OBJECTIVES:
To investigate the impact of the 2017 revisions of McDonald criteria on the diagnosis of multiple sclerosis (MS) in a cohort of patients with clinically isolated syndrome (CIS) and dissemination in space (DIS) of demyelinating lesions.
METHODS:
We retrospectively analyzed 137 patients with CIS + DIS from two Italian MS centers.
RESULTS:
Application of the 2017 revisions of McDonald criteria in our cohort led to a diagnosis of MS in 82.5% of the patients who could have not been diagnosed with MS according to the previous criteria at the time of the first demyelinating event. After a follow-up of 3.8 ± 2.9 years, 85.8% of these patients eventually satisfied also the previous (2010) criteria.
CONCLUSIONS:
Application of the 2017 revisions of McDonald criteria results in an earlier diagnosis of MS in a large percentage of CIS patients destined to convert to MS.
