Visual imaging as a predictor of neurodegeneration in experimental autoimmune demyelination and multiple sclerosis.

Acta Neuropathol Commun 2022 Jun 15;10(1):87. Epub 2022 Jun 15.

Department of Neurosciences, Lerner Research Institute, Cleveland Clinic Foundation, and Case Western Reserve University, 9500 Euclid Avenue, Cleveland, OH, 44195, USA.

Thalamic volume is associated with clinical disability in multiple sclerosis (MS) and is vulnerable to secondary neurodegeneration due to its extensive connectivity throughout the central nervous system (CNS). Using a model of autoimmune demyelination that exhibits CNS-infiltrating immune cells in both spinal cord white matter and optic nerve, we sought to evaluate neurodegenerative changes due to lesions affecting the spino- and retino-thalamic pathways. We found comparable axonal loss in spinal cord white matter and optic nerve during the acute phase of disease consistent with synaptic loss, but not neuronal cell body loss in the thalamic nuclei that receive input from these discrete pathways.

Case Report: Neuromyelitis Optica Spectrum Disorder With Progressive Elevation of Cerebrospinal Fluid Cell Count and Protein Level Mimicking Infectious Meningomyelitis: A Diagnostic Challenge.

Front Immunol 2022 19;13:864664. Epub 2022 May 19.

Department of Neurology, Tongde Hospital of Zhejiang Province, Hangzhou, China.

Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune-mediated idiopathic inflammatory demyelinating disease with a typical clinical presentation of optic neuritis, acute myelitis, and area postrema syndrome. Most NMOSD patients are seropositive for disease-specific and pathogenic aquaporin-4 (AQP4) antibodies, which are key markers for the NMOSD diagnosis. Herein, we report an atypical case of a 41-year-old man who complained of intractable hiccups and vomiting at disease onset, followed by fever, headache, back pain, progressive paresthesia, and weakness of extremities later on.

Neuromyelitis optica spectrum disorder: do patients positive and negative for anti-aquaporin-4 antibodies present distinct entities? A Colombian perspective.

Neurologia (Engl Ed) 2022 May 28. Epub 2022 May 28.

Servicio de Neurología, Fundación Cardioinfantil-Instituto de Cardiología, Bogotá, Colombia; Universidad del Rosario, Grupo Neuros, Bogotá, Colombia; Hospital Universitario Mayor, Mederi, Bogotá, Colombia.

Introduction: Neuromyelitis optica (NMO) is an inflammatory disease of the central nervous system characterised by attacks of optic neuritis and longitudinally extensive transverse myelitis. The discovery of anti-aquaporin-4 (anti-AQP4) antibodies and specific brain MRI findings as diagnostic biomarkers have enabled the recognition of a broader and more detailed clinical phenotype, known as neuromyelitis optica spectrum disorder (NMOSD).

Objective: This study aimed to determine the demographic and clinical characteristics of patients with NMO/NMOSD with and without seropositivity for anti-AQP4 antibodies, in 2 quaternary-level hospitals in Bogotá. Read More

[Optical coherence tomography in the differential diagnostics of important neuro-ophthalmological disease patterns].

Nervenarzt 2022 Jun 25;93(6):629-642. Epub 2022 May 25.

Universitäts-Augenklinik, Department für Augenheilkunde, Universitätsklinikum Tübingen, Elfriede-Aulhorn-Straße 7, 72076, Tübingen, Deutschland.

There are many disease patterns that are treated jointly by neurologists and ophthalmologists, for which optical coherence tomography (OCT) is of important differential diagnostic significance. In this context neurologists are mainly confronted by two patient collectives: patients with an acute ischemic event, who present with an acute but painless monocular visual deterioration (for central retinal artery occlusion) or with a monocular visual field defect (for arterial branch occlusion or anterior ischemic optic neuropathy). The second collective is patients without ophthalmological symptoms but with conspicuous optic nerve findings (papilledema or optic disc drusen). Read More

Development and validation of a simple and practical method for differentiating MS from other neuroinflammatory disorders based on lesion distribution on brain MRI.

J Clin Neurosci 2022 Jul 4;101:32-36. Epub 2022 May 4.

NYU MS Comprehensive Care Center, Department of Neurology, New York University Grossman School of Medicine, New York, NY, USA.

There is an unmet need to develop practical methods for differentiating multiple sclerosis (MS) from other neuroinflammatory disorders using standard brain MRI. To develop a practical approach for differentiating MS from neuromyelitis optica spectrum disorder (NMOSD) and MOG antibody-associated disorder (MOGAD) with brain MRI, we first identified lesion locations in the brain that are suggestive of MS-associated demyelination ("MS Lesion Checklist") and compared frequencies of brain lesions in the "MS Lesion Checklist" locations in a development sample of patients (n = 82) with clinically definite MS, NMOSD, and MOGAD. Patients with MS were more likely than patients with non-MS to have lesions in 3 locations only: anterior temporal horn (p < 0. Read More

Systemic Lupus Erythematous and Neuromyelitis Optica Causing Hypercapnic Respiratory Failure.

Am J Case Rep 2022 May 1;23:e936283. Epub 2022 May 1.

Division of Academic Affairs and Research, Orlando Regional Healthcare, Orlando, FL, USA.

BACKGROUND Neuromyelitis optica (NMO) is a rare neurological disease characterized by attacks of transverse myelitis and optic neuritis, contiguous spinal cord lesions on more than 3 vertebral segments on magnetic resonance imaging (MRI), and seropositivity for AQP-4 Ab. The tissue destruction from NMO is immune mediated and results in demyelination and axonal damage. Optic and spinal nerve involvement can eventually lead to blindness, weakness, and altered consciousness, and bladder and bowel involvement in some cases. Read More
