-Summary

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.

Arm	Type	Interventions	Description
Persistent postural-perceptual dizziness patients		Diagnostic Test: Comprehensive Audio-Vestibular Evaluation	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.

Comprehensive Audio-Vestibular Evaluation (Diagnostic 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).
