Evaluation of Acute Dizziness and Vertigo

Area of Science:

• Neurology
• Otolaryngology
• Emergency Medicine

Background:

• Dizziness and vertigo are frequent reasons for emergency department visits.
• Accurate diagnosis is crucial for effective management of vestibular disorders.

Purpose of the Study:

• To provide evidence-based guidance for evaluating patients with acute dizziness and vertigo.
• To outline a systematic approach for classifying common causes of acute vestibular symptoms.

Main Methods:

• Utilizing a timing-and-triggers approach to characterize vestibular symptoms.
• Differentiating between continuous and episodic symptom patterns.
• Classifying symptoms based on triggers (spontaneous vs. post-exposure/triggered).

Main Results:

• Categorization into four key syndromes: post-exposure acute vestibular syndrome (AVS), spontaneous AVS, triggered episodic vestibular syndrome (EVS), and spontaneous EVS.
• A structured diagnostic framework for acute vestibular presentations.

Conclusions:

• A systematic, timing-and-triggers approach enhances the diagnostic accuracy of acute dizziness and vertigo.
• Classification into specific vestibular syndromes (AVS, EVS) guides appropriate clinical management.
