- Clinical science
Persistent postural-perceptual dizziness (PPPD), originally known as phobic postural vertigo (PPV), is an idiopathic disorder that presents with a persistent sensation of non-rotational dizziness or unsteadiness and hypersensitivity to motion, lasting at least 3 months. It is the most common cause of chronic dizziness and it often follows an event that caused acute vertigo or dizziness, such as vestibular neuritis or panic attacks. Typically, patients recover from the initial acute disease, but the feeling of dizziness persists. Treatment consists of vestibular rehabilitation, psychotherapy and, if necessary, SSRIs.
- Most common vestibular disorder in people 30–50 years of age
Epidemiological data refers to the US, unless otherwise specified.
- Persistent sensation of non-rotational dizziness or unsteadiness for at least 3 months

- Dizziness typically worsens with motion of both the patient and his or her surroundings
- PPPD patients often suffer from anxiety and/or depressive disorders
There are no tests for PPPD and physical examination is usually unremarkable.
