[A method for prediction functional dizziness after benign paroxysmal positional vertigo]

Area of Science:

• Neurology
• Psychiatry
• Vestibular Disorders

Background:

• Benign paroxysmal positional vertigo (BPPV) is a common vestibular disorder.
• Functional vertigo (FV) can persist after BPPV treatment, impacting quality of life.

Purpose of the Study:

• To identify risk factors for functional vertigo (FV) in patients with benign paroxysmal positional vertigo (BPPV).
• To develop and validate a predictive method for FV development following BPPV treatment.

Main Methods:

• 93 BPPV patients (18-65 years) were assessed post-treatment.
• Evaluated history of panic attacks (PA), emotional, and personality disorders using standardized scales (DHI, VSS-SF, DDI, GAD-7, ASI).
• Developed a predictive model for FV using logistic regression.

Main Results:

• A history of panic attacks (PA) was significantly more frequent in patients who developed FV.
• Patients with FV reported higher scores on dizziness (DHI), vertigo symptoms (VSS-SF), depersonalization (DDI), anxiety (GAD-7), fear, and anxiety sensitivity (ASI).
• The predictive method demonstrated high sensitivity (78.9%) and specificity (94.12%) for diagnosing FV post-BPPV.

Conclusions:

• Emotional and personality factors, particularly PA history, are significant risk factors for developing FV after BPPV.
• The proposed predictive method can effectively identify individuals at risk for FV.
• Early screening using this method can aid in preventing persistent postural-perceptual dizziness.
