PPPD: the dizziness that stays after the inner ear has healed.

Rocking, swaying, floating, unsteady in supermarkets and on screens. The tests are normal. The problem is real, and it is in how the brain balances.

This page is about understanding the condition and the role the brain and nervous system can play in it. It is not a diagnosis. Your own clinicians know your case.

What PPPD is

Persistent postural-perceptual dizziness was formally defined by the Bárány Society in 2017. The core criteria: one or more symptoms of dizziness, unsteadiness or non-spinning vertigo on most days for at least three months, made worse by standing or walking, by movement, and by moving or complex visual scenes such as supermarket aisles, scrolling screens or traffic. Symptoms usually begin after an event that disrupts balance, such as vestibular neuritis, benign positional vertigo, vestibular migraine, a panic attack, a concussion or a medical illness.

What makes PPPD distinct is that the original problem resolves and the dizziness does not. People describe rocking, swaying, floating, or feeling as if the floor is moving. Walking becomes cautious and stiff. Busy places become exhausting. Many develop anxiety about falling and start avoiding movement, which makes everything worse.

Because it is a functional disorder, diagnosis is made on the pattern of symptoms rather than on a test result, and by excluding other causes. Hearing tests, balance tests and MRI are typically normal.

The neuroplastic contribution

The ATNS Index of Neuroplastic Symptoms describes PPPD as a functional neurological disorder and notes that diagnostic tests and conventional imaging are usually negative. When that is the case, it says, evaluation for neuroplastic symptoms is appropriate.

Neuroplastic symptoms are real, physical symptoms produced by learned pathways in the brain and nervous system rather than by ongoing damage. PPPD is almost a textbook case. When balance is disturbed, the brain sensibly shifts into a high-alert mode: it relies more on vision, stiffens posture, and monitors every sway. That is the right response to an acute inner-ear problem. In PPPD the inner ear recovers, but the brain keeps running the emergency strategy. Vision-dependent balance makes busy visual scenes overwhelming; stiff, vigilant posture makes ordinary sway feel like falling; constant monitoring amplifies tiny signals into dizziness. The result is real, disabling and visible on no scan, because the structures are intact and the processing has changed.

This is not imaginary, and it is not 'just anxiety', though anxiety usually joins in. It is a learned balance strategy, and the brain can learn a better one. The same model underlies functional neurological disorder more broadly.

• Dizziness that is constant or near-constant rather than in attacks.
• Worse in supermarkets, on screens, in crowds and when walking.
• Better lying down, distracted, or during engaging activity.
• Anxiety, avoidance and a stiff, careful gait.

What the research shows

The Bárány Society's consensus document on diagnostic criteria for PPPD sets out the condition and summarizes early treatment evidence, including a small study in which people with emerging symptoms who received three sessions of cognitive behavioural therapy within eight weeks of onset showed reduced dizziness and avoidance, with benefits lasting to six-month follow-up.

A 2022 review of PPPD's precipitating conditions, co-morbidities and treatment with cognitive behavioural therapy, drawing on 198 cases, reported that CBT produced impressive reductions in anxiety and in measures of dizziness over follow-up periods of up to six months. A 2026 study of subjective-objective dissociation in PPPD confirmed the central puzzle, patients feel very unsteady while objective balance measures are near normal, and reported improvement with neurologist-led multimodal therapy combining education, vestibular rehabilitation and psychological approaches.

Brain imaging is exploratory but points the same way. A review of PPPD from brain imaging to behaviour and perception describes altered activity and connectivity in regions that integrate visual, vestibular and threat signals, including reduced activation in the anterior cingulate cortex and precuneus in early fMRI work, and a 2026 resting-state study reported altered spontaneous brain activity and connectivity. These findings support PPPD as a disorder of processing rather than structure, with the caveat that samples are small and findings are not yet consistent enough for diagnosis. The treatment studies, meanwhile, are the first evidence that retraining the brain's balance strategy works. For how a sensitized system produces symptoms, see central sensitization explained.

Signs the brain may be part of the picture

• Your hearing, balance and imaging tests are normal, or an earlier inner-ear problem has resolved.
• Dizziness is present most days and has lasted more than three months.
• It is worse upright, in motion, and in visually busy places, and eases when you lie down or are absorbed.
• You walk carefully, hold onto things, and avoid crowds, screens or driving.
• Symptoms started after vertigo, migraine, a panic attack, concussion or an illness.
• You feel anxious about falling and monitor your balance constantly.

A solution that addresses it

There is an approach that addresses the brain's balance strategy: symptom reprocessing, which in PPPD sits alongside vestibular rehabilitation. It starts with education, so the dizziness makes sense as an emergency program that never switched off rather than a hidden disease. It uses somatic tracking to notice sway and unsteadiness with curiosity instead of alarm, practices that lower threat and loosen vigilant posture, a graded return to walking, busy places and screens, emotional awareness and expression, and acceptance and commitment skills for living while the system recalibrates. Vestibular physiotherapists and clinicians trained in these methods deliver it, and digital programs increasingly support daily practice.

Cindra is a daily AI companion built around these approaches, with daily check-ins, short practices and plain-language lessons for people whose symptoms have a neuroplastic component. If your dizziness has outlasted its cause, you can join the waitlist.

What to do next

Make sure the diagnosis is right. Seek urgent care for dizziness with sudden severe headache, double vision, slurred speech, weakness or numbness, difficulty walking that came on suddenly, chest pain, or fainting. See a clinician for new hearing loss, spinning vertigo attacks, or dizziness after a head injury. Ask for a neurologist or vestibular specialist to confirm PPPD using the Bárány criteria, and do not stop any medication without discussing it.

Once PPPD is confirmed, ask about vestibular rehabilitation and whether your pattern fits neuroplastic symptoms, which in PPPD it usually does. Then start learning and practising, and begin graded exposure to the places and movements you have been avoiding. Pacing matters: small, repeated, tolerable exposures teach the brain more than occasional heroic ones.

This article is for general education and is not medical advice, and it does not diagnose or treat any condition. Persistent symptoms deserve a proper medical assessment to rule out disease or injury before a neuroplastic explanation is considered. If your symptoms are new, changing, or come with red-flag signs such as fever, unexplained weight loss, numbness or weakness, chest pain, or loss of bladder or bowel control, see a clinician promptly.
