Persistent postural-perceptual dizziness (PPPD) is a chronic functional disorder of the nervous system, characterized by non-spinning vertigo and perceived unsteadiness. The symptoms are exacerbated when patients assume upright postures and in situations with complex or moving visual stimuli. The most common provocations are benign circumstances such as standing, walking, looking at traffic or sitting in a busy restaurant, which may be perceived as noxious or threatening.
