Brief summary
Migraine with aura (MA) is an independent risk factor for stroke and is associated with silent brain infracts and T2 white matter hyperintensities on MRI. Previous studies using Transcranial Doppler (TCD) have shown an impairment of cerebral autoregulation in MA patients. Studies with positron emission tomography have demonstrated an activation of brain stem areas during migraine attack. An increased density of brain stem grey matter as measured on MRI with voxel based morphometry (VBM) has been found in MA patients. As brain arteries and arterioles are innervated by ascending tracts from aminergic brainstem nuclei, th study hypothesize a negative correlation between the density of brainstem nuclei and the efficiency of cerebral autoregulation in MA patients compared with controls. Brainstem grey matter density will be studied with a MRI Philips 3 Tesla with a 32-channel antenna and voxel-based morphometry (VBM) cerebral autoregulation will be measured in the time domain using Transcranial Doppler (TCD) and the Mx method. MA patients will be studied in a headache-free period. MRI and Transcranial Doppler (TCD) are non-invasive technics and will be performed on the same day.
Interventions
OTHERMagnetic resonance imaging
Patients and controls will first be studied with MRI. The total duration of MRI is about 60mn. These technic is not invasive.
OTHERTranscranial Doppler
Patients and controls will first be studied with TCD. The total duration of TCD is about 60mn. These technic is not invasive.
