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

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01896167
Recruitment Status : Completed
First Posted : July 11, 2013
Last Update Posted : February 12, 2015

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.

Condition or disease Intervention/treatment Phase
Headache Migraine Aura Other: Hypoxia Other: Placebo Not Applicable

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.

  2. Cerebral blood flow [ Time Frame: Baseline, 120 and 200 min ]
    Hypoxia induced changes in cerebral blood flow

  3. BOLD response in visual cortex [ Time Frame: Baseline, 170 min and 220 min ]
