Krissy Dilger of SRNA moderated an open Q&A on acute disseminated encephalomyelitis (ADEM) with pediatric neurologist Dr. Linda Nguyen of the University of Texas Southwestern Medical Center. Dr. Nguyen discussed how widespread MOG antibody testing has shifted many cases previously labeled ADEM to MOG antibody-associated disease, recommended MOG testing at onset, and reviewed relapse risk, mimics, and follow-up imaging [00:05:07]. Questions from the community covered acute treatments, recovery, guidance on pseudo-relapse, rehabilitation, and transition from pediatric to adult care [00:14:41].

Dr. Linda Nguyen completed her MD, PhD training at West Virginia University in 2017, and then pediatric neurology residency at the University of California, San Diego in 2022. She then completed a combined pediatric and adult neuroimmunology fellowship at the University of Texas Southwestern in 2024, where she now serves as an Assistant Professor in the Department of Pediatrics. Dr. Nguyen currently sees patients in the Demyelinating Disease Clinic at Children’s Medical Center Dallas.
