Brief Summary
This study aimed to investigate the role of the glymphatic system in the initiation of migraine attacks, using non-invasive magnetic resonance imaging techniques and a validated model of migraine induction by nitroglycerin administration. Secondarily, the relationship between the function of the glymphatic system during nitroglycerin-induced migraine attacks and sleep architecture and plasma levels of migraine-involved neuropeptides will be investigated.

Outcome Measures
Primary Outcomes (1)
Change from baseline glymphatic function after nitroglycerin administration
The DTI-ALPS index will be quantified before and after nitroglycerin administration as an indirect measure of the glymphatic function
Up to 8 hours
Secondary Outcomes (2)
Change from baseline plasma levels of neuropeptides after nitroglycerin administration
Up to 8 hours
Change from baseline sleep architecture after nitroglycerin administration
Up to 8 hours
Study Arms (2)
Adult patients with migraine
Diagnosis of migraine, by the ICHD-3 criteria. Age between 18 and 60 years. Female and males. Right-handed
Healthy controls
Age between 18 and 60 years. Female and males. Right-handed
Interventions
Sublingual nitroglycerin will be used to provoke spontaneous-like migraine attacks in migraine patients. A dose of 0.9 mg of sublingual nitroglycerin will be used. The same dose will be administrated to controls.
The following brain MRI sequences will be acquired before and after nitroglycerin administration: fluid attenuated inversion recovery (FLAIR), 3D T1-weighted inversion recovery prepared gradient echo, diffusion weighted sequence and 3D susceptibility weighted images.
Plasma levels of neuropeptides involed in migraine will be measured using commercially available enzyme-linked immune-sorbent assay (ELISA) kits. All ELISA will be performed by the same experienced technician who will be blinded for the clinical diagnosis.
Sleep architecture will be investigated using the Sleep Profiler. Sleep Profiler is medical device with CE mark which is produced by Advanced Brain Monitoring and distributed throughout Italy exclusively by Medigas. Sleep staging will be automatically performed for 30-second epochs throughout a dedicated software and a standardized and validated procedure. Frontopolar EEG signal waveforms will be visually inspected to confirm the accuracy of the auto-staging.
Eligibility Criteria
Patients with a diagnosis of episodic migraine without aura, by the standard ICHD diagnostic criteria, will be prospectively recruited. Patients will be allowed to take only one migraine preventive treatment at a stable dose during the study. Healthy controls suffering from any headaches with the exception of infrequent tension-type headache will be excluded from the study.
You may qualify if:
- For patients:
- Diagnosis of migraine, by the ICHD-3 criteria;
- For both patients and healthy controls:
- Age between 18 and 60 years;
- Willing and able to comply with scheduled visits.
You may not qualify if:
- For patients:
- Overuse of acute medications for headache;
- Continuous or daily headache;
- Other primary headache disorders, with the exception of infrequent tension-type headache.
- For healthy controls:
- Any subject with frequent tension type headache, migraine, cluster headache, other pain syndromes or neurological conditions.
- For both patients and healthy controls:
- Allergy to nitroglycerin;
- Major psychiatric disorders such as bipolar affective disorder and schizophrenia;
- Cardiovascular diseases that contraindicated the use of nitroglycerin;
- Intracranial hypertension;
- Cerebral haemorrhage;
- Cerebral trauma;
- Pulmonary toxic oedema;
- Closed angle glaucoma;
- +9 more criteria
