Migraine
Conditions
Brief summary
This study aims to investigate whether the functional alterations in the brain of individuals with migraine appear before the peripheral vascular changes. This will be investigated using functional and structural neuroimaging in individuals with spontaneous menstually-related migraine.
Detailed description
Spontaneous migraine attacks are unpredictable and therefore been logistically arduous to investigate in neuroimaging studies. Menstrually-related migraine provides an opportunity to study spontaneous attacks in a controlled imaging setup. The present project aims to investigate women with menstrually-related migraine using daily functional magnetic resonance imaging (MRI) scans 2-3 days before the onset of the menstrual bleeding and until (and including) the headache phase of migraine or up to five consecutive days. A control-group of women without migraine will also be recruited and undergo the same MRI scan protocol.
