About this trial
In this project, the aim is to recruit patients with drug resistant epilepsy and those suffering from migraine. Interestingly, patients suffering from epilepsy are also more often reporting to suffer from migraine. The pathobiology is understudied, but it is believed that both etiologies results from brain networks changes. A clinical certified 7T Terra Siemens scanner will be employed to assess in all participants (including healthy controls) how the microstructure differs in disease specific areas. Patients will further be clinically assessed as well as undergo questionnaires.
Migraine is also a common comorbidity to visual snow syndrom and has been shown to impact similar brain regions. However, the pathophysiology is still understudied and a better understanding of the two diseases is needed.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Patient must be able to read and sign the informed consent form
Stable prophylactic medication for 2 months prior to MRI
Patients diagnosed with migraine (with or without aura, episodic or chronic). Diagnosis is ensured by clinical interview (at least 8 weeks prior to MRI). Also, patients complete a migraine questionnaire (HARDSHIP) (at least 8 weeks before MRI). Migraine frequency ≥ 2 migraine attacks/month.
Patients with drug resistent epilepsy accroding to ILAE crtieria
Disqualifiers
Treatment of migraine disease with Botox within < 4 months before baseline and during the study period
Pregnant or breastfeeding women
Intention during the course of the trial to become pregnant
Women with bilateral ovariectomy, with or without hysterectomy, and postmenopausal women (>2 years of age) are not considered childbearing.
Trial population
The participants will be recruited from the primary care clinics as well as from referring physicians or other clinics. Healthy controls will be recruited via public announcements and via flyers distributed at a primary care clinic and two universities.

Treatments tested in this trial
Structural MRI
Diagnostic testWe will examine migraine and epilepsy patients as well as healthy controls using conventional structural MRI in the brain and spinal cord including T1-, T2-, and T2\*-weighted sequences
Quantitative MRI
Diagnostic testWe will examine migraine and epilepsy patients as well as healthy controls using quantitative MRI in the brain and spinal cord. This includes multi-parameter mapping (MPM) and quantitative susceptibility mapping (QSM).
Diffusion MRI
Diagnostic testWe will examine migraine and epilepsy patients as well as healthy controls using diffusion MRI in both brain and spinal cord.
fMRI
Diagnostic testWe will examine migraine and epilepsy patients as well as healthy controls using resting-state and task fMRI (including sensory stimulation using pain stimulus) in both brain and spinal cord.
MR Spectroscopy
Diagnostic testWe will examine migraine and epilepsy patients as well as healthy controls using MR Spectroscopy in both brain and spinal cord.
Treatment groups
Trial outcomes
Primary outcomes
MR: multi-parameter mapping (MPM)
MR: quantitative susceptibility mapping (QSM)
Resting-state fMRI (brain and brainstem/spinal cord)
MR: whole-brain structural scans
Secondary outcomes
Migraine patients: number of migraine attacks, intensity of migraine attacks (intensity 0 - 10), duration, accompanying symptoms, Migraine diary
Migraine patients: Headache-attributed restriction, disability, social handicap and impaired participation (HARDSHIP) questionnaire
Modified questionnaire including personal and socio-demographic, diagnostic questions related to migraine, and enquiry into headache-related burden without strict scale
Migraine/ epilepsy/ visual snow syndrome patients: recording of possible other headache disorders and medication overuse
HADS questionnaire (Hospital anxiety and depression scale)
0-42, higher score \> higher probability of anxiety/ depression
