Prevalence and impact of migrainous vertigo in mid-life women: a community-based study.

We surveyed 1436 women aged 40-54 years in the community. Of these, 278 (19.4%) were diagnosed with migraine or probable migraine based on the International Classification of Headache Disorder criteria. The diagnoses of migrainous vertigo (MV) were modified from Neuhauser's criteria. Of the 278 women, 238 (85.6%) underwent an interview and 72 (30.3%) of those with migraine or probable migraine had MV. The 1-year prevalence of MV among mid-life women was 5.0% (95% CI, 4.0-6.3%). The MV subjects had a higher proportion of aura (23.6% vs 9.6%; OR, 2.9), nausea (76.4% vs 55.8%; OR, 2.6) and photophobia (61.1% vs 41.7%; OR, 2.2) compared with the migraine subjects without MV. The migrainous subjects with and without MV had similar Short-Form 36 (SF-36) scores. Our study showed that MV was common in mid-life women. Their health-related quality of life was similar in migrainous subjects with MV and those without MV.
