Brain activation in persistent postural-perceptual dizziness (PPPD) in response to various visual motion stimuli eliciting abnormal egomotion perception.

BACKGROUND Patients with persistent postural-perceptual dizziness (PPPD) perceive unsteadiness associated with abnormal ego- or visual motion perception. We tested for altered functional brain activation of PPPD patients and healthy subjects (HC) while applying various visual motion stimuli (VS). METHODS Functional b...

Abnormal visual-vestibular cerebro-cerebellar connectivity in persistent postural-perceptual dizziness

Objective: Patients with persistent postural-perceptual dizziness (PPPD) perceive unsteadiness associated with abnormal ego- or visual motion perception. Maladaptive multisensory integration and visual dependency have been proposed implicating abnormal functional connectivity (FC). Based on the crucial impact of the ce...
