Table 4 Characteristics of Migraine Phases

From: My Migraine Voice survey: a global study of disease burden among individuals with migraine for whom preventive treatments have failed

  Premonitory Phase, % (N) Headache Phase, % (N) Postdromal Phase, % (N)
Duration of phase
  < 4 h 50% (5676) 20% (2280) 30% (3419)
 4–24 h 30% (3312) 45% (5067) 40% (4516)
  > 24 h 14% (1622) 34% (3835) 27% (3006)
 Not experiencing this phase 6% (656) 1% (84) 3% (325)
Proportion of individuals in each preventive treatment group reporting the duration of this migraine attack phase > 24 h:
  - No failure to migraine preventive treatment 11% (250) 27% (599) 20% (436)
  - 1 TF of migraine preventive treatment 11% (103) 29% (282) 23% (218)
  - ≥2 TFs of migraine preventive treatment 17% (1114) 38% (2539) 31% (2048)
  - P-value: ≥2 failures vs no failure of migraine preventative treatment < 0.05 < 0.05 < 0.05
Feeling very to extremely limited during the phase 29% (3047) 71% (8023) 30% (3291)
