Prevalence of persistent postural perceptual dizziness in the general population

Takeaway

  • Persistent postural perceptual dizziness (PPPD) is more prevalent in the general population than previously thought, manifesting as a smooth continuum between the least and most severe cases.

Why this matters

    Subclinical symptoms of PPPD could be associated with naturally occurring variations of visual dependence levels, predisposing patients to more severe PPPD symptoms should they experience a vestibular or brain insult. Therefore, it could be important for physicians to assess dizziness in patients even if this is not the primary complaint, as it could predict for subsequent emergence of severe PPPD.
