating diseases (Jeffery and Buncic, 1996). It preferentially affects the optic nerves and spinal cord, with the brain parenchyma generally spared. Demyelinating lesions are characterised by longitudinally extensive transverse myelitis (LETM) and often longitudinally extensive optic neuritis. Following the discovery of a novel pathogenic antibody, Aquaporin 4 in 2004 (Lennon et al...

The incidence of neuromyelitis optica spectrum disorders (NMOSD) in the Asian population is much higher than in Europe and North America. Optic neuritis is the first sign of NMOSD for some people. Identification of aquaporin 4 antibody is a milestone in the research of NMOSD and has been included in the diagnosis standard of NMOSD, but about 20% to 30% of NMOSD patients is aquaporin 4 antibody-negative. With the cell-based assays, oligodendrocyte glycoprotein antibodies in demyelinating diseases of the central nervous system have aroused the attention of researchers...

A condition associated with an autoantibody against MOG has been recently recognized as a new inflammatory disease of the central nervous system, but the disease course and disability outcomes are largely unknown. In this study we investigated clinical characteristics of MOG-antibody disease on a large cohort of patients from the UK. We obtained demographic and clinical data on 252 UK patients positive for serum immunoglobulin G1 MOG antibodies as tested by the Autoimmune Neurology Group in Oxford. Disability outcomes and disease course were analysed in more detail in a cohort followed in the Neuromyelitis Optica Oxford Service (n = 75), and this included an incident cohort who were diagnosed at disease onset (n = 44)...

BACKGROUND: Patients with an acute unilateral peripheral vestibular deficit (aUPVD), presumed to be caused by vestibular neuritis, show asymmetrical vestibular ocular reflexes (VORs) that improve over time. Questions arise regarding how much of the VOR improvement is due to peripheral recovery or central compensation, and whether differences in peripheral recovery influence balance control outcomes. METHODS: Thirty patients were examined at aUPVD onset and 3, 6, and 13 weeks later with four different VOR tests: caloric tests; rotating (ROT) chair tests performed in yaw with angular accelerations of 5 and 20 degrees/s; and video head impulse tests (vHIT) in the yaw plane...

OBJECTIVE: Over the last decade, ocular vestibular evoked myogenic potentials (oVEMPs) have evolved as a new clinical test for dynamic otolith (predominantly utricular) function. The aim of this review is to give an update on the neurophysiological foundations of oVEMPs and their implications for recording and interpreting oVEMP responses in clinical practice. CONCLUSION: Different lines of anatomical, neurophysiological, and clinical evidence support the notion that oVEMPs measure predominantly contralateral utricular function, while cervical cVEMPs are an indicator of ipsilateral saccular function...

Neuromyelitis optica spectrum disorders (NMOSD) are demyelinating, autoimmune diseases affecting the central nervous system. Typically, recurrent optic neuritis and longitudinal extensive transverse myelitis dominates the clinical picture. In most cases NMOSD are associated with autoantibodies targeting the water channel aquaporin-4 (AQP-4). NMOSD usually present in young adults. Clinical findings suggestive of NMOSD in elderly patients should raise the suspicion of a paraneoplastic etiology. To our knowledge, we report the first case of a 66 year-old female patient with paraneoplastic NMOSD that is associated with squamous cell lung carcinoma...

Objective: Many previous studies have demonstrated that neuromyelitis optica (NMO) patients have abnormalities of brain anatomy and function. However, differences in spontaneous brain activity between myelin oligodendrocyte glycoprotein (MOG)-IgG ON and aquaporin 4(AQP4)-neuromyelitis optica-optic neuritis (ON) remain unknown. In the current study, we investigated the brain neural homogeneity in MOG-IgG ON versus AQP4-IgG NMO-ON subjects by regional homogeneity (ReHo) method using magnetic resonance imaging (MRI)...

Neuromyelitis optica spectrum disorders (NMOSD) are mostly relapsing inflammatory conditions of the central nervous system (CNS). In 55% of the cases of NMOSD optic neuritis (ON) is the most frequent first manifestation and can cause severe damage to the afferent visual system and the retina with resultant severe visual impairment. In recent years, investigations of the retina as part of the CNS by optical coherence tomography (OCT) has been shown to be a valid and efficient method for diagnostics and evaluation of the disease course in NMOSD...

Objectives: Optic neuritis (ON) can occur in isolation or association with multiple sclerosis (MS) or neuromyelitis optica. ON, is seen more commonly in Caucasians and interaction is found to exist between ethnic origin and the latitude at which the patient grows up. At present limited information is available about the profile of ON in Saudi patients. We aimed to analyze the records of ON patients, in regard to their presentation, natural history, treatment outcome, and risk and association with MS...
