ABSTRACT: Ménière's disease (MD) is characterized by episodic vertigo, fluctuating hearing loss and tinnitus. Vestibular migraine (VM) is a relatively new disorder that is characterized by episodic vertigo or dizziness, coexisting migraine and absence of hearing loss. It is occasionally difficult to distinguish between VM and vestibular MD with headache. Because endolymphatic hydrops (EH) is a characteristic sign of MD, we attempted to evaluate endolymphatic space size in both diseases. Endolymphatic space size in the vestibule and the cochlea was evaluated in seven patients with VM and in seven age- and sex-matched patients with vestibular MD. For visualization of the endolymphatic space, 3T magnetic resonance imaging was taken 4 h after intravenous injection of gadolinium contrast agents using three-dimensional fluid-attenuated inversion recovery and HYbriD of reversed image of positive endolymph signal and native image of positive perilymph signal techniques. In the vestibule of VM patients, EH was not observed, with the exception of two patients with unilateral or bilateral EH. In contrast, in the vestibule of patients with vestibular MD, all patients had significant EH, bilaterally or unilaterally. These results indicate that endolymphatic space size is significantly different between patients with VM and vestibular MD.Journal of Neurology 08/2014; 261(11).

ABSTRACT: Vertigo patients exhibiting features of vestibular migraine (VM) and Menière's disease (MD) present a difficult diagnostic challenge to the clinician, and the two entities are likely to overlap. The aim of the present study was to investigate the occurrence of endolymphatic hydrops in patients with VM and auditory symptoms. This was an observatory diagnostic study. At an academic interdisciplinary dizziness centre, nineteen consecutive patients with definite or probable VM and auditory symptoms were examined by locally enhanced inner ear MR imaging. MR images were evaluated for the presence of endolymphatic hydrops. Of the 19 included patients, four patients (21 %) demonstrated evidence of cochlear and vestibular endolymphatic hydrops on locally enhanced inner ear MR imaging (three with "definite VM", one with "probable VM"). Locally enhanced inner ear MR imaging may be useful in the diagnostic evaluation of patients with VM and auditory symptoms, as some of these patients have signs of endolymphatic hydrops. Whether these patients suffer from MD only and are misdiagnosed as VM or suffer from both, VM and MD or whether endolymphatic hydrops is a consequence of inner ear damage due to VM are clinically relevant questions that can be evaluated by application of this technique.Archives of Oto-Rhino-Laryngology 10/2013; 271(10).

ABSTRACT: Awareness of the importance of migraine in patients with symptoms of vestibular dysfunction is increasing. This article gives an overview of the multiple facets of the link between migraine and vestibular dysfunction. The vestibular and the headache community have published a consensual definition of vestibular migraine, which is an important step to promote research on the topic and the awareness of clinicians. Vestibular migraine is considered the most common cause of spontaneous recurrent vertigo. So far, the evidence for vestibular migraine has been mainly epidemiological, but the recent follow-up of a cohort over 9 years could show the robustness of the diagnosis over time.Additionally, migraine and vestibular dysfunction have multiple potential interactions and links through a range of comorbidities such as Menière's disease, benign paroxysmal positional vertigo, anxiety and motion sickness, which go beyond the diagnostic entity of vestibular migraine. The further refinement and wider acceptance of the diagnostic entity of vestibular migraine is an important development as it is one the most common vestibular disorders. But the relationship between migraine and vestibular dysfunction is complex and has many aspects beyond vestibular migraine.Current opinion in neurology 12/2013; DOI:10.1097/WCO.0000000000000061 · 5.73 Impact Factor
