Understanding Persistent postural-perceptual dizziness (PPPD)
The diagnostic pattern includes dizziness, unsteadiness or non-spinning vertigo on most days for at least three months, exacerbated by upright posture, motion and moving or complex visual stimuli. The full criteria and alternative explanations require clinician assessment. [1] [2]
PPPD may begin after a vestibular or other medical event and can coexist with conditions such as vestibular migraine. Functional describes altered operation of balance/perceptual systems, not deliberate symptoms or a mandatory psychiatric cause. [1]
One condition. Different experiences.
Experiences can vary with the cause, task and person. These descriptions are examples, not a checklist for self-diagnosis.
What is happening—and what remains uncertain
Balance uses vestibular, visual and body-position information. PPPD models involve altered weighting, vigilance and postural control after an initiating event, with continuing interactions among these systems. [1]
There is no single established imaging biomarker that diagnoses the condition. The clinical pattern is positively identified while checking whether another active disorder better explains some or all symptoms. [1] [5]
What can look similar?
Vestibular migraine
Episodic migraine-related vestibular symptoms and persistent PPPD can overlap, but the diagnostic time pattern and assessment differ. [1]
BPPV or other vestibular disease
Brief position-triggered vertigo and other peripheral disorders require their own examination and treatment; they should not be presumed from a busy-scene symptom. [1]
Anxiety versus cause
Anxiety can coexist or influence symptoms, but it is not required to prove PPPD and does not mean the dizziness is chosen. [1]
Similar-looking symptoms can have different causes. A matching picture cannot establish a diagnosis.
What an assessment may involve
- Establish the patternHistory covers duration, posture, movement, visual triggers, precipitating events and actual functional impact. A symptom list alone is not enough. [1]
- Examine alternatives and comorbidityVestibular, neurological, ocular and medical assessment is selected from the history, including medication or orthostatic contributors when relevant. [1] [5]
- Set a functional baselineThe clinician and rehabilitation team identify meaningful activities and tolerable measures of progress rather than repeatedly provoking severe symptoms online. [1] [5]
What may help—and what is still being studied
Explain the diagnosis and coexisting disorders
A clear clinical explanation can connect symptoms, triggers and the plan without suggesting structural damage that has not been found. [1] [5]
What this can mean for daily life
Plan pacing with a professional
Agree manageable participation goals and a progression plan rather than forcing severe exposure or avoiding all motion indefinitely. [1] [5]
Adjust visual demands
Reduce unnecessary scrolling or competing patterns where useful, while working toward chosen real-world activities with the team. [1] [5]
Track function and different symptoms
Note what activities are limited and report a new or changed pattern instead of assuming all dizziness has one cause. [1]
Connect with vestibular peers
VeDA’s directory includes local and online groups; personal stories can provide support but not predict which treatment will work. [4]

Research, with the context left in
Selected studies and guidance, with their populations and limitations. These are curated educational summaries, not a complete systematic review or a formal evidence rating.
Diagnostic criteria for PPPD — Bárány Society consensus
Defines persistent posture-, motion- and visually exacerbated symptoms with required clinical context. [1]
Limits and applicability: Consensus criteria are not a biomarker or a treatment-effect trial.
Pharmacological interventions for PPPD
Found no eligible trials answering that specific efficacy-and-harm question. [2]
Limits and applicability: Absence of eligible evidence is not proof of no benefit; search dates and eligibility differ from later broader reviews.
Effect of conservative therapy for PPPD
Reports favorable pooled findings for some combined approaches. [6]
Limits and applicability: Heterogeneity, comparator choice, risk of bias and limited follow-up restrict certainty and do not establish universal treatment superiority.
Questions researchers still need to answer
- Which treatments produce durable participation gains in rigorous placebo- or attention-controlled studies?
- How can outcomes account for coexisting vestibular disease and individual trigger patterns?

Questions you may still have
Is PPPD simply poor eyesight?
No. Visual environments can provoke vestibular symptoms without ordinary acuity loss explaining the problem. [1]
Does functional mean the symptoms are voluntary?
No. It describes a functional vestibular disorder, not deliberate production of symptoms. [1]
Can vestibular migraine coexist?
Yes. Coexisting diagnoses can each contribute and should be identified rather than collapsed into one label. [1]
