Which comes first? Psychogenic dizziness versus otogenic anxiety

Area of Science:

• Otolaryngology
• Psychiatry
• Neurology

Background:

• Dizziness is a common symptom with multifactorial causes.
• The interplay between physical neurotologic conditions and psychiatric disorders in dizziness etiology is complex.
• Understanding these relationships is crucial for accurate diagnosis and treatment.

Purpose of the Study:

• To investigate the relationship between physical neurotologic conditions and anxiety disorders.
• To explore whether psychiatric disorders can cause dizziness.
• To identify risk factors associated with these dizziness syndromes.

Main Methods:

• Retrospective review of 132 patients treated for psychogenic dizziness.
• Comprehensive neurotologic and psychiatric evaluations were performed.
• Patients were grouped based on the primary cause of dizziness, and risk factors were compared.

Main Results:

• Three equally prevalent patterns of illness were identified: primary anxiety disorders causing dizziness (33%), neurotologic conditions exacerbating pre-existing psychiatric disorders (34%), and neurotologic conditions triggering new anxiety/depressive disorders (33%).
• Panic disorder and agoraphobia were more common in the first two groups, while less severe phobias were more prevalent in the third group.
• Risk factors for anxiety disorders were more common in patients with primary anxiety or exacerbation patterns.

Conclusions:

• Physical neurotologic conditions trigger psychopathology in dizziness as frequently as primary anxiety disorders cause dizziness.
• A significant pattern involves physical neurotologic conditions exacerbating pre-existing psychiatric illnesses.
• Individuals with risk factors for anxiety disorders may be more prone to primary psychopathology presenting as dizziness.
