For this episode of our Ask the Expert podcast series, "The Future of Diagnosing Transverse Myelitis," Dr. GG deFiebre of SRNA was joined by Drs. Kyle Blackburn, Stacey Clardy, Eoin P. Flanagan, Benjamin Greenberg, Michael Levy, and Carlos Pardo-Villamizar. Dr. Carlos Pardo-Villamizar began by explaining the history of transverse myelitis. The experts then talked about criteria for TM published in 2002 and how the diagnostic process has changed in the past 20 years. They discussed the terminology of TM, how vascular causes of myelopathies change our understanding of diagnosing TM, and changes they foresee to the TM diagnostic criteria and process. Finally, they answered questions from the audience about potential research for treatments or a cure and COVID-19 vaccines.
