Comorbidities in vestibular migraine

Area of Science:

• Neurology
• Otolaryngology
• Neuroscience

Background:

• Growing evidence links vestibular symptoms and migraine.
• Current vestibular migraine (VM) diagnosis relies on symptom timing and lacks biomarkers.
• Consensus diagnostic criteria exist but require further refinement.

Purpose of the Study:

• To address the diagnostic challenges of vestibular migraine (VM).
• To focus on the impact of comorbidities in VM diagnosis and research.
• To explore the interaction between vestibular symptoms and migraine in the presence of other conditions.

Main Methods:

• Review of clinical and epidemiological evidence.
• Analysis of diagnostic criteria from Bárány Society and International Headache Society.
• Discussion of neurotologic and psychiatric comorbidities in VM.

Main Results:

• Diagnosis of VM is complicated by comorbidities like benign paroxysmal positional vertigo, Ménière's disease, and motion sickness.
• Migraineurs with VM often experience chronic subjective dizziness, potentially linked to temperament.
• Comorbidities create diagnostic uncertainty and may affect treatment response.

Conclusions:

• Understanding comorbidities is crucial for validating VM criteria and defining its boundaries.
• Further research with well-characterized patients is needed to elucidate the complex relationship between VM and other conditions.
• Comprehensive studies are required to fully understand the interaction of vestibular symptoms and migraine.
