Abstract
Editors' Note: The international consensus diagnostic criteria for neuromyelitis optica spectrum disorders (NMOSD) article prompted reactions from our readers. Tan is concerned that the new criteria may include patients without true neuromyelitis optica and may affect treatment funding. Recounting their own experience, Mao et al. caution about overinterpretation of MRI results and suggest that aquaporin-4 antibody (AQP4-Ab) testing be considered in late-onset demyelinating disease. In response, Wingerchuk et al., authors of the guidelines, stress that the diagnostic category of NMOSD without AQP4–immunoglobulin G requires exclusion of alternative diagnoses, believe that the new criteria will facilitate—rather than hinder—insurance coverage for appropriate immunosuppressive treatments, and agree with the observations raised by Mao et al. —Chafic Karam, MD, and Robert C. Griggs, MD Wingerchuk et al.1 proposed criteria for neuromyelitis optica (NMO) spectrum disorders (NMOSD) that incorporated unifying the terms NMO and NMOSD, including patients with aquaporin-4 (AQP4)–immunoglobulin G (IgG) negative/unknown, thus giving these patients …

Diagnosis of multiple sclerosis: 2017 revisions of the McDonald criteria

TL;DR: The 2017 McDonald criteria continue to apply primarily to patients experiencing a typical clinically isolated syndrome, define what is needed to fulfil dissemination in time and space of lesions in the CNS, and stress the need for no better explanation for the presentation.

Clinical presentation and prognosis in MOG-antibody disease: a UK study.

TL;DR: MOG-antibody disease has a moderate relapse risk, which might be mitigated by medium term immunosuppression at onset, and permanent disability occurs in about half of patients and more often involves sphincter and erectile functions than vision or mobility.

A serum autoantibody marker of neuromyelitis optica : distinction from multiple sclerosis

TL;DR: NMO-IgG is a specific marker autoantibody of neuromyelitis optica and binds at or near the blood-brain barrier that distinguishes neuromyleitis opticas from multiple sclerosis.

IgG marker of optic-spinal multiple sclerosis binds to the aquaporin-4 water channel.

TL;DR: It is shown that NMO-IgG binds selectively to the aquaporin-4 water channel, a component of the dystroglycan protein complex located in astrocytic foot processes at the blood-brain barrier, which may represent the first example of a novel class of autoimmune channelopathy.

The spectrum of neuromyelitis optica

TL;DR: Data suggest that autoantibodies to aquaporin 4 derived from peripheral B cells cause the activation of complement, inflammatory demyelination, and necrosis that is seen in neuromyelitis optica.
