The term<unk>  (CSD) is used to describe a commonly encountered type of<unk>  that is not easily categorized into one of several other types, and for which the physical examination is typically normal. Patients with CSD frequently initially suffer a sudden injury of some sort to their vestibular system, the neurologic network that preserves sense of balance. Even after this initial injury has healed, people with CSD usually describe a vague sense of unsteadiness worsened by triggers in their environment such as high places, standing on moving objects, or standing in motion-rich environments like busy streets or crowds. There is a clear indication that anxiety and other mental illnesses play a role in the<unk>  symptoms that occur with CSD. However, the condition is categorized as<unk>  functional vestibular disorder, not as a structural or psychiatric condition. Proposals include renaming it persistent postural-perceptual<unk>  (PPPD) which better captures the multiple aspects of the condition under its title. It is under that title the World Health Organization has included PPPD in its draft list of diagnoses to be included to the next edition of the International Classification of Diseases (ICD-11) in 2017.
