Clear Positive MOG Antibodies in Adults With Multiple Sclerosis Features: Diagnostic Challenges

Background and objectives: Distinguishing multiple sclerosis (MS) from myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) can be challenging because of some shared clinical and radiologic features. We aimed to describe adults with clear positive serum MOG antibodies (MOG-Abs) presenting with MS features and rethink their nosological framework.
