What is PPPD?
PPPD (Persistent Postural-Perceptual Dizziness) is a functional vestibular disorder — meaning the inner ear and brain structures are intact, but the way the brain processes balance and spatial information has become dysregulated. It is one of the most common causes of chronic dizziness, particularly in working-age adults.
PPPD was formally defined by the Barany Society in 2017, but the condition has been recognised under different names for decades, including chronic subjective dizziness (CSD) and phobic postural vertigo. These older terms all described the same core problem: the brain's balance system becomes stuck in a heightened state of alert after an initial triggering event.
The trigger is usually a vestibular episode — a bout of vestibular neuritis, BPPV, a concussion, or even a prolonged period of illness or anxiety. The original problem resolves, but the brain continues to behave as though the threat is still present. It over-monitors balance signals, amplifies normal sensory input, and produces persistent dizziness even when nothing is structurally wrong with the inner ear.
Think of it as the brain's "threat detection system" for balance getting turned up to maximum and failing to dial back down. The dizziness is real — it is not imagined or psychological — but the cause is a problem with how the brain is processing information, not damage to the inner ear itself.
Common symptoms
- Persistent non-spinning dizziness or unsteadiness — not the room-spinning vertigo of BPPV, but a constant sense of swaying, rocking, or being "off"
- Worse with upright posture — symptoms increase when standing or walking and tend to ease when sitting or lying down
- Worse in visually complex environments — busy shops, scrolling screens, patterned floors, and crowded spaces intensify the dizziness
- Worse with self-motion or watching movement — walking through open spaces, riding in a car, or watching moving objects can provoke symptoms
- Duration of three months or more — PPPD is by definition a chronic condition, with symptoms present on most days
- Fluctuating severity — symptoms may wax and wane throughout the day or week, often influenced by fatigue, stress, and activity levels
Many patients also report brain fog, difficulty concentrating, fatigue, and increased anxiety — all of which are common secondary effects of living with chronic dizziness.
How is PPPD diagnosed?
PPPD is a clinical diagnosis based on the Barany Society's diagnostic criteria. There is no single test — no blood work, imaging study, or vestibular test — that confirms it. Instead, the diagnosis is made by identifying the characteristic symptom pattern and ruling out other conditions that could explain the symptoms.
At Burlington Vestibular Therapy, your physiotherapist will conduct a comprehensive vestibular assessment that includes:
- Detailed symptom history — mapping the onset, triggers, duration, and behaviour of your dizziness to determine whether it fits the PPPD profile
- Vestibular examination — positional testing, head impulse testing, nystagmus assessment, and balance testing to rule out active conditions like BPPV or ongoing vestibular hypofunction
- Identifying the triggering event — most people with PPPD can point to a specific event (a vestibular episode, illness, injury, or period of intense stress) that started the cycle
- Functional assessment — evaluating how the dizziness is affecting your daily activities, work, and quality of life
If your presentation suggests PPPD, your therapist will explain the diagnosis clearly and outline a treatment plan. Understanding what PPPD is — and what it is not — is itself an important part of recovery, as many patients have spent months searching for a structural cause that does not exist.
How PPPD is treated
PPPD responds well to a combination of vestibular rehabilitation therapy, cognitive-behavioural strategies, and in some cases medication. At Burlington Vestibular Therapy, your treatment will focus on retraining the brain's balance processing through a structured, progressive approach.
Vestibular rehabilitation with habituation focus
The core of PPPD treatment is habituation-based vestibular rehabilitation. This involves controlled, repeated exposure to the movements, postures, and visual environments that provoke your symptoms. By gradually and consistently exposing the brain to these stimuli, the nervous system learns to reduce its exaggerated response.
Your therapist will design a programme that starts well within your tolerance and progresses systematically. Over time, activities that once triggered significant dizziness — walking through a busy store, riding an escalator, turning your head while walking — become manageable again.
Graded exposure to provocative environments
A key component of recovery is progressively re-engaging with the real-world situations that have become difficult. This might include walking in open spaces, navigating crowded environments, using screens for extended periods, or riding in a car. Your therapist will help you build a structured exposure plan so that you can reclaim these activities at a pace that challenges the system without overwhelming it.
Cognitive-behavioural strategies
Because PPPD involves the brain's threat detection and attention systems, addressing the cognitive and behavioural patterns that maintain the cycle is important. This may include strategies to reduce hypervigilance toward balance sensations, manage the anxiety that often accompanies chronic dizziness, and shift attention away from internal monitoring. For some patients, formal cognitive-behavioural therapy (CBT) with a psychologist experienced in chronic dizziness can be a valuable addition to the rehabilitation programme.
Medication
In some cases, your physician may prescribe a low-dose SSRI or SNRI medication to help modulate the brain's sensitivity to balance signals. These medications are not sedatives or vestibular suppressants — they work by adjusting serotonin pathways involved in sensory processing. When used alongside vestibular rehabilitation, they can help lower the brain's baseline reactivity and create a more favourable environment for recovery. Your physiotherapist can discuss this option and coordinate with your physician if appropriate.
How effective is treatment?
The evidence for vestibular rehabilitation in PPPD is strong and growing. Most patients who engage consistently in a structured rehabilitation programme see significant improvement in their symptoms, functional ability, and quality of life.
- Consistent vestibular rehabilitation is the single most important factor in recovery — patients who commit to their home exercise programme and graded exposure plan tend to do well
- Full recovery is common with the right approach, though the timeline is typically longer than for conditions like BPPV — expect weeks to months of steady progress rather than a quick fix
- Combined treatment (VRT plus CBT and/or medication when indicated) tends to produce the best outcomes, particularly for patients with significant anxiety or avoidance behaviour
The most important thing to understand is that PPPD is a treatable condition. The brain created this pattern, and with the right guidance, the brain can unlearn it.
When to seek vestibular therapy for PPPD
If you have been experiencing persistent dizziness or unsteadiness for three months or more — especially if it started after a vestibular episode, illness, or injury, and especially if it worsens in visually busy environments or with movement — PPPD may be the cause.
Many people with PPPD have already seen multiple practitioners and had normal test results, which can be frustrating and confusing. A vestibular physiotherapist with experience in functional dizziness disorders can help you make sense of your symptoms and start a targeted treatment plan.
