NCT01896167

Brief Summary

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.
