MOG-ab associated disease (MOGAD) is an autoimmune demyelinating syndrome associated with antibodies against MOG with a higher incidence in children, with variable phenotypes at presentation (ADEM, ON, TM, neuromyelitis Optica spectrum disorders (NMOSD) and/or encephalitis) but research is still full characterising this condition [8–10]. Here, MOG is linked to neuromyelitis optica.
