Study Description
Brief Summary:
To investigate headache score and accompanying symptoms during and after inhalation of carbon monoxide.

Condition or disease Intervention/treatment
Headache, Migraine Other: Carbon monoxide Other: AIR

Detailed Description:

To investigate headache score and accompanying symptoms during and after inhalation of carbon monoxide.

With transcranial Doppler imaging, c-scan and laser speckle the investigators will investigate changes in blood flow velocity of the middle cerebral artery (MCA), diameter of the superficial temporal artery (STA), the radial artery and facial skin perfusion.

Outcome Measures

Primary Outcome Measures :
  1. Headache scores, 12 hours [ Time Frame: 12 hours ]
    Comparison between carbon monoxide and placebo (atmospheric air)

Secondary Outcome Measures :
  1. Facial blood flow [ Time Frame: [ Time Frame: 0-180 min ] ]
    Carbon monoxide induced changes in facial blood flow before and after inhalation.
