Clinical otoneurological differences between vestibular migraine and probable vestibular migraine

Vestibular migraine (VM), and probable vestibular migraine (VPM), are frequent causes of vertigo. The objective of this study was to establish the prevalence of hearing loss and cochleovestibular paresis in patients with VM and PVM.

Otoneurological testing can distinguish vestibular migraine from probable vestibular migraine, and audiologists should be aware that hearing loss may be present in both groups, which has implications for differential diagnosis with conditions like Ménière's disease.

Clarifying the clinical boundaries between vestibular migraine and probable vestibular migraine supports more accurate diagnosis and may reduce misclassification with other vestibular disorders such as Ménière's disease.

1. 01Study identified measurable otoneurological (ear-and-balance nerve) differences between vestibular migraine and probable vestibular migraine.
2. 02Hearing loss prevalence was assessed in both diagnostic groups.
3. 03Probable vestibular migraine is a milder or less fully defined form not meeting all diagnostic criteria for vestibular migraine.
4. 04Findings have implications for differential diagnosis with Ménière's disease, which also features episodic vertigo and hearing loss.
