Épidémiologie du vertige, de l'étourdissement et de l'instabilité, ainsi que leurs relations avec la migraine, le mal des transports, l'anxiété-dépression, le malaise vagal et l'agoraphobie

Abstract : Vertigo (V), dizziness (D) and unsteadiness (U) are common symptoms traditionally considered to result from different kinds of vestibular and non-vestibular dysfunctions. The prevalence of each symptom and how they relate to each other and to migraine, agoraphobia, motion sickness susceptibility (MSS), vaso-vagal episodes (VVE) and anxiety-depression (AD) was the object of this population-based study in north-eastern France. A self-administered questionnaire was returned by 2987 adults (age span 18-86 years, 1471 women). The 1-year prevalence for V was 48.3%, for U 39.1% and for D 35.6%. The VDU symptoms were correlated with each other, occurred mostly (69.4%) in various combinations rather than in isolation, less than once per month, and 90% of episodes lasted < or = 2 minutes and occurred < 1/month. The three symptoms were similar in terms of female predominance, temporary profile of the episodes and their link to falls and nausea. Symptom associations including I and symptom episodes of >1 hour increased the risk of falls. The number of drugs taken increased VDU even when controlling for age. Each VDU symptom was correlated with each co-morbidity. The risk factors were for agoraphobia: AD>female gender>VDU; for MSS: female gender>AD>migraine. Logistic regressions controlling for each vestibular symptom showed that V correlated with each co-morbidity, suggesting that V is a symptom as unspecific as the other two and that the three symptoms represent a spectrum resulting from a range of mechanisms or disorders
