Objective

To assess the ictal symptoms, interictal symptoms, psychiatric comorbidities, and interictal neuro‐otologic examination findings in vestibular migraine (VM).

Methods

Retrospective chart review of 491 patients seen from August 2014 until March 2018 at a tertiary neurology referral center for vestibular disorders to identify patients fulfilling the 2012 VM criteria.

Results

One hundred and thirty‐one patients (105 women) were identified. Mean age of VM onset was 44.3 (±13.7) years. Preceding the onset of vestibular symptoms, most had migraine (57.3%) and motion sickness (61.1%). It was common to have a family history of migraine (50.8%) and episodic vestibular symptoms (28.1%). Common ictal symptoms were triggered (visually induced and head‐motion) and spontaneous vertigo, accompanied by photophobia and phonophobia (118/131 [90.1%] patients), nausea (105/131 [80.2%] patients), aural symptoms (79/131 [60.3%] patients), and headache (65/131 [49.6%] patients). Interictally, many experienced visually induced (116/131 [88.6%] patients), head‐motion (86/131 [65.6%] patients), and persistent (67/131 [51.1%] patients) dizziness. Psychiatric comorbidities include anxiety (92/131 [70.2%] patients), depression (53/131 [40.5%] patients), insomnia (38/131 [29.0%] patients), phobic disorders (15/131 [11.5%] patients), and psychogenic disorders (11/131 [8.4%] patients). Common triggers were stress (52/131 [39.7%] patients), bright lights (35/131 [26.7%] patients), weather changes (34/131 [26.0%] patients), and sleep deprivation (34/131 [26.0%] patients). Interictal neuro‐otologic examination was abnormal in 56/131 (42.7%), usually hyperventilation‐induced, head‐shaking‐induced, vibration‐induced, and positional nystagmus. The most common balance‐test finding was impaired sharpened Romberg’s test (22/130 [16.9%] patients).

Conclusions

In this single center study, we found that VM typically affects women in their 40s, with a personal and family history of migraine. Typical ictal symptoms were triggered and spontaneous vertigo, associated with photophobia and phonophobia, nausea, aural symptoms, and headache. Interictal vestibular symptoms, comorbid psychiatric disorders, and non‐specific interictal neuro‐otologic findings were common.
