Psychiatric symptoms in vertiginous patients

Area of Science:

• Neuroscience
• Psychiatry
• Otolaryngology

Background:

• Psychiatric comorbidity is frequently observed in patients experiencing vertigo.
• Individuals with a history of mental health conditions are at higher risk, but even previously healthy individuals can develop symptoms.
• Psychological factors play a crucial role in the morbidity associated with chronic vertigo.

Purpose of the Study:

• To determine the prevalence of psychiatric problems within a community sample of vertiginous patients.

Main Methods:

• Prospective evaluation of psychiatric symptoms using self-rating scales: Beck Depression Inventory (BDI), Zung Anxiety Scale (SAS), and DSM-IV and ICD-10 Personality Questionnaire (DIP-Q).
• Study conducted on 100 vertiginous subjects in a community sample at the Helsinki University Hospital's Academic Tertiary Otolaryngology Department.

Main Results:

• A high prevalence of psychiatric problems was found, with 68% of patients affected.
• Depressive symptoms were present in 19% and anxiety symptoms in 12% of patients.
• 63% of patients met the criteria for a personality disorder, most commonly obsessive-compulsive disorder (46%).
• Personality disorders were significant only when comorbid with anxiety and depression, not affecting functional capacity alone.
• No correlation was found between psychiatric symptom prevalence and vertigo severity or other comorbidities.

Conclusions:

• The study highlights a high prevalence of psychiatric symptoms in vertiginous patients.
• In chronic vertigo, subjective debilitation is not solely influenced by vertigo symptoms but significantly worsened by comorbid psychiatric disorders.
• Psychiatric differential diagnoses are essential in the neuro-otological evaluation of patients with chronic vertigo and significant disability.
