Differentiating Persistent Postural-Perceptual Dizziness from Anxiety Disorder Using Behavioral Responses to Complex Visual Environments

/Objectives: Persistent postural-perceptual dizziness (PPPD) and anxiety disorder (AD) share overlapping clinical features that make differentiation with conventional assessments challenging. This study examined whether virtual reality (VR)-based vestibular assessment and immersive phobic scenarios can reveal distinct response profiles between these conditions.

If validated in larger studies, behavioral responses to complex visual environments may offer audiologists and vestibular clinicians a practical tool to differentiate PPPD from anxiety disorder at the point of care.

Accurate differentiation of PPPD from anxiety disorder has direct treatment implications, and a behavioral assessment approach could reduce reliance on lengthy exclusion-based diagnosis.

1. 01PPPD and anxiety disorder share overlapping dizziness and postural symptoms, complicating differential diagnosis.
2. 02Study evaluated behavioral responses to complex visual environments as a differentiating tool.
3. 03Visual environment provocation may elicit distinct postural and perceptual responses in PPPD vs. anxiety patients.
4. 04Findings could support earlier, more accurate diagnosis without extensive exclusionary testing.
5. 05Sample size and study design details are critical to interpreting the strength of findings.
