The 2024 Revisions of the McDonald Diagnostic Criteria for MS have been published in The Lancet Neurology. What do these changes mean for clinical practice?

In this episode, we are joined by two authors of the paper: Prof. Xavier Montalban, Chair of the International Advisory Committee on Clinical Trials in MS (IACCTMS), and Dr. Jiwon Oh of the University of Toronto. Together with host Brett Drummond of MStranslate, they discuss the significance of the updates, how these changes could expedite diagnosis and reduce misdiagnosis, and what they mean for the future of MS care globally.
