The "Community Meets Clinic" podcast series introduces clinicians and healthcare personnel specializing in rare neuroimmune disorders. In this episode, Krissy Dilger of SRNA spoke with Drs. Brenda Banwell and Haiwen Chen of Johns Hopkins Children’s Center, a designated Center of Excellence in Rare Neuroimmune Disorders. They shared about their paths into pediatric neurology and focus on rare pediatric neuroimmune disorders [00:01:49]. They described the rapid evolution of diagnosis and treatment over the past 30 years, including advances in MS, MOGAD, and aquaporin-4 disease, expanded pediatric inclusion in diagnostic criteria and trials, and improved outcomes with high-efficacy therapies. The doctors outlined their research approaches—Dr. Banwell’s integrative, imaging-focused team science [00:08:45] and Dr. Chen’s clinical research including a project on IVIG duration for relapsing pediatric MOGAD [00:11:00]. The discussed their multidisciplinary clinic supports, continuity into adulthood within one health system, and emphasis on availability, collaboration, community resources, and hope for the future [00:13:35].

In this SRNA “Ask the Expert” episode, Krissy Dilger of SRNA introduced the Rare Neuroimmune Disorder Symposium (RNDS), a three-day hybrid event in Dallas, Texas (October 15–17, 2026) that connects individuals and families with leading experts for education on diagnosis, symptom management, rehabilitation, mental health, and research. You can view details about RNDS, including the agenda and registration, on the event page:

https://www.srna.ngo/2026-rnds

SRNA founder and president Sandy Siegel recounted how early community isolation and a 1999 gathering helped spark ongoing symposia [00:08:37]. He described the development of a medical advisory board and collaboration with Johns Hopkins that supported research growth, evolving diagnostic definitions, and advances such as plasma exchange and newer therapies for conditions including TM, NMOSD, ON, ADEM, AFM, and MOGAD [00:12:11]. Community support coordinator Leah Campbell shared about her neuromyelitis optica (NMO) diagnosis and described RNDS as invaluable for expert access, treatment decision support, and meaningful connection with others who share similar experiences [00:34:45].

Sandy Siegel is the President of SRNA. Sandy got involved with SRNA shortly after his wife, Pauline, contracted TM in 1994 at the age of 35. At the time of her onset, Pauline was a kindergarten teacher. Sandy has been an officer and a board member of SRNA since its inception. Sandy has also served as SRNA’s newsletter and journal editor during his more than two decades of service to the organization. Sandy is a cultural anthropologist with specializations in Native Americans, psychological anthropology, and culture change. Sandy has worked as an adjunct professor at Capital University, Franklin University, the Urban/Rural Program of the College of Great Falls, and the Intertribal Education Center of the Fort Belknap Reservation. Sandy retired from the State of Ohio in 2011 after more than 35 years of service. Sandy returned to college in the fall of 2011 as a photography student at Columbus State Community College. Sandy and Pauline have two sons, four grandsons, and one granddaughter.

Leah Campbell is SRNA's Community Support Coordinator. Leah was diagnosed with neuromyelitis optica (NMO) in May 2006 after 17 years of unexplained symptoms and misdiagnosis. She was the first blind student and salutatorian of Altus High School and the first blind graduate of Rhodes College, earning a BA in mathematics. Following graduation and after a treatment for a disease she had been misdiagnosed with, she became quadriplegic and lost sensation of touch, having to relearn how to navigate life as both blind and paralyzed. She is dedicated to using her experiences to support and advocate for others.

In this SRNA “Ask the Expert” episode, GG deFiebre spoke with Dr. Michael Levy and Dr. Benjamin Greenberg about optic neuritis and how it is most often linked to multiple sclerosis but can also be idiopathic or associated with MOGAD and NMOSD. They compared differences across these conditions (including age patterns, bilateral involvement, severity, exam findings, and typical recovery), outlined diagnostic workups such as MRI, antibody testing, and spinal fluid studies, and reviewed acute treatments [03:14]. The discussion also covered emerging therapies like Pivikto for neuroprotection and efgartigimod alfa to lower IgG as a potential alternative to plasma exchange, and examined challenges in remyelination and stem-cell delivery approaches like Q-Cells while cautioning against unproven stem cell clinics [11:57].

In this "Community Spotlight Edition" of "Ask the Expert," Landy Thomas of SRNA spoke with Cindy Ranii about living with transverse myelitis (TM). Cindy described her diagnostic journey, rehabilitation, accessibility, and financial challenges [00:53]. She discussed returning to work briefly before retiring, emphasizing the importance of support, love, and community [08:51]. Cindy shared her path from wheelchair tennis to international wheelchair table tennis, and her pursuit of Paralympic qualification through point-based global competition [13:17]. She also discussed writing and self-publishing her book, Parakeet Races and Other Stories, inspired by family memories and her experience with TM [31:58].

Cindy Ranii is a 79-year-old retired educator who lives with her wife Shelly and service dog Hollis in Santa Cruz, California. In 2005, her life changed drastically when she was diagnosed with transverse myelitis (TM). Within four days, she went from golfing, playing tennis, and working vigorously as the Superintendent of a local high school district to being a paraplegic (T-3 complete).

Six months after her diagnosis she was back at work, using a wheelchair fulltime. Eighteen months later she decided to retire to have enough energy to enjoy her family (four children and 13 grandchildren) and to rebuild an active lifestyle. She competed in wheelchair tennis and then pursued table tennis with her eyes on the Paralympics. Currently she is training to compete in the 2028 LA Paralympics in wheelchair table tennis, saying, “My quest is to be the oldest Paralympian in history. It’s a long shot; but why not!”

Cindy has written numerous articles regarding living with a disability for New Mobility Magazine and authored a memoir, Parakeet Races and Other Stories, which is available through Amazon:

Dr. GG deFiebre of SRNA spoke with Dr. Michael Levy and Dr. Benjamin Greenberg about CAR-T therapy for aquaporin-4-positive NMOSD. They described why targeting B cells may reduce aquaporin-4 antibodies over time and could enable long-term remission or reduced need for ongoing drugs [01:37]. The physicians outlined an autologous Phase 1 study at Mass General and UT Southwestern [07:02]. They discussed eligibility rationale and how lessons from this NMOSD-focused trial could inform future neuroimmune disorder research [09:10]. You can find more information about the trial here:

Krissy Dilger of SRNA welcomed University of Washington neuroimmunologist Dr. Shuvro Roy for an open Q&A on transverse myelitis (TM). Dr. Roy explained how TM can be both a presentation and a diagnosis, with “idiopathic TM” used when extensive testing finds no underlying cause and noted that recurrence should prompt reevaluation for conditions like NMOSD, MOGAD, or neurosarcoidosis and consideration of preventive immunotherapy [00:06:16]. He addressed audience questions about lifestyle and rehabilitation topics including diet, metabolic health, exercise, sleep issues, and safe considerations around CBD or THC-containing gummies, and reviewed approaches to chronic pain, spasticity, physical therapy timelines, and spinal cord stimulation (including ArcX) [00:13:20]. Dr. Roy also discussed the current status of peptides and stem cells, highlighted emerging cell-based therapies like CAR-T, and answered a case question about a high MOG antibody titer and its diagnostic implications [00:24:53].

Shuvro Roy, MD is an Assistant Professor of Neurology at the University of Washington, specializing in neuroimmunology, with a specific focus on multiple sclerosis (MS) and related neuroimmunologic disorders.
