Population-based study of vestibular symptoms in migraineurs

The differences between migraineurs with vertigo or motion sickness or both, and migraineurs with neither might reflect differences in migraine pathophysiology.

To assess vestibular symptoms in 871 definite migraineurs.

Data were gathered using a structured questionnaire. We considered responses to only 2/150 questions: (1) 'have you had vertigo with or apart from your headaches?' and (2) 'have you experienced motion sickness most of your life?'. The target groups were: (a) migraineurs with either vertigo or motion sickness, 'migraine with vestibular symptoms' (MwVS), their control group being migraineurs with neither vertigo nor motion sickness, 'migraine without vestibular symptoms' (MwoVS); (b) migraineurs who reported vertigo, 'migraine with vertigo' (MwV); their control group being migraineurs without vertigo (MwoV).

Among the 871 definite migraineurs, 534 had MwV, 337 had MwoV, 663 had MwVS, and 208 had MwoVS. The MwVS group had more headache, aura, nausea, vomiting, osmophobia, allergy, allodynia, headache increasing with head motion, noise as trigger for headache, days needing analgesics, and higher migraine disability scores than the MwoVS group. The pattern was the same in the MwV vertigo group as in the MwVS group, apart from migraine disability scores, which were no different.
