Objective:

To investigate the underlying mechanisms of functional dizziness (FD) and its impact on spatial cognition.

Key Findings:
  • PPPD patients showed significant cognitive deficits in allocentric navigation compared to controls.
  • Velocity storage misalignment in MdDS may worsen symptoms if not properly addressed.
  • VRT improved quality of life in PPPD patients, but anxiety and depression were independent predictors of poorer outcomes.
Interpretation:

Functional dizziness is characterized by dysfunction in the brain's processing of sensory information rather than peripheral vestibular damage.

Limitations:
  • The retrospective design of the VRT study limits the strength of conclusions.
  • Caution is needed in generalizing findings from experimental settings to broader clinical practice.
Conclusion:

Understanding FD as a disorder of sensory integration and spatial cognition can inform more effective therapeutic approaches.
