What is PPPD?
PPPD stands for persistent postural-perceptual dizziness. PPPD is a chronic dizziness disorder in which people feel persistent unsteadiness or non-spinning dizziness. Symptoms typically begin after a prior vestibular insult, a neurological event, or a period of severe stress. The condition is thought to arise when the brain fails to re-adapt, leaving the postural control system overly dependent on visual and spatial cues and highly sensitive to self-motion.
How CBT helps
Cognitive behavioral therapy, or CBT, is a structured psychological treatment that targets the thoughts, emotions and behaviours that maintain the dizziness. In PPPD, fear of dizziness often drives avoidant behaviour, such as avoiding crowded shops or busy visual scenes. CBT helps patients learn that dizziness does not signal a catastrophic physical problem. Through cognitive restructuring, patients learn to view dizziness as an uncomfortable but harmless nerve signal rather than a sign of collapse or disease.
CBT also uses exposure therapy. Patients gradually confront the visual and postural situations they fear, without relying on safety behaviours such as grabbing a wall or sitting down immediately. Repeated exposure allows the nervous system to habituate and reduces the extreme vigilance that makes the balance system overactive.
Typical CBT techniques in PPPD
- Psychoeducation about the interaction between balance, anxiety and attention
- Cognitive restructuring of catastrophic thoughts about dizziness
- Graded exposure to provocative visual environments and head movements
- Behavioural experiments to test feared predictions
- Relaxation training to reduce generalised anxiety
- Attention training to reduce monitoring of bodily sensations
The role of TRT in PPPD
TRT is an abbreviation for tinnitus retraining therapy. TRT was developed as a habituation-based treatment for tinnitus, and it involves structured counselling combined with sound enrichment to reduce the brain's negative reaction to internal noises. Because symptoms of tinnitus and dizziness may overlap in some patients, there is occasional confusion about whether TRT can treat PPPD.
In fact, TRT is not a primary treatment for PPPD. PPPD is a disorder of postural balance and spatial perception, whereas TRT targets auditory phantom perception. A person with PPPD who also has troublesome tinnitus may be offered TRT for the tinnitus component, but the dizziness component of PPPD is better addressed with CBT and vestibular rehabilitation. Using TRT alone for PPPD is unlikely to change the unsteadiness that the patient experiences during walking or visual motion.
CBT within an overall treatment plan
The recommended treatment for PPPD generally includes a combination of CBT, vestibular rehabilitation therapy (VRT), and in some cases pharmacotherapy. VRT uses balance exercises to retrain the brain-body relationship, while CBT teaches the brain to stop reacting to dizziness with alarm. Some clinical guidelines describe CBT and VRT as complementary, since CBT reduces the anxiety that blocks habituation, while VRT provides the physical practice required for neural recovery.
Medication may also be considered by a treating physician. Antidepressant agents such as selective serotonin reuptake inhibitors (SSRIs) or serotonin-norepinephrine reuptake inhibitors (SNRIs) are sometimes used off-label in the treatment of PPPD, particularly when anxiety or panic is prominent.
Outcome and prognosis
CBT is considered one of the most effective treatment options for PPPD. Many patients report significant reductions in dizziness-related disability, avoidant behaviour and distress after a course of CBT. The effect is strongest when the therapy is delivered by a clinician familiar with vestibular disorders and combined with structured balance exercises.
For any patient with PPPD, an early diagnosis and an explanation of the mechanism behind the symptoms can itself reduce fear. Successful treatment relies on consistent engagement with therapy, gradual re-entry into avoided situations, and patience with the nervous system's relearning process.
