Only one child was seropositive for AQP4-IgG, and had a relapsing disease course with mild residual deficits. Of the remaining four children with AQP4-IgG negative NMOSD, three had a monophasic course and one had a relapsing course at latest follow-up. Two children with NMOSD were tested for anti-myelin oligodendrocyte glycoprotein (anti-MOG) antibody and both were seropositive. Conclusions: In this single centre Australian cohort of children with demyelinating CNS disorders, NMOSD represented 7[percnt] of all cases, and only one child was AQP4-IgG seropositive. These findings support those of previous studies, demonstrating that NMOSD is uncommon in children, and that AQP4-IgG seropositivity is rare in children presenting with CNS demyelination overall.
