What this trial is about
The investigators aim to define the neurofunctional phenotype of migraine patients who did not respond to at least 3 preventive treatments, including monoclonal antibodies (mAbs) targeting calcitonin gene-related peptide (CGRP) pathway (NON-responders). Primary aim will be to assess and compare changes in functional resting-state connectivity at baseline and after three months of mAbs treatment between patients who will achieve a reduction of monthly migraine days \>/= than 50% (namely Responders) and those who will not (namely Responders). The 2 groups will undergo a neurofunctional profile by means of High Density-electroencephalogram (HD-EEG) and functional-magnetic resonance imaging (fMRI).
Who can take part
Inclusion criteria
- male and female patients aged 18 to 75 years
- diagnosis of episodic migraine or chronic migraine according to ICHD-3 criteria
- for episodic migraine: 8-14 monthly migraine days in the previous 3 months
- diagnosis of resistant migraine, defined by having failed at least 3 classes of migraine preventatives and suffer from at least 8 debilitating monthly headache days for at least 3 consecutive months
- patients naive to CGRP targeting treatments
Exclusion criteria
- history of major psychiatric or other neurological conditions
- diagnosis of other primary or secondary headache disorders (only sporadic tension-type headache is allowed if the patients can clearly differentiate between the 2 types of headaches)
- changes in ongoing preventive treatment (if any) in the previous 3 months
- clinically significant medical conditions
- chronic pain conditions
- alcohol and/or drug abuse
