Demographic
 Participant count 24
 Sex (female/male) 21/ 3
 Age (mean ± SE, yrs) 31.33 ± 1.55
Clinical assessments
 Migraine duration (mean ± SE, yrs) 8.68 ± 1.47
 Migraine attacks (mean ± SE) 1.67 ± 0.25 (ranging from 1 to 5)
 VAS (mean ± SE) 38.60 ± 3.30

  1. Migraine attacks assessed attack times during the past 4 weeks. The VAS assessed the average migraine intensity of the 4 weeks preceding the first MRI scan. The MSQ, SDS, SAS were assessed preceding the first MRI scan
  2. VAS visual analog scale, MSQ Migraine Specific Quality of Life, SDS Self-rating Depression Scale, SAS Self-rating Anxiety Scale
