Clinical clues to a dizzying headache.

Area of Science:

• Neurology
• Otolaryngology
• Neuroscience

Background:

• Migraine is increasingly recognized as a cause of vestibular symptoms.
• Despite growing interest, the concept of vestibular migraine (VM) lacks robust empirical data.
• Current understanding relies heavily on expert opinion rather than evidence-based research.

Purpose of the Study:

• To address the limitations in current research on vestibular migraine.
• To stimulate more rigorous clinical investigations into the relationship between migraine and vestibular symptoms.
• To explore key questions regarding patient selection, variable measurement, and clinical trial design for VM research.

Main Methods:

• Literature review and critical analysis of existing research on VM.
• Examination of applicable research methodologies, including epidemiology and genetics.
• Presentation of pilot data on pharmacologic and genetic dissection techniques.

Main Results:

• The research database for VM is surprisingly thin, with no consensus on its definition or essential features.
• Only one well-controlled medication trial for VM has been published, and no biomarkers are known.
• Current knowledge gaps hinder the development of empirically derived management guidelines.

Conclusions:

• There is an urgent need for rigorous clinical research to validate diagnostic criteria and establish evidence-based management for VM.
• Future research should focus on defining key variables, identifying appropriate patient cohorts, and designing trials that yield both clinical utility and pathophysiological insights.
• Developing practical, near-term research goals is essential for advancing the field of vestibular migraine.
