A timely and accurate diagnosis of multiple sclerosis (MS) can considerably impact the lives of those affected, leading to prompt treatment and improved long-term outcomes. Recognizing this, experts have continually refined the McDonald diagnostic criteria, a set of guidelines used to diagnose MS, ensuring they remain aligned with the latest scientific understanding. Originally established in 2001[1] and last updated in 2017[2], these criteria aim to strike a balance between accurately identifying MS while minimizing false positives.
Since 2021, a dedicated panel of specialists has been diligently working to further refine the McDonald criteria, incorporating cutting-edge advancements in our understanding of MS’s biological mechanisms. This latest update prioritizes early and precise diagnoses by integrating refined imaging techniques and biomarker analysis alongside traditional clinical evaluations. This approach allows for more timely intervention and improved patient care.
The updated McDonald criteria were unveiled earlier this year at the 2024 european Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) Congress in Copenhagen, Denmark.Xavier Montalban, MD, PhD, chair of the committee, presented the revised criteria during a scientific session co-chaired by Peter Calabresi, MD.
Impact on Clinical Practice
Clinical insights from leading experts, shared during discussions with neurologylive®, offer valuable perspectives on how these updated criteria will transform MS diagnosis in everyday practice. These insights bridge the gap between cutting-edge research and real-world patient care. As part of HCPLive’s This Year in Medicine series, these clinical viewpoints expand the conversation beyond the guidelines themselves, highlighting thier practical implications for enhancing outcomes in MS management.
Proposed New Guidelines for Diagnosing MS
Proposed revisions to multiple sclerosis (MS) diagnostic criteria, presented at the 2024 ECTRIMS Congress, aim to enhance accuracy and consistency in diagnosis.These changes mark a shift in how MS is diagnosed and may lead to earlier detection in a wider range of patients. Xavier Montalban, chair of neurology at Hospital Universitari Vall d’Hebron and a leading figure in MS research, emphasizes the evidence-based nature of the new criteria. “During my presentation, I realized that while they may look quite complex, they are not so. Again, I want to highlight that the criteria are very much evidence based. I think this is the first time the entire set of criteria is truly evidence-based—they are sensible,logical,and the diagnostic algorithm is very easy to follow,” Montalban told *NeurologyLive* in a recent interview. Key changes include recognizing radiologically isolated syndrome (RIS) as MS in specific cases, adding the optic nerve as a fifth anatomical location for lesion assessment, and removing the requirement for dissemination in time (DIT). Updates to dissemination in space criteria were also introduced, along with the inclusion of kappa free light chains as a diagnostic tool.A Shift in Diagnostic Approach
The new criteria represent a significant departure from previous approaches, as they no longer necessitate a clinical syndrome, such as a relapse or progression, for diagnosis. This means MS could be diagnosed in patients with atypical symptoms or even no symptoms at all. “I view this as a significant shift in how we diagnose MS, primarily because we no longer require a clinical syndrome, such as a relapse or progression. So, we’ll be diagnosing MS in patients with atypical symptoms or even no symptoms,” Wallace Brownlee, MBChB, PhD, FRACP, consultant neurologist at Queen’s Square MS Center in London, told *NeurologyLive*. “It’s going to be an captivating time ahead.” These revisions also suggest the use of optional tools, such as the central vein sign (CVS) and paramagnetic rim lesions (PRLs), for specific cases, and recommend myelin oligodendrocyte glycoprotein antibody tests for diagnosing children and adolescents. Montalban emphasized the importance of using paraclinical evidence for confirming MS diagnoses across diverse patient populations. Clinicians believe these changes reflect a more nuanced approach to MS diagnosis, accommodating a broader spectrum of clinical presentations.
Updated MS Diagnostic Criteria Offer Hope for Earlier Diagnosis and Treatment
The landscape of multiple sclerosis (MS) diagnosis has been reshaped with the release of updated diagnostic criteria, promising earlier intervention for patients and potentially improving long-term outcomes.These revised guidelines, building upon the 2017 McDonald criteria, emphasize the integration of newer imaging techniques and biomarkers, providing a more complete and biologically-informed approach to identifying MS. One significant change in the new criteria is the formal recognition of the optic nerve as a “fifth topology” or classic location for MS lesions.While optic neuritis, inflammation of the optic nerve, has long been recognized as a common symptom of MS, it wasn’t explicitly included in the previous criteria. “I think adding that will be useful,” said Peter Calabresi, co-director of the Precision Medicine MS Center at Johns Hopkins University. He also highlighted the valuable role of advanced imaging technologies like optical coherence tomography (OCT), which can now detect subtle differences in the retinal nerve fiber layer between the eyes. An inter-eye difference of more than 6 microns in this layer or 4 microns in the ganglion cell inner plexiform complex can now contribute to a diagnosis of optic neuropathy, strengthening the case for MS. The inclusion of specific markers like cortical lesions visible on MRI (CVS) and paramagnetic rim lesions (PRLs) is another key advancement. Joseph Kuchling, MD, a postdoctoral research assistant at Charité University Berlin, explained that these additions could significantly improve the accuracy of diagnoses. “These additions could help improve the specificity of diagnoses,” Kuchling told *NeurologyLive*, noting that although the 2017 McDonald criteria were highly sensitive, they sometimes lacked specificity in real-world clinical settings.Early Diagnosis and Treatment: A Paradigm Shift
The updated guidelines hold immense promise for facilitating earlier diagnosis and treatment of MS. For patients presenting with strong indicators like CVS, the new criteria could lead to a quicker and more confident diagnosis, potentially avoiding the need to rule out other conditions such as sarcoidosis or neuromyelitis optica spectrum disorder. marcello Moccia,MD,PhD,assistant professor at the University of Naples,emphasized a essential shift in the understanding of MS reflected in the new criteria: “This shift is evident in two key aspects of the criteria,” he said. First, radiologically isolated syndrome (RIS), previously described as a set of MRI findings, can now be diagnosed as MS in specific cases where biological evidence of the disease is present. Second, the criteria for relapsing and progressive forms of MS have been unified, acknowledging the fluidity and complexity of the disease. While the new criteria offer hope for improved patient care, experts stress the importance of continued observation and evaluation in real-world clinical settings to fully understand their long-term impact. “It’s important to see how the new criteria perform in practice,” kuchling added.Revised McDonald Criteria: Advancing Multiple Sclerosis Diagnosis
The 2024 ECTRIMS meeting witnessed the unveiling of significant advancements in the diagnosis of multiple sclerosis (MS). experts presented the revised McDonald criteria, a refined system designed to improve the accuracy and efficiency of identifying MS. This evolution in diagnostic criteria marks a crucial step towards better patient care and understanding of the disease. Previously, separate criteria existed for different MS presentations. These revisions recognize the biological unity of MS, streamlining the diagnostic process. While the impact on immediate clinical practice may be modest, this change fundamentally advances our understanding and interpretation of the disease.Looking Ahead: Refining the diagnostic Landscape
The revised McDonald criteria, while a significant achievement, are not a final destination. Ongoing research and discussions at ECTRIMS 2024 highlighted several areas ripe for future exploration and refinement. Experts suggest that advanced techniques like visual evoked potentials (VEP) and optical coherence tomography (OCT) could provide more precise insights for demonstrating dissemination in time (DIT), a key element in MS diagnosis. Additionally, refining the use of pseudo-relapses (PRLs) and cerebrospinal fluid (CSF) analysis in specific contexts could further enhance diagnostic accuracy.
