The phrase “persistent postural-perceptual dizziness” and its acronym “PPPD” were used.
From 318 articles, 15 were selected for full analysis with respect to PPPD. Most were case-control studies, with one consensus paper from the Bárány Society available. Overall, the pathophysiology of PPPD remains relatively poorly understood, but is likely to be a maladaptive state to a variety of insults, including vestibular dysfunction and not a structural or psychiatric one. Cognitive behavioral therapy, vestibular rehabilitation, selective serotonin uptake inhibitors (SSRIs), and serotonin-norepinephrine reuptake inhibitors (SNRIs) all seem to have a role in its management.
PPPD is useful as a diagnosis for those treating dizziness as it helps to define a conglomeration of symptoms that can seem otherwise vague and allows for more structured management plans in those suffering from it.
