    Science (New York, N.Y.)·2010

    Environmental factors like infection, stress, and trauma may influence Multiple Sclerosis (MS) relapses. This study tracked 50 MS patients, correlating documented events with clinical and MRI findings to understand disease activity triggers.

    Area of Science:

    • Neuroimmunology
    • Clinical Neurology

    Background:

    • Multiple Sclerosis (MS) is an autoimmune, demyelinating central nervous system disease.
    • Exacerbations in relapsing-remitting MS are often linked to environmental triggers.
    • Previous studies and legal cases suggest potential links between trauma and MS onset/worsening.

    Purpose of the Study:

    • To prospectively evaluate the impact of infection, emotional stress, and physical trauma on MS disease course.
    • To correlate documented environmental events with clinical and MRI-based disease activity.
    • To inform patient counseling regarding potential MS exacerbation triggers.

    Main Methods:

    • Prospective study of 50 relapsing-remitting MS patients in the Betaseron trial.
    • Participants maintained diaries documenting environmental events over two years.

  • Clinical evaluations and MRI scans were performed every six weeks.

    • Main Results:

    • Correlation analysis between documented events (infection, stress, trauma) and disease activity.
    • Assessment of impact on MRI-confirmed disease activity, relapse occurrence, and neurological progression.
    • Presentation of findings regarding the influence of specific environmental factors on MS.

    Conclusions:

    • The study provides data on the relationship between environmental events and MS activity.
    • Findings will guide patient counseling on managing potential triggers.
    • Understanding these triggers may lead to improved MS management strategies.
