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

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.

TL;DR: State-of-the-art MRI findings in patients presenting with a clinically isolated syndrome were discussed in a MAGNIMS workshop, the goal of which was to provide an evidence-based and expert-opinion consensus on diagnostic MRI criteria modifications.

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.

TL;DR: Patients with AQP4-IgG-positive NMOSD who received eculizumab had a significantly lower risk of relapse than those who received placebo, and there was no significant between-group difference in measures of disability progression.

TL;DR: The revised criteria facilitate the diagnosis of MS in patients with a variety of presentations, including “monosymptomatic” disease suggestive of MS, disease with a typical relapsing‐remitting course, and disease with insidious progression, without clear attacks and remissions.

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.

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.
