Persistent postural-perceptual dizziness (PPPD) can be confusing because tests may look normal while the patient still feels unsteady every day. Meera came to my clinic after two years of chronic dizziness. She’d seen multiple doctors, had extensive testing including MRI and vestibular tests—all normal. She was told “your inner ear is fine, you’re probably just anxious.” She felt dismissed and frustrated. Her dizzy, floating sensation was real, not imaginary. But why was everything normal?

Meera had PPPD—Persistent Postural Perceptual Dizziness. This is a real neurological condition, but it’s not an inner ear problem. It’s a problem with how her brain processes balance information. It’s not “all in your head” in the sense of being psychological—it’s literally in her brain’s wiring.
Today I want to explain PPPD, which is poorly understood by many doctors and even less understood by patients.
Understanding Persistent Postural Perceptual Dizziness
What is PPPD?
PPPD is a diagnosis of exclusion. If a patient has chronic dizziness without any structural cause (normal inner ear exam, normal imaging, normal blood pressure), PPPD becomes the likely diagnosis.
PPPD is a disorder of vestibular processing—the way the brain interprets balance signals. The inner ear itself is functioning normally. The problem is in how signals from the inner ear are being filtered and integrated by the brain.
Why is it called “Persistent Postural Perceptual Dizziness”? – Persistent: The dizziness is chronic, present most days – Postural: Made worse by being upright, standing, or walking – Perceptual: Involves perception and brain processing, not just physical damage – Dizziness: Non-spinning vertigo (rocking, swaying, floating sensation)
What were previous names? This condition has been called “phobic postural vertigo,” “chronic subjective dizziness,” “space and motion discomfort,” and “visual vertigo.” These older names emphasized the psychological component, which was misleading. It’s now called PPPD to better reflect the actual neurological dysfunction.
Three Core Features of PPPD
Feature 1: Non-Spinning Dizziness Present Most Days The patient experiences chronic rocking, swaying, bobbing, or floating sensation. It’s not the room spinning (that would be vertigo). It’s a sense of movement or imbalance. Patients describe it as: – “Like I’m on a boat” – “Like walking on cotton wool” – “Like I’m floating or swaying” – “Like the floor is unstable” – “Like I might fall even though I don’t” This sensation is present most of the day, most days. Unlike episodic vertigo (Meniere’s, BPPV), PPPD is chronic and constant.
Feature 2: Worsened by Upright Posture and Movement The dizziness is worst when standing or walking. It improves when sitting or lying down. Movement makes it worse. Patients feel “anchored” when lying down and “adrift” when standing.
This is why PPPD patients might avoid standing for long periods, might sit down frequently, and might be reluctant to walk.
Feature 3: Made Worse by Specific Visual or Self-Motion Stimuli Certain visual environments and movements trigger or worsen symptoms: – Crowds and busy environments – Shopping malls or large stores with lots of people and movement – Busy traffic or driving (especially as a passenger) – Scrolling phones or reading text – Television or movies with moving scenes – Patterns or stripes – Rain or snow falling – Escalators or moving walkways – Visual motion (watching people walk past, etc.)
These aren’t random triggers—they’re specifically situations with complex visual information or visual motion that conflicts with the patient’s internal sense of movement.

What Causes PPPD?
PPPD usually starts after a triggering event. Common triggers include:
- Acute vestibular event: Labyrinthitis, vestibular neuritis, or a period of severe true vertigo
- BPPV: After treating BPPV, some patients develop persistent dizziness
- Panic attack or anxiety episode: Severe anxiety about balance can trigger PPPD
- Illness or stress: During or after a major illness or very stressful period
- Physical injury: Head trauma or other injury
But here’s the key: PPPD doesn’t start because of ongoing inner ear dysfunction. Once the initial event (like vestibular neuritis) has resolved, the patient should feel better. But they don’t. Their brain has developed a maladaptive response where it amplifies and misinterprets normal balance signals.
The brain wiring problem: Normally, your brain integrates vestibular information (inner ear), visual information (eyes), and proprioceptive information (body position sense) to create a stable perception of your body in space.
In PPPD, the brain becomes hypervigilant to balance threats. It amplifies normal postural signals. It overestimates actual sway. It becomes hypersensitive to visual motion. The result: the patient perceives dizziness and instability that objectively isn’t there.
This is compounded by personality factors—patients with PPPD often have type A personalities, perfectionist traits, high health anxiety, and tendency toward catastrophic thinking.
Who Gets PPPD?
PPPD typically affects people in 40s-50s, though it can occur at any age. It’s more common in women. Common personality traits in PPPD patients: – Anxious personality – Perfectionist or high-achiever – Health-conscious or health-anxious – Tendency to monitor symptoms closely – Tendency toward catastrophic thinking (“this dizziness will make me fall” or “I might faint”)
It’s not true that PPPD patients are “crazy” or “just anxious.” They’re not malingering or attention-seeking. They have a real neurobiological condition. But their personality and anxiety amplify the symptoms.
Diagnosis of PPPD
Since PPPD is a diagnosis of exclusion, we first rule out other causes:
Testing typically includes: – Detailed history of dizziness pattern – Head impulse test (eye movement reflex) – Dix-Hallpike and other positional maneuvers – Audiogram (normal in PPPD) – Video nystagmography (eye movement tracking) – Sometimes: MRI brain to rule out MS or other CNS disease – Sometimes: ECG to rule out cardiac arrhythmia – Sometimes: blood pressure and blood glucose monitoring
The tests are usually normal. This can be frustrating for patients who want a “diagnosis,” but normal testing combined with the characteristic history IS the diagnosis.

