Perceptual Dizziness is a clinical construct within the domain of neuro-otology that denotes a persistent vestibular disorder characterized by non-vertiginous dizziness, unsteadiness, and heightened sensitivity to visual motion or complex visual environments, distinguished from other forms of dizziness by its chronicity, postural exacerbation, and perceptual misprocessing of spatial and motion cues in the absence of active vestibular pathology.
