Dizziness, migrainous vertigo and psychiatric disorders.

Area of Science:

• Neurology
• Psychiatry
• Otolaryngology

Background:

• Vestibular disorders are a common cause of dizziness.
• Psychiatric conditions like panic disorder and depression can manifest with dizziness.
• The link between psychiatric disorders, vestibular dysfunction, and migraine requires further investigation.

Purpose of the Study:

• To determine the prevalence of vestibular disorders, migraine, and definite migrainous vertigo in patients with psychiatric disorders presenting with dizziness.
• To explore the relationship between specific psychiatric diagnoses and vestibular abnormalities.
• To assess the impact of dizziness on quality of life using the Dizziness Handicap Inventory.

Main Methods:

• Retrospective analysis of out-patients at a university hospital.
• Otoneurological screening, including bithermal caloric stimulation, was performed on 102 patients.
• Patients were categorized into groups based on psychiatric diagnosis: panic disorder with agoraphobia, panic disorder without agoraphobia, and depressive disorders.

Main Results:

• Peripheral vestibular abnormalities were more prevalent in patients with panic disorder and agoraphobia, and in those with depressive disorders.
• Migraine was equally prevalent across groups, but migrainous vertigo was more common in panic disorder patients.
• Patients with peripheral vestibular disorders often received a diagnosis of definite migrainous vertigo and reported higher Dizziness Handicap Inventory scores.

Conclusions:

• Dizziness in patients with panic disorder, especially with agoraphobia, may be associated with vestibular system dysfunction.
• Migrainous vertigo appears to be a significant pathophysiological mechanism underlying vestibular disorders in this population.
• Further research is warranted to elucidate the complex interplay between psychiatric conditions and vestibular health.
