The hospital neurologist is often consulted to coordinate the evaluation and management of a host of known or suspected demyelinating diseases. Among the most common are multiple sclerosis, acute disseminated encephalomyelitis, optic neuritis, and transverse myelitis.

AbstractAcquired demyelinating syndromes (ADS) present with acute or subacute monofocal or polyfocal neurologic deficits localizing to the central nervous system. The clinical features of distinct ADS have been carefully characterized including optic neuritis, transverse myelitis, and acute disseminated encephalomyelitis. These disorders may all be monophasic disorders. Alternatively, optic neuritis, partial transverse myelitis, and acute disseminated encephalomyelitis may be first presentations of a relapsing or polyphasic neuroinflammatory disorder, such as multiple sclerosis or neuromyelitis optica. The clinical features of these disorders and the differential diagnosis are discussed in this article.

Relapsing Remitting

Multiple sclerosis (MS) is a relatively common cause of neurologic symptoms and disability in young adults. The distinguishing pathologic features of MS are loss of myelin and inflammation in the central nervous system (CNS). The myelin sheath is essential for rapid conduction of nerve signals along large-diameter axons. Oligodendrocytes produce and maintain myelin in the CNS, and Schwann cells produce and maintain myelin in the peripheral nerves. In addition to MS, there are a number of related disorders causing demyelination, inflammation, or both in the CNS. This chapter discusses MS and related disorders, including neuromyelitis optica, optic neuritis, acute disseminated encephalomyelitis, transverse myelitis, Behçet syndrome, neurosarcoidosis, inherited demyelinating diseases (leukodystrophies, cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy [CADASIL]), and virus-induced demyelination (progressive multifocal leukoencephalopathy, subacute sclerosing panencephalitis). The section on MS covers epidemiology, etiology/genetics, pathogenesis, diagnosis, differential diagnosis, management, and prognosis. Figures include organization of the microenvironment of larger-diameter axons, typical magnetic resonance imaging findings in MS and neuromyelitis optica, postgadolinium images of the cervical spine in MS, and an approach to treatment of relapsing-remitting MS. Tables list MS and related disorders, distribution of neurologic deficits at the onset of MS, differential diagnosis of MS, disease-modifying therapies for relapsing-remitting MS, and selected leukodystrophies, as well as diagnostic criteria and selected symptomatic therapies for MS. This review contains 3 highly rendered figures, 7 tables, and 82 references.

The Central Nervous System

Neuromyelitis optica (NMO), or Devic’s disease is an inflammatory disorder of the central nervous system that preferentially affects the optic nerves and spinal cord. Initially considered a variant of multiple sclerosis (MS), NMO is now clearly recognized to have distinct clinical, radiographic, and pathologic characteristics. Historically, the diagnosis of NMO required bilateral optic neuritis and transverse myelitis; however, the identification of a specific biomarker, NMO-IgG, an autoantibody against the aquaporin-4 (AQP4) water channel, has broadened NMO spectrum disease to include patients with diverse clinical and radiographic presentations. This chapter addresses the diagnosis, pathophysiology, and management of the disease.

Purpose To evaluate retinal nerve fiber layer thickness (RNFLT) using optical coherence tomography (OCT) in children with acquired demyelinating diseases. Methods This is a cross-sectional study of patients seen between 2006–2008 at the Pediatric MS Center of the Jacobs Neurological Institute. Consensus definitions for pediatric demyelinating disease were followed. All children received OCT testing and assessment of visual acuity (VA) using Snellen and low contrast letter acuity (LCLA) charts. Results Thirty-eight children diagnosed with acquired demyelinating disease, 15 healthy controls, and five children with other neurological disorders (OND) were included. Average RNFLT in healthy controls was 107 ± 12 μm( n = 30) versus 108 ± 5 μm ( n = 10) in OND controls. In children with multiple sclerosis, average RNFLT ± SD was 99 ± 14 μm in unaffected ( n = 24) versus 83 ± 12 μmin eyes affected by optic neuritis (“affected eyes”) ( n = 10). Average RNFLT in children with acute disseminated encephalomyelitis and transverse myelitis was 102 ± 15 μm in unaffected ( n = 18) versus 67 ± 17 μm in affected eyes ( n = 6). In children with optic neuritis (ON), average RNFLT ± SD was 97 ± 13 μm in unaffected ( n = 5) versus 89 ± 12 μm in affected eyes ( n = 9). Differences between children with demyelinating disease and controls and between ON and nonON eyes were statistically significant ( P < 0.001). Bivariate correlations of RNFLT with LCLA ( P = 0.002) and VA ( P < 0.001) were significant. Conclusions OCT may be a valuable tool for the assessment and monitoring of anterior optic pathway dysfunction in children with demyelinating diseases.

In this topical review, we discuss the history of the area postrema syndrome, with special attention given to early studies aimed at identifying the area postrema and its function, possible early cases of the syndrome and its current relevance in neuroimmunology and demyelinating diseases. In 1896, Retzius named a structure in the posterior medulla oblongata as the area postrema. The work of Borison in the middle of the 20th century led to the elucidation of its function as a “vomiting center.” The historical medical literature is filled with excellent examples that could be described as “area postrema syndrome.” While severe and bilateral optic neuritis and transverse myelitis still constitute the classic components of neuromyelitis optica spectrum disorder (NMOSD), intractable vomiting and hiccups due to area postrema involvement is now recognized as essentially pathognomonic, indeed a shiny pearl in neuroimmunology and demyelinating diseases.

We assessed chromatic discrimination in multiple sclerosis (MS) patients both with (ON) and without (no ON) a history of optic neuritis using the Cambridge color test (CCT). Our goal was to determine the magnitude and chromatic axes of any color vision losses in both patient groups, and to evaluate age-related changes in chromatic discrimination in both patient groups compared to normals. Using the CCT, we measured chromatic discrimination along the protan, deutan and tritan axes in 35 patients with MS (17 ON eyes) and 74 age matched controls. Color thresholds for both patient groups were significantly higher than controls' along the protan and tritan axes (p < 0.001). In addition, the ON and no-ON groups differed significantly along all three-color axes (p < 0.001). MS patients presented a progressive color discrimination impairment with age (along the deutan and tritan axes) that was almost two times faster than controls, even in the absence of ON. These findings suggest that demyelinating diseases reduce sensitivity to color vision in both red-green and blue-yellow axes, implying impairment in both parvocellular and koniocellular visual pathways. The CCT is a useful tool to help characterize vision losses in MS, and the relationship between these losses and degree of optic nerve involvement.
