Outcome Measures
Primary Outcomes (1)
Frequency of each symptom as the first premonitory symptom
Premonitory symptoms will be recorded at the beginning of each migraine attack for a maximum of 5 migraine attacks per participant. For each premonitory symptom, the percentage of recorded attacks in which it was reported as the first symptom of the premonitory phase. Symptoms are recorded at headache onset for each attack via a structured electronic diary, capturing the type, sequence, onset, and duration of symptoms preceding the pain phase. The denominator is the number of recorded attacks with a premonitory phase.
Up to 6 months
Secondary Outcomes (7)
Time from onset of each premonitory symptom to headache onset (categorical intervals)
up to 6 months
Time from onset of each premonitory symptom to headache onset (minutes)
Up to 6 months
Intra-subject consistency of premonitory symptoms across attacks
Up to 6 months
Evolution and persistence of premonitory symptoms during the headache phase
Up to 6 months
Patient-level agreement between clinically reported and prospectively recorded presence of premonitory symptoms
Up to 6 months
- +2 more secondary outcomes
Other Outcomes (1)
Patterns of premonitory symptom transition and clustering
Up to 6 months
Study Arms (1)
patients with migraine
episodic migraine or chronic migraine or migraine with aura
