What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study is looking at whether people with benign paroxysmal positional vertigo (BPPV) have differences in their autonomic nervous system compared to healthy people. Researchers will measure heart rate variability (HRV) in 104 participants (52 with BPPV and 52 matched controls) during rest and controlled breathing. They will also assess perceived stress levels to see if stress is linked to autonomic function in BPPV. The goal is to better understand the biological connection between vertigo and stress.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If this study finds a clear link between BPPV and autonomic dysfunction, it could point toward stress management or vagal tone therapies as supportive treatments for vertigo.
What could go wrong
This is a small, early observational study, not a treatment trial. It may find no meaningful differences between groups, and any associations may not lead to new therapies.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population will consist of adult patients presenting to the otolaryngology outpatient clinic of Istanbul Aydın University Hospital with complaints of vertigo and diagnosed with benign paroxysmal positional vertigo (BPPV) based on clinical evaluation and positional testing (Dix-Hallpike and/or Roll test). The control group will include age- and sex-matched healthy volunteers without a history of vertigo or vestibular disorders. All participants will be recruited from individuals attending the same hospital during the study period.

Ages

18 to 65 years

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Inclusion Criteria: * BPPV Group Age 18 years or older Clinical diagnosis of benign paroxysmal positional vertigo (BPPV) confirmed by positional testing (Dix-Hallpike and/or Roll test) with positional nystagmus No known history of cardiac disease Ability and willingness to provide written informed consent Healthy Control Group Age 18 years or older No history of vertigo or known vestibular disorder Age- and sex-matched to the BPPV group No known history of cardiac disease Ability and willingness to provide written informed consent Exclusion Criteria: * Age younger than 18 years Inability to provide informed consent or impaired mental capacity Known arrhythmia, heart failure, ischemic heart disease, or other clinically significant cardiac disorder Use of medications that may directly affect heart rate variability, including beta-blockers, non-dihydropyridine calcium channel blockers, antiarrhythmic drugs, digoxin, systemic corticosteroids, centrally acting sympatholytic agents, or psychotropic medications that may influence autonomic balance Active infection or systemic inflammatory disease
