前庭性偏頭痛與疑似前庭性偏頭痛之臨床耳神經學差異

// Clinical otoneurological differences between vestibular migraine and probable vestibular migraine

470名回顧研究：61%接受聽檢，檢測者40%有聽損（多為輕–中，51%單側）；VNG（眼震）異常88%、VHIT異常56%｜VM與PVM在聽損與前庭減弱盛行無差異，支持同一病理連續體；家族偏頭痛史為主要差異（64% vs 49%）。

// Retrospective cohort study of 470 adults with vestibular migraine (VM) or probable VM (PVM) (01/2024–12/2025) assessed demographics, audiometry, videonystagmography (VNG) and VHIT to determine prevalence of hearing loss and cochleovestibular paresis. Sixty-one percent underwent audiometry and 40% of those tested had hearing loss (mostly mild–moderate; 51% unilateral), 6.6% had documented cochleovestibular paresis, VNG was abnormal in 88% (commonly central positional nystagmus) and VHIT was abnormal in 56%. There were no significant differences between VM and PVM in prevalence or severity of hearing loss or cochleovestibular paresis. Findings support a single pathophysiological continuum for VM and PVM, with family history of migraine (64% VM vs 49% PVM) the main clinical differentiator.
