About this study

Official title: 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.
Read the 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • HypoxiaOther

    Inhalation of hypoxic air (8-12% oxygen content)

  • PlaceboOther

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Headache and aura

    Comparison between hypoxia and placebo (atmospheric air)

    Measured: 24 h

Secondary outcomes (4)
  1. artery circumference

    Hypoxia induced changes in intra- and extracranial circumference

    Measured: Baseline, 120 and 200 min

  2. Cerebral blood flow

    Hypoxia induced changes in cerebral blood flow

    Measured: Baseline, 120 and 200 min

  3. BOLD response in visual cortex

    Hypoxia induced changes in BOLD response

    Measured: Baseline, 170 min and 220 min

  4. Brain metabolism

    Hypoxia induced changes in brain metabolism

    Measured: Baseline, 180 min and 230 min post hypoxia

Questions about this trial

What is this clinical trial studying?

A study testing Hypoxia in people with Headache and Migraine, run by Danish Headache Center at 1 site in Denmark.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Feb 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Headache and aura (time frame: 24 h). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Feb 2015; AzTrials last refreshed its copy on 7 Nov 2026.
