About this study
Official title: Persistent Postural-perceptual Dizziness (PPPD): Prevalence and Diagnosis
Persistent Postural-Perceptual Dizziness (PPPD) is a chronic vestibular disorder characterized by persistent symptoms of dizziness or unsteadiness that lasts for three months or longer. It is one of the most frequent causes of chronic dizziness. Our study is designed to early recognize PPPD and to detect the most common precipitating factor of PPPD.
- Conditions
- Persistent Postural-perceptual Dizziness
- Being tested

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Comprehensive Audio-Vestibular EvaluationDiagnostic test
Every patient will undergo a detailed clinical history, Dizziness Handicap Inventory questionnaire, basic audiological evaluation, vestibular bedside tests, Computerized Dynamic Posturography including the sensory organization test, and a Video Head Impulse Test (vHIT).
| Study group | Role | What they receive |
|---|---|---|
| Persistent postural-perceptual dizziness patients | A cohort of 50 patients aged from 20 to 60 years diagnosed with Persistent postural-perceptual dizziness according to the Bárány Society diagnostic criteria. Patients undergo audio-vestibular evaluations to determine precipitating factors and clinical findings. Receives: Diagnostic Test: Comprehensive Audio-Vestibular Evaluation |
What is being measured
The primary outcome is the main question the study is designed to answer.
Prevalence of Persistent Postural-Perceptual Dizziness (PPPD) among patients with chronic dizziness
The proportion of patients with chronic dizziness who meet the diagnostic criteria for Persistent Postural-Perceptual Dizziness (PPPD) according to the Bárány Society criteria.
Measured: Baseline (At the time of clinical enrollment and audio-vestibular evaluation (single visit)).
