The meeting, held between November 29 and December 2 in Barcelona, brought together experts and opinion leaders in the field of multiple sclerosis from around the world.
The McDonald criteria are the clinical criteria used to diagnose multiple sclerosis. Established in 2001, by an international panel of experts in the disease led by Ian McDonald, they have been modified in revisions in 2005, 2010 and 2017, with the aim of facilitating their use in clinical practice, shortening the time to diagnosis and initiation of treatment and improving case detection.
