Vestibular migraine: comparative analysis between diagnostic criteria

ABSTRACT INTRODUCTION: There is a strong association between vertigo and migraine. Vestibular migraine (VM) was described in 1999, and diagnostic criteria were proposed in 2001 and revised in 2012. OBJECTIVE: To compare the diagnostic criteria for VM proposed in 2001 with 2012 criteria with respect to their diagnostic power and therapeutic effect of VM prophylaxis. METHODS: Clinical chart review of patients attended to in a VM clinic. RESULTS: The 2012 criteria made the diagnosis more specific, restricting the diagnosis of VM to a smaller number of patients, such that 87.7% of patients met 2001 criteria and 77.8% met 2012 criteria. Prophylaxis for VM was effective both for patients diagnosed by either set of criteria and for those who did not meet any of the criteria. CONCLUSIONS: The 2012 diagnostic criteria for VM limited the diagnosis of the disease to a smaller number of patients, mainly because of the type, intensity, and duration of dizziness. Patients diagnosed with migraine and associated dizziness demonstrated improvement after prophylactic treatment of VM, even when they did not meet diagnostic criteria.

引言：眩晕与偏头痛之间存在密切关联。前庭性偏头痛（Vestibular Migraine, VM）于1999年被首次描述，2001年提出其诊断标准，并于2012年完成修订。
研究目的：对比2001年版与2012年版前庭性偏头痛诊断标准的诊断效能，以及二者在VM预防性治疗中的临床疗效。
研究方法：对前庭性偏头痛专科门诊就诊患者的临床病历开展回顾性分析。
研究结果：2012年版诊断标准使VM诊断更具特异性，将确诊患者范围收窄至更少群体：87.7%的患者符合2001年版诊断标准，而仅77.8%的患者符合2012年版标准。无论患者依据哪一版标准确诊，抑或未满足任一版诊断标准，VM预防性治疗均展现出良好疗效。
结论：2012年版VM诊断标准将疾病确诊范围收窄，这主要归因于眩晕的类型、强度及持续时间。即使是未满足诊断标准的偏头痛伴发眩晕患者，在接受VM预防性治疗后，症状仍可获得改善。
