In this episode of the SRNA "Ask the Expert" podcast moderated by Dr. GG deFiebre, Dr. Kyle Blackburn and Dr. Benjamin Greenberg discussed the need for updated diagnostic criteria for myelitis. Dr. Blackburn explained the term myelitis and the importance of precise terminologies for accurate diagnoses and research [00:05:10]. Dr. Greenberg elaborated on the advancements in testing and understanding of associated disorders like NMOSD and MOGAD since 2002 [00:11:10]. Both experts stated that the shift from "transverse myelitis" to "myelitis" will aid future research, treatments, and patient care [00:17:27]. They reassured patients that these changes would essentially refine their care but not alter it dramatically [00:23:40]. They encouraged patients to stay informed and communicate with their healthcare providers about these updates [00:28:58].

![1309. Parenting is Hard | Part 5
At the end of this mini-series, we will host a Q&A episode where Barbara will answer questions from the community. To submit your question, please visit https://srna.ngo/submit
In part five of the “Ask the Expert, Research Edition” mini-series, “Parenting is Hard,” Krissy Dilger of SRNA was joined by Barbara Babcock to further explore her research concerning the changing beliefs around parenting when a child has been diagnosed with a rare neuroimmune disorder. They explored the theme of finding a balance in attending to the needs of all children in the family and discussed the importance of fairness and communication between parents [00:02:18]. The conversation also touched on the cultural differences and how these influence family dynamics and parenting strategies when one child requires more attention [00:13:33]. Barbara shared various strategies families use to ensure each child feels valued, such as integrating quality time into existing routines and understanding the different needs of children at various developmental stages [00:18:30].
Barbara Babcock works as a Family Therapist in a child and adolescent mental health outpatient unit in the United Kingdoms National Health Service. In her private practice, she works with individuals and couples who are navigating challenging health issues and wish to get their lives back. She obtained her Master of Science in Family Therapy from the Institute of Psychiatry, Psychology, and Neuroscience at Kings College London. Barbara also has a Master of Arts in Coaching Psychology/Psychological Coaching and her dissertation research focused on the impact that a systemic approach to coaching has on the wellbeing of adults who have a rare neuroimmune disorder and their primary caregivers. Previously, she was Chair of the Transverse Myelitis Society, from 2013 to 2016, and led their Family Weekend from 2015 to 2019, an event to support families who have a child/adolescent with a rare neuroimmune disorder to discover their potential through challenging outdoor activities. She had transverse myelitis in 2008 and is originally from Pennsylvania, USA. You can contact her at barbara@returntowellness.co.uk and her website is www.returntowellness.co.uk
