MMN in Practice: A Rare Motor Neuropathy Often Misdiagnosed

Host: Jennifer Caudle, DO <br> Guest: Katie Beadon, MD, MASc, FRCPC <br> <p>Multifocal motor neuropathy (MMN) is a chronic, immune-mediated motor neuropathy that can mimic other neuromuscular disorders^1-3and is one of the few motor neuron disorders that is treatable.⁴ However, disease severity correlates with the length of time a patient remains untreated, which is why early recognition and treatment initiation is essential for preserving long-term motor function.^5-6 Joining Dr. Jennifer Caudle to discuss the diagnosis and management of MMN is Dr. Katie Beadon, Co-Director of St. Paul’s Hospital Immunotherapy in Neurology Clinic and an Assistant Clinical Professor at the University of British Columbia in Vancouver.</p> <p><strong>References:</strong></p> <ol> <li>Guimarães-Costa R, Bombelli F, Léger JM.
