Noninvasive vagus nerve stimulation provided rapid relief of vertigo and headache pain caused by acute vestibular migraine (VM), the most common neurologic cause of vertigo, according to a study using retrospective chart review. The study of 18 patients (Neurology 2019;93[18]: e1715-e1719), conducted at a single tertiary referral center between November 2017 and January 2019, found noninvasive vagus nerve stimulation (nVNS) reduced vertigo severity in 13 of 14 patients and offered “complete resolution” in two. Mean headache severity improved more than 63% according to the analysis, which included 16 women, but there was no improvement in interictal dizziness.
