Abstract

Insights

This study compared multiple sclerosis (MS) patients with and without a family history. While clinical features were similar, MRI findings showed differences in plaque location, suggesting a role for genetic factors in MS.

Area of Science:

  • Neurology
  • Immunology
  • Genetics

Background:

  • Multiple sclerosis (MS) is a chronic, immune-mediated demyelinating disease with increasing prevalence in Iran.
  • Understanding the influence of genetic versus non-genetic factors is crucial for MS diagnosis and treatment.

Purpose of the Study:

  • To compare demographic, clinical, and MRI findings between MS patients with a family history (fMS) and sporadic MS patients (sMS).
  • To investigate the role of genetic and non-genetic factors in MS development and its clinical manifestations.

Main Methods:

  • A comparative study of 185 MS patients (62 fMS, 123 sMS).
  • Data collection included clinical examination, demographic information, disease course, medication, comorbidities, MRI findings, and EDSS scores.

Main Results:

  • Periventricular plaques were more frequent in sporadic MS patients (97.56% vs 88.71%, p=0.01).
  • Callosal plaques were more common in familial MS patients (62.9% vs 47.97%, p=0.05), a borderline significant finding.
  • No significant differences were found in demographic and clinical characteristics between fMS and sMS groups.

Conclusions:

  • Demographic and clinical features of familial MS and sporadic MS patients are comparable.
  • Significant differences in MRI findings between familial MS and sporadic MS patients highlight potential genetic influences on disease presentation.
