People who suffer from persistent postural-perceptual dizziness (PPPD) experience unsteadiness, non-spinning vertigo and dizziness. These symptoms are exacerbated by movement, upright posture, and visual stimuli. In a new study, scientists have tried to find out if these exacerbating factors are present in the period before PPPD is diagnosed. They found that patients developing PPPD are likely to have them early on after the onset of balance disorder symptoms.
