About this trial

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.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Confirmed diagnosis of BPPV/Healthy subjects who have not had BPPV

Disqualifiers

History of organic diseases in central nervous system and mental disorder, such as tumors, infections, depressive disorder, schizophrenia, etc. Claustrophobic

Trial population

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.

Trial outcomes

Primary outcomes

1

Differences between patients with BPPV and control group in brain structure

The changes of brain volume (mm3) are evaluated by structural MRI

Time frame
baseline and 1 and 6 months
2

Differences between two groups in brain function

The changes of brain functional connectivity intensity are evaluated by functional MRI

Time frame
baseline and 1 and 6 months
3

Changes on vertigo symptoms

Vertigo is assessed with the Dizziness Handicap Inventory (DHI Scale)

Time frame
baseline and 1 and 6 months
4

Changes on vertigo symptoms

Vertigo is also assessed with the Activities-specific Balance Confidence Scale (ABC Scale)

Time frame
baseline and 1 and 6 months

Secondary outcomes

1

Differences in Fatigue between the two groups

Fatigue is assessed with the Multidimensional Fatigue Inventory (MFI). A higher score represents a worse outcome. The MFI is a 20-item self-report instrument covering four dimensions (general fatigue, physical fatigue, mental fatigue, reduced motivation and reduced activity) designed to measure fatigue.

Time frame
baseline and 1 and 6 months
2

Differences in Sleep between the two groups

Sleep quality is assessed with Pittsburgh Sleep Quality Index (PSQI). A higher score corresponding to a worse sleep quality.

Time frame
baseline and 1 and 6 months
3

Differences in cognition between the two groups

The cognition is assessed with Montreal Cognitive Assessment (MoCA). Higher scores (0-30) are related to a better performance.

Time frame
baseline and 1 and 6 months
4

Differences in executive function between the two groups

The executive function is assessed with Trail Making Test A and B. Participants are asked to connect sequential numbers (TMT-A) and interconnect sequential numbers and letters (TMT-B).

Time frame
baseline and 1 and 6 months
