Dizziness, often true vertigo, is common in emergency departments. History, physical exam, and the Hallpike test help diagnose peripheral vertigo, while neurological symptoms may indicate central causes requiring imaging.

Area of Science:

  • Neurology
  • Emergency Medicine
  • Otolaryngology

Context:

  • Dizziness is a frequent emergency department (ED) presentation.
  • True vertigo, a sensation of rotation, has peripheral (85%) and central (15%) origins.
  • Accurate diagnosis is crucial for appropriate management.

Purpose:

  • To outline the diagnostic approach to vertigo in the ED.
  • To differentiate between peripheral and central vertigo.
  • To emphasize the role of clinical evaluation and specific tests.

Summary:

  • Patient history and physical examination are key to identifying vertigo etiology in over 70% of cases.
  • The Hallpike test is essential for diagnosing benign paroxysmal peripheral vertigo (BPPV).
  • Central vertigo requires consideration and brain imaging in older patients, those with neurological symptoms, or cerebrovascular risk factors.

Impact:

  • Improved diagnostic accuracy for vertigo in the ED.
  • Timely identification of central vertigo, potentially indicating serious underlying conditions.
  • Guidance for clinicians on utilizing bedside tests effectively.
