Dizziness is typically a benign and self-limited symptom, often diagnosed through a thorough patient history and physical exam. Further diagnostic testing is usually unnecessary for most dizziness cases.

Area of Science:

  • General Internal Medicine
  • Neurology
  • Otolaryngology

Background:

  • Dizziness is a common and often complex presenting symptom in primary care.
  • Understanding the etiology, prognosis, and diagnostic pathways is crucial for effective patient management.

Purpose of the Study:

  • To synthesize existing literature on the causes, outcomes, and diagnostic evaluation of dizziness.
  • To propose a practical primary care approach for evaluating dizziness.

Main Methods:

  • A structured literature synthesis was performed using MEDLINE and manual bibliography searches.
  • Data extraction was conducted independently by two investigators.

Main Results:

  • Peripheral vestibulopathies and psychiatric disorders are the most common causes of dizziness.

  • A careful history and physical examination yield a diagnosis in approximately 75% of cases.
  • Routine laboratory, cardiovascular, and neurologic testing have low diagnostic yield in unselected patients.

    • Conclusions:

    • Dizziness is generally a benign, self-limiting condition.
    • Clinical evaluation is paramount for diagnosing the cause of dizziness.
    • Specialized vestibular function testing requires further rigorous validation.
