Clinical presentation and prognosis in MOG-antibody disease: a UK study, Jurynczyk et al., identified that 55% of the cases had presented with optic neuritis, 24% were bilateral, 14% were longitudinal and extensive, 4% had short segment involvement, 9% had simultaneous optic neuritis and transverse myelitis, and 18% had ADEM (acute disseminated encephalomyelitis) or ADEM-like presentation [4]. 34% of MOGAD patients had brainstem or cerebellar involvement, and 63% were symptomatic. Here, MOG is linked to acute disseminated encephalomyelitis.
