Banwell is a fellow of the American Academy of Neurology,[5] and serves as vice chair of the Academic Neurology Committee.[6] She has been active in the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS), delivering the 2022 ECTRIMS lecture.[7]
Banwell initially took her position at the University of Toronto intending to focus on neuromuscular disease in children. When she inherited five patients with multiple sclerosis from a retiring physician, she reports that her focus shifted to pediatric demyelinating disease.[11]
To better study a rare disease, Banwell created the Canadian Pediatric Demyelinating Disease Network in 2004, a multi-site network including all pediatric health-care facilities in Canada.[12] This has allowed Banwell and co-investigators to better understand diagnosis, treatment, and comorbidities of pediatric demyelinating disease.
Diagnosis: Banwell has been instrumented in evaluating the use of the McDonald criteria - standardized criteria to diagnose multiple sclerosis through determination of dissemination of central nervous system demyelination in space and time - in pediatric multiple sclerosis.[13] She has been the primary pediatric neurologist involved in international work to develop updates of the McDonald criteria for adults and children in 2010[14] and in 2017.[15]
Treatment: While many medications have become available for the treatment of multiple sclerosis over the last three decades, testing in children has been challenging due to the rarity of pediatric multiple sclerosis and ethical considerations with the use of placebo.[16] To facilitate and improve clinical trial design, Banwell created and currently chairs the International Pediatric Multiple Sclerosis Study Group. This allowed for the success of the PARADIGMS clinical trial, studying the safety and efficacy of fingolimod in a comparison with interferon beta-1a,[17] and led to approval of fingolimod by the Food and Drug Administration for pediatric multiple sclerosis, the first approval of a medication for this indication.[18]
Comorbidities: Banwell's work has shown that while children may recover physically from flares of multiple sclerosis, neuropsychological deficits may be apparent on testing, particularly in those who present at a younger age.[19][20] This knowledge has changed how families are counseled and supported through the diagnosis of multiple sclerosis.[21]
Acute Disseminated Encephalomyelitis, Neuromyelitis Optica and MOG Antibody Disease
Because demyelinating diseases in the pediatric population can be difficult to distinguish from each other, Banwell has worked to define and provide clinical guidelines for physicians working to delineate the diseases.[22]
In 2015, Banwell was on the International Panel for NMO Diagnosis (IPND) to develop international consensus diagnostic criteria for what became termed neuromyelitis optica spectrum disorder (NMO-SD).[23] She has also worked to determine the best treatment options for pediatric NMO-SD.
