Serum GFAP and Age Accurately Distinguish AQP4‐IgG Positive and Double Seronegative NMOSD From MOGAD After a Recent Attack

ABSTRACT Background Serum neurofilament‐light chain (sNfL) and glial fibrillary acidic protein (sGFAP) are associated with multiple sclerosis (MS) activity. This study aimed to identify patient‐ and disease‐level determinants of sNfL and sGFAP and to evaluate their ability to support differential diagnosis in neuromyel...

MRI Characteristics of Myelin Oligodendrocyte Glycoprotein Antibody-Associated Disease: A Review.

Importance Myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) is a demyelinating disease distinct from multiple sclerosis (MS) and aquaporin-4 antibody-positive neuromyelitis optica spectrum disorder (AQP4+NMOSD). Magnetic resonance imaging (MRI) is central to confirming attacks, defining lesion di...
