Persistent Postural-Perceptual Dizziness (PPPD)
PPPD is chronic unsteadiness that worsens upright, in motion, and in busy visual spaces. We calm the threat system first, then retrain how the brain weighs vision and balance.
What you may be noticing
A constant sense of rocking, swaying, or floating that has lasted months. It worsens when you stand or walk, when you move, and in places full of visual motion: grocery aisles, scrolling screens, traffic, patterned floors. Lying down helps. Often it began after a real event, such as vertigo, a viral illness, a concussion, or a panic episode, and the dizziness simply never left.
New dizziness with weakness, numbness, slurred speech, double vision, or a severe headache needs emergency care first.
Why it is rarely one thing
PPPD is a recognized functional vestibular disorder, defined by symptoms on most days for at least three months. It is not imagined, and it is not structural damage. It is a change in how the brain processes balance information.
After an acute dizzy event, the brain wisely shifts into a high-alert strategy. It stiffens posture, leans heavily on vision, and monitors every sensation of motion. In PPPD, the brain keeps running that strategy long after the crisis has passed. Research describes altered connectivity between vestibular, visual, and threat-processing networks, and the exact mechanism is still being studied.
This is the clearest example of a principle at the center of my work: the brain predicts from prior experience. Telling yourself to relax has limited effect, because the system needs new, accurate sensory input. Not a broken inner ear, but a balance system conditioned toward protection. The same plasticity that locked in the alarm can release it. Vestibular rehabilitation, cognitive approaches, and medication prescribed by your physician each help many people, and progress is usually measured in weeks and months.
Patterns we look for
- The original trigger and any residual vestibular weakness.
- Visual dependence: how strongly your balance relies on what your eyes see.
- Postural stiffening of the neck and trunk.
- Autonomic balance, breathing mechanics, and sympathetic overdrive.
- Vigilance and body scanning that amplify signal.
- Migraine and vestibular migraine overlap.
- Cervical proprioception after neck injury.
- Sleep quality, blood sugar stability, and inflammatory load.
How I evaluate it
The comprehensive functional neurological exam maps the vestibulo-ocular reflex, saccades, smooth pursuit, optokinetic responses, balance under changing sensory conditions, cervical proprioception, and autonomic responses to standing. This shows how your brain is weighting each sensory input, and where it is still bracing.
Functional labs are guided by history and may include a thyroid panel, ferritin, vitamin D, B12, and blood sugar markers. I coordinate with your physician on any medication.
How we address it
Regulation comes before endurance. Each layer is added only when the one beneath it feels stable.
- Address any remaining vestibular, migraine, or cervical driver.
- Calm the threat system first: slow nasal breathing with a long exhale, vagal tone training, and daily downshift routines.
- Release postural bracing with movement that rebuilds natural sway and trust in the ground.
- Train gaze stability, smooth pursuit, and cerebellar integration in short, frequent sessions below your symptom threshold.
- Reduce visual dependence with graded optokinetic and visual motion exposure.
- Support the terrain beneath the brain: sleep, steady blood sugar, and lower inflammatory load.
- Progress into real environments, step by step: stores, screens, crowds.
The brain that chose to brace can be retrained to relax. Steadiness is a skill your nervous system can recover.
