Migraine With Aura Inducing Characteristics and Effects on the Cerebral Arteries and Blood Flow by Hypoxia

February 11, 2015 updated by: Nanna Arngrim, Danish Headache Center

Study of Migraine With Aura Inducing Characteristics and Effects on the Cerebral Arteries by Hypoxia in a Humane Experimental Migraine Model

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 migraine headache is associated with changes in brain metabolism
  • the pre-ictal stage of a migraine attack with aura is associated with specific patterns in neural activity.

Intervention / Treatment

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
  • brain metabolism

And compare these changes with a aged match healthy control group.
