Insights

Children with migraine with aura have a higher prevalence of patent foramen ovale (PFO). This finding suggests PFO may play a role in migraine with aura development in pediatric patients.

Area of Science:

  • Pediatric Neurology
  • Cardiology
  • Genetics

Background:

  • Patent foramen ovale (PFO) is a common cardiac anomaly.
  • The association between PFO and migraine, particularly in children, requires further investigation.
  • Migraine with aura presents unique diagnostic and therapeutic challenges in pediatric populations.

Purpose of the Study:

  • To investigate the prevalence of PFO in children diagnosed with migraine.
  • To compare PFO prevalence in children with migraine with aura versus those without aura.
  • To assess the potential link between PFO and the pathogenesis of pediatric migraine with aura.

Main Methods:

  • A cohort of 109 children (aged 6-18) with migraine underwent evaluation for PFO and right-to-left shunting.
  • Diagnostic tools included color-flow Doppler scanning, contrast transthoracic echocardiography, and contrast transcranial Doppler scanning.
  • Participants were categorized into migraine with aura and migraine without aura groups.

Main Results:

  • Overall PFO prevalence in children with migraine was 35%, similar to the general population.
  • PFO prevalence was significantly higher in children with migraine with aura (50%) compared to those without aura (27%).
  • No association was found between atrial shunt size and the presence or absence of aura.

Conclusions:

  • Children experiencing migraine with aura exhibit a notably higher prevalence of PFO.
  • These findings suggest that PFO may be a contributing factor in the development of migraine with aura in pediatric patients.
  • The study highlights the importance of considering PFO in the clinical evaluation and management of children with migraine with aura.
