13th Post-ECTRIMS Meeting: review of the new developments presented at the 2020 ECTRIMS Congress (II).

Introduction: For more than a decade, after the ECTRIMS Congress, Spain has hosted the Post-ECTRIMS meeting, where neurologists with expertise in multiple sclerosis (MS) meet to review the new developments presented at the ECTRIMS.
Aim: This article, published in two parts, summarises the presentations of the post-ECTRIMS meeting, held online on 16 and 17 October 2020.
Development: This second part highlights the importance of gender and age in understanding the pathology of the disease and optimising its management. The advances made in paediatric MS, from a neuropsychological and neuroimaging point of view, are presented. In turn, special attention is paid to the findings that contribute to a more personalised approach to therapy and to choosing the best treatment strategy (pharmacological and non-pharmacological) for each patient. Similarly, results related to possible strategies to promote remyelination are addressed. Although there are no major advances in the treatment of progressive forms, some quantitative methods for the classification of these patients are highlighted. In addition, the study also includes results on potential tools for assessment and treatment of cognitive deficits, and some relevant aspects observed in the spectrum of neuromyelitis optica disorders. Finally, the results of the papers considered as breaking news at the ECTRIMS-ACTRIMS are detailed.
Conclusions: Most of the advances presented were related to the knowledge of paediatric MS, remyelination strategies and cognitive assessment in MS.
