RT Journal Article SR Electronic T1 When the Guillain-Barré patient fails to respond to treatment JF Practical Neurology JO Pract Neurol FD BMJ Publishing Group Ltd SP 227 OP 230 DO 10.1136/jnnp.2009.176578 VO 9 IS 4 A1 Winer, J B YR 2009 UL http://pn.bmj.com/content/9/4/227.abstract AB Most patients with Guillain-Barré syndrome (GBS) respond to treatment with intravenous immunoglobulin, but it is not uncommon for some to continue to deteriorate for a period after treatment has been started. This may reflect the natural history of the disease, or an error in diagnosis. This article reflects my own view of what to do in this situation, with a review of what few data there are to guide decision making.
