This NMOSD and MOGAD meeting consisted of European and other international experts from the US, Japan, South Korea, Australia, Israel and China and a number of fellows who presented their latest research data. The main topics were 'MOGAD: the diagnostic criteria and implications and future', 'Biomarkers in individual patients: their pathological accuracy and clinical predictive value', 'Clinical trials: maximizing their value', and 'Comorbidities and other symptoms'. Lively debates around controversial areas were also included. The workshop agreed on key European projects to take forward and funding will also be used to cover a fellow to cover one of these projects.
