Persistent Postural-Perceptual Dizziness / 대한평형의학회지

ABSTRACT

Persistent postural-perceptual dizziness (PPPD) was derived from phobic postural vertigo and chronic subjective dizziness. Two key physical symptoms of PPPD are postural unsteadiness and visually induced dizziness. Although the underlying mechanism of PPPD is still enigmatic, the prognosis is good with adequate treatment. In this paper, diagnostic criteria, pathophysiology and treatment regarding PPPD will be reviewed.
