ECTRIMS 2022 | Reappraisal of the 2017 McDonald criteria for multiple sclerosis

Jaume Sastre-Garriga, MD, PhD, Vall d’Hebron University Hospital, Barcelona, Spain, discusses possible changes to the 2017 McDonald criteria used to aid the diagnosis of multiple sclerosis (MS). Potential modifications feature the inclusion of optic nerve lesions as a fifth element for dissemination in space; whether optical coherence tomography (OCT) angiography or MRI should be used is still under discussion. Increasing the specificity of the MRI findings by describing the location and shape of the lesions and the inclusion of the central vein sign (CVS) and paramagnetic rim lesions (PRL) are also possible additions to the criteria. Additionally, radiologically isolated syndrome should be included in the diagnostic criteria of MS. This interview took place at the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) Congress 2022 in Amsterdam, The Netherlands.
