5 Key Takeaways

• 1

  A Swedish study found early-life infection and lifestyle factors affect benign multiple sclerosis (MS) likelihood 15 years post-onset.

• 2

  Patients with infectious mononucleosis, higher BMI at age 20, or low fish intake were less likely to have benign MS.

• 3

  Weekly fish consumption was associated with a milder disease trajectory in MS patients.

• 4

  Among 6,323 patients analyzed, 2,040 had benign MS, characterized by an EDSS score of 3 or lower after 15 years.

• 5

  The study highlighted the need for further research on biological mechanisms linking early exposures to MS outcomes.
