Abstract

Insights

Women with migraine showed increased deep white matter hyperintensities on MRI scans over 9 years. Migraine was not associated with other brain lesion progression in women or any lesions in men.

Area of Science:

  • Neurology
  • Neuroimaging
  • Epidemiology

Background:

  • Previous studies suggest a link between migraine and brain lesions.
  • Magnetic resonance imaging (MRI) has identified ischemic lesions in individuals with migraine.

Purpose of the Study:

  • To investigate the incidence of brain lesions in men and women with migraine over 9 years.
  • To determine if migraine frequency correlates with lesion progression.
  • To assess the association between brain lesion progression and cognitive decline.

Main Methods:

  • A prospective, population-based observational study followed a cohort of Dutch participants with migraine and a control group.
  • Participants underwent repeat MRI scans after 9 years to assess progression of deep white matter hyperintensities, infratentorial hyperintensities, and posterior circulation territory infarctlike lesions.
  • Cognitive function was also measured.

Main Results:

  • Women with migraine exhibited a higher incidence of deep white matter hyperintensities compared to controls (77% vs. 60%).
  • No significant association was found between migraine and the progression of infratentorial hyperintensities or posterior circulation infarctlike lesions in women.
  • Migraine was not associated with any MRI-measured brain lesion progression in men, nor was migraine frequency linked to lesion progression or cognitive decline.

Conclusions:

  • Women with migraine have an increased risk of developing deep white matter hyperintensities over time.
  • Migraine in men is not associated with the progression of MRI-detected brain lesions.
  • Further research is needed to understand the long-term neurological implications of migraine.