Red flags suggesting PPPD over other diagnoses: – Chronic symptoms (months to years) – Non-spinning dizziness (floating, swaying, rocking) – Worsened by visual complexity – Worsened by movement – Worsened by crowds – No hearing loss – Normal objective vestibular tests – Significant health anxiety

Treatment of PPPD
Treatment requires multiple approaches working together:
1. Vestibular Rehabilitation Therapy (VRT) This is the most evidence-based treatment. VRT involves graded exposure to vestibular and visual stimuli that provoke dizziness, with the goal of habituation (your brain learns these stimuli are harmless).
Specific exercises for PPPD: – Visual motion desensitization (watch scrolling patterns, moving objects) – Head movements while tracking moving targets – Gaze stabilization exercises – Walking in complex environments (controlled exposure) – Walking while doing upper body movements – Exposure to busy visual environments
A physical therapist trained in vestibular rehabilitation designs the program. Sessions happen 1-2 times per week for 6-12 weeks. Home exercises are done daily. Success requires months of consistent effort.
2. SSRIs/SNRIs (Antidepressants) Despite being called “antidepressants,” SSRIs and SNRIs help PPPD because they modulate central vestibular processing. They’re not given because PPPD is “just anxiety”—they’re given because they’re neurochemically effective for vestibular processing disorders.
Common medications: – an SSRI medication (Sertima, Zoloft) starting 50- – an SNRI medication (Effexor) 150- – Clomipramine (older tricyclic, effective but more side effects) These take 4-6 weeks to show benefit and are often continued for 6-12 months. Combination with VRT is more effective than either alone.
3. Cognitive Behavioral Therapy (CBT) CBT helps patients recognize and change maladaptive thought patterns like catastrophizing. “If I feel dizzy, I might faint” becomes “I’m dizzy but I won’t faint. This sensation is uncomfortable but harmless.”
In India, CBT is expensive and not widely available. Psychoeducation (explaining the condition and natural history) can provide benefit even without formal CBT.
4. Vestibular Suppressants to AVOID Medications like a vestibular suppressant, dimenhydrinate, and benzodiazepines might seem helpful for dizziness, but they actually make PPPD worse in the long term. They prevent habituation and reinforce the fear response. These should be avoided.

5. Exercise and Activity Walking is therapeutic for PPPD. Progressive exposure to real-world situations (busy markets, crowded areas) is better than avoidance.
The Indian Context: Challenges with PPPD
In India, there are specific challenges with PPPD diagnosis and treatment:
1. Stigma of “mental” component: Patients are reluctant to accept that PPPD has a psychological component. They want a clear “ear disease” diagnosis.
2. Limited access to VRT: Physical therapists trained in vestibular rehabilitation are rare outside major cities.
3. Limited access to CBT: Mental health services are limited and expensive.
4. Cultural factors: In Indian families, anxiety is sometimes seen as weakness. Talking about anxiety or psychological symptoms carries social stigma.
5. Medication cost: Long-term SSRI therapy is needed for 6-12 months, which accumulates cost.
Despite these challenges, PPPD is manageable with proper explanation and commitment to treatment. Many patients respond well once they understand the condition and begin vestibular rehabilitation.
Realistic Expectations
– PPPD is not curable, but very treatable – Improvement takes weeks to months, not days – Treatment requires active participation—it’s not a pill that fixes everything – Some patients see 80-90% improvement; others see 30-50% improvement – Stress and anxiety can cause flare-ups even during treatment – Long-term follow-up is often needed
