COVID-19 and Radiological Progression of Multiple Sclerosis: A Matched Cohort Study

This retrospective study compared brain MRI changes between 34 MS patients who tested positive for SARS-CoV-2 and 67 matched negative controls over approximately two years. No significant differences were found between groups in new lesions, enlarging lesions, gadolinium-enhancing lesions, or brain volume loss, suggesting COVID-19 does not accelerate radiological MS progression.
