Summary
Persistent postural-perceptual dizziness (PPPD) is a common chronic vestibular disorder causing prolonged dizziness. Diagnosis relies on patient history, as standard tests are often inconclusive.
Area of Science:
- Neurology
- Otolaryngology
- Psychiatry
Background:
- Persistent postural-perceptual dizziness (PPPD) is the most prevalent chronic vestibular disorder.
- Characterized by non-rotational dizziness and instability lasting over three months.
- Symptoms worsen with upright posture, movement, and visual stimuli.
Approach:
- This review focuses on diagnostic questionnaires for PPPD.
- Highlights the reliance on clinical history due to negative objective tests.
- Discusses criteria established by the Barany Association.
Key Points:
- PPPD is a functional disorder, often presenting with normal vestibular and imaging results.
- Diagnostic criteria emphasize subjective patient history.
- Questionnaires aid in the consistent identification of PPPD.
Conclusions:
- Accurate diagnosis of PPPD is crucial for effective management.
- Questionnaires are valuable tools for assessing and diagnosing PPPD.
- Further research into standardized diagnostic tools is warranted.
