Summary

Longer follow-up in primary progressive multiple sclerosis (PPMS) reveals modest links between clinical decline and MRI changes. This 5-year study offers new insights into disease progression patterns in PPMS patients.

Area of Science:

  • Neuroimaging
  • Neurology
  • Clinical Research

Background:

  • Longitudinal imaging studies in PPMS show MR changes over 1-2 years.
  • Previous studies lacked evident correlation between MR measures and clinical change.
  • Insufficient observation periods may obscure these associations.

Purpose of the Study:

  • To investigate if longer observation periods reveal associations between clinical and MR measures in PPMS.
  • To assess changes in clinical and MRI parameters over 5 years in PPMS patients.

Main Methods:

  • Prospective 5-year follow-up of 41 PPMS patients.
  • Clinical assessments included EDSS and MSFC.
  • MRI assessments of brain and spinal cord were performed at baseline, 1, 2, and 5 years.

Main Results:

  • Significant deterioration observed in all clinical (EDSS, MSFC) and MRI measures by year 5.
  • Associations found between increased EDSS and decreased cord area.
  • Increased MSFC correlated with ventricular enlargement and T2 lesion load.

Conclusions:

  • A 5-year follow-up demonstrates modest associations between clinical and MR changes in PPMS.
  • MR measure rates of change were independent of age and disease duration.
  • Findings provide insights into individual PPMS progression patterns.
