Summary

Multiple Sclerosis (MS) patients experience central white matter reduction, particularly in relapsing-remitting MS. Ventricular enlargement over six months suggests rapid atrophy, potentially linked to inflammation.

Area of Science:

  • Neuroscience
  • Radiology
  • Immunology

Background:

  • Axonal loss is a key factor in Multiple Sclerosis (MS) atrophy and fixed disability.
  • Estimating the rate of central white matter reduction is crucial for understanding MS progression.

Purpose of the Study:

  • To investigate the rate of central white matter reduction by analyzing ventricular volume changes.
  • To correlate ventricular volume changes with disease activity on MRI over a 6-month period in MS patients.

Main Methods:

  • Monthly MRI scans were performed on 19 patients over 6 months.
  • Ventricular volumes and lesion volumes were measured at baseline and serially.
  • Statistical analysis was used to assess changes and correlations.

Main Results:

  • Overall ventricular volume increased by 0.2% over the study period (P=0.02).
  • Relapsing-remitting MS showed significantly larger median ventricular volume increases (14.9%).
  • Ventricular volume changes did not correlate with serial changes in lesion volumes.

Conclusions:

  • Ventricular enlargement, indicating white matter loss, can occur rapidly in MS, especially in relapsing-remitting MS.
  • This rapid atrophy may be associated with preceding or ongoing inflammatory activity.
  • A combination of inflammatory and degenerative processes likely contributes to white matter loss in MS.
