BMC Neurol. 2016 Jul 15;16(1):102. doi: 10.1186/s12883-016-0623-2.
BACKGROUND:This retrospective analysis explored prognostic factors associated with a benign multiple sclerosis (BMS) disease course at baseline and over the 4-year follow-up.
METHODS:Patients from the centralized New York State Multiple Sclerosis Consortium registry were classified as having BMS according to 3 different criteria centered on disease duration and disability. Additional analyses explored prognostic factors associated with BMS using the most conservative disability criteria (Expanded Disability Status Scale ≤2 and disease duration ≥10 years).
RESULTS:Among 6258 patients who fulfilled eligibility criteria, 19.8 % to 33.3 % were characterized as having BMS, at baseline depending on classification criteria used. Positive prognostic factors for BMS at baseline included female sex (p < 0.0001) and younger age at onset (p < 0.0001); negative prognostic factors included progressive-onset type of MS and African-American race. Of the 1237 BMS patients (per most conservative criteria), 742 were followed for a median of 4 years to explore effect of disease-modifying treatment (DMT) on benign status. DMT (p = 0.009) and longer disease duration (p = 0.007) were the only significant positive predictors of maintaining BMS at follow-up. The protective effect was stronger for patients taking DMT at both enrollment and follow-up (OR = 0.71; p = 0.006).
CONCLUSIONS:There is a need for development of more reliable prognostic indicators of BMS. Use of DMT was significantly associated with maintaining a benign disease state.

ProfG is not a fan of the term Benign MS as it is is only something that can be done retrospectively but if you do follow people who do not accumulate disability there are a number of factors associated with this. However, these only affect risk and nothing is absolute but if you are taking DMT you are less likely to worsen.

  1. Wow, I guess I had benign MS for 10 years! Now my spinal cord has thinned considerably and I visit this website way too often.
