- Abstract
Objective: To determine if results from cervical vestibular evoked myogenic potential and ocular (oVEMP) testing can help differentiate Ménière's disease (MD) from vestibular migraine (VM). Method: Subjects: Age‐matched controls (n = 16), unilateral definite MD patients (n = 23), VM patients (n = 9) by Neuhauser's criteria. Intervention(s): Click and 500‐Hz tone‐evoked c‐ and oVEMPs. VM patients were further classified based on localization of symptoms. Outcome measure(s): CVEMP: corrected peak‐to‐peak amplitudes; oVEMP: n10 amplitudes. Results: Five VM patients were able to localize their symptoms to one ear. Relative to controls, MD and VM groups both showed reduced click‐evoked cVEMP (P <. 002) and oVEMP (P <. 026) amplitudes. Only the MD group showed reduction in tone‐evoked amplitudes for cVEMP (P =. 011). Tone‐evoked oVEMPs differentiated MD from VM patients (P =. 027), but only for VM patients who did not localize their symptoms to one ear (P =. 013). Conclusion: C‐ and oVEMP amplitudes are reduced in response to clicks in VM. 500‐Hz tone‐evoked oVEMPs may differentiate VM patients without localizing ear symptoms from MD, but those with localizing symptoms may have a similar pathophysiology to MD.
