Study of Clinical Features and Brain Imaging in Adults Aged 18 to 60 with Benign Paroxysmal Positional Vertigo BPPV and Healthy Volunteers in China

What this Trial Is About

Researchers are conducting an observational study to analyze physical condition abnormalities, mental health, and blood test results in patients with benign paroxysmal positional vertigo BPPV. The study also aims to create a brain MRI database to identify patients at high risk of residual dizziness and develop a comprehensive system for diagnosing, treating, and recovering from residual dizziness in China. Participants include confirmed BPPV patients and healthy individuals without BPPV. Both groups will undergo behavioral and psychological assessments, blood sample collection, and three brain MRI scansat the start of the study, and again one month and six months after treatment for BPPV patients. Healthy controls complete these assessments only once at inclusion. During the study, participants will fill out psychological questionnaires, provide blood samples at a local lab, and receive brain MRI scans. Researchers will monitor differences in brain structure and function, vertigo symptoms, and blood markers over time. Additional assessments include fatigue, sleep, cognition, executive function, anxiety, depression, verbal memory, working memory, and auditory attention. The study will run until September 2026.
