Purpose Of Review:
Misdiagnosis of multiple sclerosis (MS) is a prevalent worldwide problem. This review discusses how MS misdiagnosis has evolved over time and focuses on contemporary challenges and potential strategies for its prevention.
Recent Findings:
Recent studies report cohorts with a range of misdiagnosis between 5 and 18%. Common disorders are frequently misdiagnosed as MS. Overreliance on MRI findings and misapplication of MS diagnostic criteria are often associated with misdiagnosis. Emerging imaging biomarkers, including the central vein sign and paramagnetic rim lesions, may aid diagnostic accuracy when evaluating patients for suspected MS. MS misdiagnosis can have harmful consequences for patients and healthcare systems. Further research is needed to better understand its causes. Concerted and novel educational efforts to ensure accurate and widespread implementation of MS diagnostic criteria remain an unmet need. The incorporation of diagnostic biomarkers highly specific for MS in the future may prevent misdiagnosis.
Insights
Misdiagnosis of multiple sclerosis (MS) affects 5-18% of patients, often due to overreliance on MRI. New biomarkers and improved diagnostic criteria are crucial for preventing MS misdiagnosis and improving patient outcomes.
Area of Science:

Purpose of the Study:
- To review the historical evolution of multiple sclerosis misdiagnosis.
- To identify current challenges in diagnosing MS accurately.
- To explore strategies for preventing misdiagnosis.
Main Methods:
- Literature review of studies on multiple sclerosis misdiagnosis.
- Analysis of diagnostic criteria and imaging techniques.
- Discussion of emerging biomarkers and educational strategies.
Main Results:
- Recent studies indicate MS misdiagnosis rates ranging from 5% to 18%.
