Dizziness: When Is It Migraine, and When Is It Not?

Area of Science:

• Neurology
• Otolaryngology
• Neuroscience

Background:

• Dizziness frequently co-occurs with headache, presenting diagnostic challenges due to overlapping symptoms with various vestibular disorders.
• Distinguishing vestibular migraine (VM) from other vestibular syndromes is crucial for appropriate patient management.

Purpose of the Study:

• To provide neurologists with guidance on differentiating dizziness attributed to vestibular migraine from other vestibular syndromes.
• To review current understanding of VM, including diagnostic criteria, pathophysiology, and treatment options.

Main Methods:

• Literature review of recent findings on vestibular migraine and related conditions.
• Analysis of diagnostic tools and clinical examination frameworks for VM.
• Comparison of VM with other vestibular disorders like BPPV, Meniere's disease, PPPD, and cerebrovascular events.

Main Results:

• Vestibular migraine is the leading cause of episodic vertigo, with evolving diagnostic criteria and insights into CGRP's role.
• Emerging diagnostic tools (VM-PATHI) and frameworks (TiTrATE) improve accuracy.
• Differentiating VM requires thorough clinical history, neurological exam, and understanding of its diverse presentations and comorbidities.

Conclusions:

• Accurate differentiation of VM from other vestibular causes of dizziness is essential for effective treatment selection.
• Further research is needed on biomarkers, subtypes, and comparative treatment trials for VM and its mimics.
