Migraine Attack Pain Phase Prediction Study

Patients with episodic migraine will be recruited from the monographic headache clinics of the 7 centers participating in the study. These patients, for a maximum period of 2 months, must monitor their hemodynamic variables with a wearable device and record all the clinical characteristics of their migraine attacks. Subsequently, with these records, an individualized algorithm will be created for each patient that aims to predict the onset of the migraine attack.

Inclusion criteria

• Age between 15 years and 69 years.
• Diagnosed with migraine by a headache neurologist and according to the criteria proposed by ICHD-3.
• History of migraine of at least 1 year of evolution.

• Have given your informed consent.
• Be able to describe your clinical situation and the characteristics of your headache.
• Have an average of 10 to 14 migraine days per month in the three months prior to inclusion (high-frequency episodic migraine).

Exclusion criteria

• Presence of another type of headache, with the exception of headache due to excessive use of analgesic medication.

• Neurological focus in the examination.
• Pregnancy or breastfeeding period.
• Patients with known heart disease or bronchopathy, Sjögren's syndrome, diabetes mellitus, or hypo/hyperthyroidism.
