Is 'persistent postural perceptual dizziness' a helpful diagnostic label? A qualitative exploratory study

Area of Science:

• Neuroscience
• Psychology
• Patient Experience

Background:

• Persistent Postural Perceptual Dizziness (PPPD) is a recently defined functional syndrome.
• Research on patient perspectives of the PPPD label is limited.
• Concerns exist regarding the potential negative impact of diagnostic labels in functional disorders.

Purpose of the Study:

• To explore patient views and understanding of the Persistent Postural Perceptual Dizziness (PPPD) label.
• To investigate how patients interpret and utilize the PPPD diagnosis in their illness narrative.

Main Methods:

• Semi-structured interviews were conducted with 13 individuals diagnosed with PPPD.
• Thematic analysis was employed to analyze the interview data.

Main Results:

• Patients reported reassurance and validation from receiving a label for their condition.
• The PPPD diagnosis led to re-evaluation of illness beliefs, increasing perceived control but also fear of serious consequences.
• Participants frequently misunderstood the terms "persistent," "perceptual," and "postural," and rarely used the term PPPD themselves.
• Distress was normalized, with participants not viewing psychological aspects as integral to PPPD.

Conclusions:

• The PPPD label offers relevance beyond mere classification, providing validation.
• The specific terminology within "Persistent Postural Perceptual Dizziness" is confusing for patients.
• Simplifying the nomenclature could enhance shared understanding, patient engagement, and potentially improve management outcomes.
