Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In the study, the investigators would like to examine whether there is a difference between patients with vestibular migraine, patients with episodic or chronic migraine and healthy subjects in the examination of videonystagmography, which has been used for many years to differentiate and diagnose vertigo disorders. Accordingly, videonystagmography could also be discussed as an important diagnostic instrument for the diagnosis of the still young disease vestibular migraine.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Vestibular migraine is a young disorder that is caught between headache experts and vertigo experts. In 2012, the International Bárány Society for Neurootology and the International Headache Society were able to agree on a uniform definition and terminology for "vestibular migraine" in a jointly formulated consensus paper. A distinction is currently made between "definite" and "probable" vestibular migraine on the basis of the applicable diagnostic criteria. The diagnostic criteria are based on a study from 2001 with 75 patients and a follow-up period of 8 years, in which the diagnosis was confirmed in 84% of cases. At present the diagnostic criterion still requires the exclusion of another possible vestibular or ICHD diagnosis. Vestibular migraine is reported in the literature as the most common cause of spontaneous episodic vertigo attacks in adults and children. A manifestation is basically possible at any age. Despite the frequency of vestibular migraine and the sometimes pronounced level of suffering, the publication density is low and the diagnosis is mainly based on the patient medical history and clinical neurological examination. No specific instrumental diagnostic method or specific biomarkers that confirm or even prove the diagnosis are known. Larger studies with the intention of improving the diagnosis and thus achieving the expected reduction in the postulated high number of unreported cases have not yet been carried out. In the regular examination of patients with vertigo, videonystagmography with caloric testing is already an established and necessary examination procedure that is used to diagnose many different vertigo disorders. In the investigations, patients with confirmed vestibular migraine often show a vestibular hyperexcitability or increased caloric reaction not previously described in the literature. The investigators would like to verify this with this study. The investigators therefore developed the hypothesis of a possible correlation between a certain nystagmus frequency and/or certain speed of the slow phase of the nystagmus and the presence of a vestibular migraine. Comparisons with patients with headache migraine without accompanying vertigo symptoms and with a healthy control group should be carried out to test the hypothesis. First, all patients at the Dizziness Center at University Hospital Essen with diagnosed vestibular migraine without other conditions, except episodic or chronic migraine, were analyzed in the first quarter of 2023. This was followed by the inclusion of patients with episodic or chronic migraine and no vestibular migraine, standardized by age and gender, as well as the inclusion of a healthy control group without migraine headache and without vestibular migraine. Following that the collected data will be analyzed in particular the videonystagmography with caloric testing and the comparison of the groups.
