Brief Summary
The main objective is to analyze the abnormality of physical condition, mental health and blood examination of the patients with benign paroxysmal positional vertigo (BPPV). Besides, the investigators aim to establish a database of BPPV based on multimodal magnetic resonance imaging data in the brain to identify high-risk patients with residual dizziness (RD) and systematically establish the comprehensive assessment system for the precise diagnosis, treatment and recovery of RD, optimize the tactics of BPPV management in China.

Outcome Measures
Primary Outcomes (8)
Differences between patients with BPPV and control group in brain structure
The changes of brain volume (mm3) are evaluated by structural MRI
baseline and 1 and 6 months
Differences between two groups in brain function
The changes of brain functional connectivity intensity are evaluated by functional MRI
baseline and 1 and 6 months
Changes on vertigo symptoms
Vertigo is assessed with the Dizziness Handicap Inventory (DHI Scale)
baseline and 1 and 6 months
Changes on vertigo symptoms
Vertigo is also assessed with the Activities-specific Balance Confidence Scale (ABC Scale)
baseline and 1 and 6 months
Changes on vertigo symptoms
Vertigo is also assessed with the Visual Vertigo Analogue Scale (VVAS)
baseline and 1 and 6 months
Difference in blood markers between the two groups
All subjects underwent fasting vein blood collection of about 5 ml at about 8 a.m. Blood indices related to BPPV and related clinical symptoms were screened, the inflammatory index is interleukin-6(IL-6)
baseline and 1 and 6 months
Difference in blood markers between the two groups
Immunology-related index in the blood sample is superoxide dismutase (SOD)
baseline and 1 and 6 months
Difference in blood markers between the two groups
Inflammatory index in the blood sample is neutrophils/lymphocytes
baseline and 1 and 6 months
Secondary Outcomes (8)
Differences in Fatigue between the two groups
baseline and 1 and 6 months
Differences in Sleep between the two groups
baseline and 1 and 6 months
Differences in cognition between the two groups
baseline and 1 and 6 months
Differences in executive function between the two groups
baseline and 1 and 6 months
Difference in anxiety between the two groups
baseline and 1 and 6 months
- +3 more secondary outcomes
Study Arms (2)
BPPV patients
Confirmed diagnosis of BPPV
Healthy controls
Healthy subjects who have not had BPPV
Interventions
Simultaneous cortico-spinal magnetic resonance imaging data were collected in a strong magnetic field and collected the serum of participants.
Eligibility Criteria
The study will be carried out in the First Affiliated Hospital Xi'an Jiaotong University for patients who had diagnosis of BPPV by the Dix-Hallpike maneuver or Supine Roll test. The healthy control population will be searched in the primary care services, media and social networks. All participants will sign informed consent.
You may qualify if:
- Confirmed diagnosis of BPPV/Healthy subjects who have not had BPPV
You may not qualify if:
- History of organic diseases in central nervous system and mental disorder, such as tumors, infections, depressive disorder, schizophrenia, etc. Claustrophobic
