Vestibular migraine

Area of Science:

• Neurology
• Otolaryngology

Background:

• Vestibular migraine (VM) is frequently misdiagnosed, often confused with brainstem aura.
• It is characterized by recurrent vestibular symptoms occurring in at least 50% of migraine attacks.
• The pathophysiology of VM is not well understood and is often extrapolated from general migraine mechanisms.

Purpose of the Study:

• To highlight the diagnostic challenges and clinical characteristics of Vestibular Migraine.
• To differentiate VM from other vestibular and neurological disorders.
• To underscore the need for further research into VM pathophysiology and treatment.

Main Methods:

• Diagnosis relies on clinical criteria from the International Classification of Headache Disorders (ICHD-3).
• Prevalence estimates suggest VM affects 1-2.7% of the adult population.
• Differential diagnoses considered include Ménière's disease, BPPV, and transient ischemic attack.

Main Results:

• Vestibular symptoms in VM can manifest before, during, after, or independently of headache.
• Symptom duration varies widely, from seconds to days.
• The exact timing of vestibular symptoms relative to headache is variable.

Conclusions:

• Vestibular migraine is an underdiagnosed entity requiring greater clinical recognition.
• Accurate diagnosis is crucial for appropriate management and to exclude other serious conditions.
• Specific treatment guidelines for VM are currently limited, indicating a need for further research and evidence-based recommendations.
