I just finished interviewing Divyanshu Dubey for the Neurology podcast. For today's Neurology Minute, I'm hoping you can tell us the main points of your paper. Dr. Divyanshu Dubey: Our paper talks about a rare form of autoimmune neuropathy associated with antibodies, CASPR1, as well as CASPR1/Contactin-1 complex IgG. These patients present with similar to CIDP, IDP, but tend to have more rapid progression, often a lot of sensory features preceding motor deficits including sensory ataxia in the contact and CASPR complex cases and presence of neuropathic pain in some of the
