In this study the investigators will investigate the following hypothesis

  • that hypoxia induce migraine headache and migraine aura
  • the aura phase is associated with a spreading reduction in cerebral blood flow
  • the migraine headache is associated with dilatation of intra- and extracerebral arteries
  • the pre-ictal stage of a migraine attack with aura is associated with specific patterns in neural activity.

Primary Outcome Measures:
  • Headache and aura [ Time Frame: 24 h ] [ Designated as safety issue: No ]
    Comparison between hypoxia and placebo (atmospheric air)

Secondary Outcome Measures:
  • artery circumference [ Time Frame: Baseline, 90 and 180 min ] [ Designated as safety issue: No ]
    Hypoxia induced changes in intra- and extracranial circumference

  • Cerebral blood flow [ Time Frame: Baseline, 90 and 180 min ] [ Designated as safety issue: No ]
    Hypoxia induced changes in cerebral blood flow

  • Resting state functional connectivity [ Time Frame: Baseline and approximately 15 min post hypoxia ] [ Designated as safety issue: No ]
    To identify specific patterns in resting state functional connectivity (RSFC) in the pre-ictal stage of a migraine attack induced by hypoxia

Estimated Enrollment: 12
Study Start Date: April 2013
Estimated Study Completion Date: June 2015
Estimated Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Hypoxia
Inhalation of air with 8-12% oxygen content
Other: Hypoxia
Inhalation of hypoxic air (8-12% oxygen content)
Placebo Comparator: Atmospheric air
Inhalation of atmospheric air, with oxygen content at 21%
Other: Placebo
Inhalation of atmospheric air

Detailed Description:

To investigate migraine with aura symptoms during and after hypoxia.

With magnetic resonance imaging the investigators will investigate changes in

  • regional cerebral blood flow (rCBF)
  • resting state functional connectivity
  • circumference of the middle cerebral artery(MCA), internal carotic artery, superficial temporal artery, medial meningeal artery, external carotic artery
