The developmental history of study on neuromyelitis optica

Abstract

In 19th century, neuromyelitis optica (NMO) indicated optic neuritis and myelitis with simultaneous onset of both sides. Later studies proposed that the onset of right or left side optic neuritis could be separated by weeks, months even years. The revolutionary discovery of aquaporin 4 (AQP4) antibody in 2004 by Vanda A Lennon challenged and changed the old concept of NMO. The concept of neuromyelitis optica spectrum disorders (NMOSDs) was proposed in 2007. Since then, a series of different terms have been proposed, including opticospinal multiple sclerosis (OSMS), NMOSDs, spectrum of NMO, expanded spectrum of NMO, etc. Through a summary of different concepts of NMO, this paper will make a comprehensive review on the evolution history of NMO study from 19th to 21st century, and the prospective targets of study will also be proposed.
