China Dizziness and Vertigo Cohort Study （VERIDICAL STUDY）

Sponsor: Second Affiliated Hospital, Zhejiang University, School of Medicine

Summary

The goal of this observational study is to characterize the clinical features, etiological distribution, and longitudinal outcomes of patients with dizziness and/or vertigo in real-world neurological and otolaryngological outpatient settings across China. The main questions it aims to answer are: What is the etiological spectrum of dizziness and vertigo in patients presenting to neurology and otolaryngology clinics in China, and how do diagnoses evolve over time under routine clinical practice? Additionally, how do symptoms, functional impairment, and treatment responses change during follow-up? Participants presenting with dizziness and/or vertigo who are already receiving routine clinical care at participating hospitals will be enrolled in a multicenter registry. They will undergo baseline clinical assessment and complete standardized questionnaires, and will be followed at predefined intervals for up to 12 months (with possible extended follow-up) through outpatient visits, electronic diaries, or telephone interviews to assess diagnostic stability, symptom progression, and treatment outcomes in a real-world setting.
