Cognitive impairment in early multiple sclerosis (MS) is linked to brain changes, not depression. Ventricular enlargement in MS patients correlated with cognitive decline, suggesting disease progression impacts brain function.

Area of Science:

  • Neurology
  • Neuroscience
  • Medical Imaging

Background:

  • Multiple sclerosis (MS) is a chronic neurological disease affecting cognitive function.
  • Early detection of cognitive changes in MS is crucial for management.
  • The relationship between subclinical brain changes and cognitive performance in early MS requires further investigation.

Purpose of the Study:

  • To investigate the hypothesis that cognitive function changes occur in early multiple sclerosis (MS).
  • To determine the relationship between ventricular enlargement and cognitive function in mild MS.
  • To differentiate the impact of disease progression versus depression on cognition in MS.

Main Methods:

  • Quantitative analysis of ten ventricular size measures in 123 MS patients and 60 healthy controls.

  • Comprehensive cognitive function assessment using sixteen tests.
  • Administration of the Beck Depression Inventory to assess mood.

    • Main Results:

    • Significant correlations were found between ventricular measures and cognitive performance in the MS group.
    • No significant correlations were observed between ventricular measures and cognitive performance in healthy controls.
    • Beck Depression Inventory scores did not correlate with cognitive performance or ventricular enlargement in MS patients.

    Conclusions:

    • Cognitive impairment in early MS is associated with the disease process, indicated by ventricular enlargement.
    • Ventricular enlargement serves as a potential biomarker for cognitive decline in MS.
    • Depression levels do not appear to be a primary driver of cognitive impairment in early MS.
