International Clinical Protocol on Vestibular Disorders (Dizziness)

Area of Science:

• Neurootology
• Equilibriometry
• Vestibular System Science

Background:

• Dizziness (vestibular disorders) has a high prevalence (22.9%) and incidence (3.1%), with low physician consultation rates (1.8%).
• Existing evidence for dizziness evaluation is weak, highlighting the need for an evidence-based consensus document.
• The 43rd Congress of the Neurootological and Equilibriometric Society focused on establishing an International Clinical Protocol for Vestibular Disorders.

Purpose of the Study:

• To present a new International Clinical Protocol for Vestibular Disorders (Dizziness) accepted as a Consensus Document.
• To outline a novel conceptual framework for the vestibular system, integrating peripheral sensors, central processing, and motor outputs.
• To establish evidence-based guidelines for the evaluation and management of dizziness.

Main Methods:

• Development of a new concept of the vestibular system, encompassing peripheral sensors (detecting acceleration, gravitation, vibration, infrasound, magnetic impulse, metabolic changes), central integration in the brainstem, cortical representation, and efferent pathways.
• Integration of inputs from visual, acoustic, and somatosensory organs within the vestibular system for space perception and orientation.
• Utilizing diagnostic tools such as Vestibular Evoked Potentials (not VEMP) and craniocorpography, noted for high sensitivity (>90%).

Main Results:

• The protocol defines the vestibular system's complex architecture, including six sensory modalities and integration with other sensory organs.
• Vestibular dysfunction can manifest through various symptoms, including visual disturbances (paropsia), tinnitus, and numbness.
• Vestibular Evoked Potentials and craniocorpography demonstrate high diagnostic sensitivity for vestibular dysfunction.

Conclusions:

• A new consensus document and clinical protocol for vestibular disorders have been established.
• The updated understanding of the vestibular system provides a framework for more accurate diagnosis and management.
• Recurrent vestibular dysfunction necessitates ongoing patient monitoring, supported by sensitive diagnostic tools.
