BACKGROUND: New diagnostic criteria of Multiple Sclerosis (MS) increase the number of patients being diagnosed with MS while a substantial part might not convert to clinically definite MS (CDMS). OBJECTIVE: Diagnostic accuracy of the McDonald 2005 and 2010 criteria for conversion to CDMS was evaluated in an unselected cohort of patients in whom a MS diagnostic workup was decided. METHODS: We analyzed clinical, MRI and CSF data in all patients who presented with symptoms suspicious for MS at the University based MS outpatient clinic between 2006 and 2010 (n=165). RESULTS: Follow-up was available for 131 patients. During the mean follow-up period of 2 years, 19% of patients developed clinically definite multiple sclerosis (CDMS) whereas 64% of the patients fulfilling McDonald2010 criteria did not convert to CDMS.Eur J Neurol. 2018 Feb;25(2):247-e9
