Abstract
Background:
Little is known about long-term cognitive and patient-reported outcomes of pediatric-onset multiple sclerosis (POMS).
Objective:
The objective of this paper is to compare cognitive and patient-reported outcomes in adults with POMS vs. adult-onset MS (AOMS).
Methods:
We compared standardized patient-reported measures MSQOL54, MFIS, CES-D and SDMT in adult patients with MS onset prior to and after age 18, using data gathered in the
Results:
Fifty-one POMS and 550 AOMS patients were compared. SDMT scores were significantly lower in POMS after adjusting for age (−7.57 (−11.72, −3.43; p < 0.001), but not after adjusting for disease duration. Estimated group difference demonstrated lower normative z scores in POMS vs. AOMS in unadjusted analysis (−0.74 (95% CI: −1.18, −0.30; p = 0.0009) and after adjusting for disease duration (−0.60; 95%CI: −1.05, −0.15; p = 0.0097). Findings were unchanged in a subset of POMS diagnosed prior to age 18. In unadjusted and adjusted analyses, no significant differences were observed in health-related quality-of-life, fatigue, depression or social support between POMS and AOMS.
Conclusions:
Younger age of onset was associated with more impairment in information-processing speed in adults with POMS compared to AOMS, and remained significant when controlling for disease duration in age-normed analysis. The two groups were similar in terms of patient-reported outcomes, suggesting similar qualitative experiences of MS.
