Miller Fisher syndrome with positivity of anti-GAD antibodies

Miller Fisher syndrome (MFS) is a variant of Guillain Barre yndrome (GBS) characterized by ophthalmoplegia, ataxia and areexia [1]. IgG antibodies against GQ1b are present inmore than 90% f acute MFS patients [2,3]. We report a case with typical clinical nd electrophysiological features of MFS with no anti-GQ1b antiodies in the blood serum and cerebrospinal fluid (CSF), but with ositivity of antibodies against glutamic acid decarboxylase (GAD) oth in serum and CSF.
