The differences between migraineurs with vertigo or motion sickness or both, and migraineurs with neither might reflect differences in migraine pathophysiology. ⋯ Among the 871 definite migraineurs, 534 had MwV, 337 had MwoV, 663 had MwVS, and 208 had MwoVS. The MwVS group had more headache, aura, nausea, vomiting, osmophobia, allergy, allodynia, headache increasing with head motion, noise as trigger for headache, days needing analgesics, and higher migraine disability scores than the MwoVS group. The pattern was the same in the MwV vertigo group as in the MwVS group, apart from migraine disability scores, which were no different.

Clinical Trial
Vestibular functions were found to be impaired in patients with moderate-to-severe obstructive sleep apnea.
Obstructive sleep apnea (OSA) and balance disorders are common chronic diseases seen in the general population. The aim of this study was to evaluate vestibular functions in individuals with OSA. ⋯ 4

Clinical and electrographic findings in epileptic vertigo and dizziness: a systematic review.
Seizures can cause vestibular symptoms, even without obvious epileptic features. We sought to characterize epileptic vertigo or dizziness (EVD) to improve differentiation from nonepileptic causes, particularly when vestibular symptoms are the sole manifestation. ⋯ Non-isolated EVD is much more prevalent than isolated EVD, which appears to be rare. Diagnostic evaluations for EVD are often incomplete. EVD is primarily associated with temporal lobe seizures; whether this reflects greater epidemiologic prevalence of temporal lobe seizures or a tighter association with dizziness/vertigo presentations than with other brain regions remains unknown. Consistent with clinical wisdom, isolated EVD spells often last just seconds, although many patients experience longer spells.

Benign paroxysmal positional vertigo (BPPV) presentations are unique opportunities to simultaneously improve the effectiveness and efficiency of care. The test and treatment for BPPV--the Dix-Hallpike test (DHT) and the canalith repositioning maneuver (CRM), respectively--are supported by two evidence-based guidelines (American Academy of Otolaryngology--Head and Neck Surgery and American Academy of Neurology). ⋯ Despite this large effect size, less than 10% of affected patients receive the treatment, which shows that the management of BPPV in routine care is suboptimal. Future research is necessary to disseminate and implement the DHT and the CRM into routine practice.

Previous studies have shown that vertigo is the most powerful negative predictor of quality of life in patients with vestibular schwannomas, but the variability in vertigo symptom severity is still poorly understood. We wanted to find out whether vertigo could be related to objective parameters such as tumor size, location, vestibular nerve function, hearing, and postural stability in patients with untreated vestibular schwannomas. ⋯ A minority of VS patients experience severe vestibular symptoms related to canal paresis and postural instability. A curvilinear relationship is hypothesized between tumor size and dizziness.
