Most patients presenting with dizziness to a multidisciplinary clinic had peripheral vestibular disorders. Central causes were uncommon, and serious conditions like tumors were rare, though multiple disorders can coexist.

Area of Science:

  • Otolaryngology
  • Neurology
  • Vestibular Disorders

Background:

  • Dizziness is a common and often complex symptom.
  • Multidisciplinary clinics offer a comprehensive approach to diagnosis.

Purpose of the Study:

  • To evaluate the diagnostic yield and patient outcomes in a combined otolaryngology and neurology dizziness clinic.
  • To characterize the causes of dizziness in a tertiary referral setting.

Main Methods:

  • Prospective study of 812 consecutive patients over five years.
  • Involved thorough history, otoneurologic examination, and investigations.
  • Classified dizziness causes into peripheral, central, psychogenic, or undiagnosed categories.

Main Results:

  • Peripheral vestibular disorders accounted for the majority of dizziness (64.7%).
  • Central causes were less common (8.1%), with serious conditions being rare.
  • A significant percentage had undiagnosed (13.3%) or psychogenic (9.0%) dizziness.
  • Co-occurrence of peripheral and central causes was observed (4.9%).

Conclusions:

  • Peripheral vestibular disorders are the most frequent cause of dizziness in this specialized clinic.
  • Central nervous system causes of dizziness are relatively uncommon.
  • Patients may present with multiple contributing disorders, highlighting the complexity of dizziness.
