Abstract

BACKGROUND: Persistent postural perceptual dizziness (PPPD) is a common chronic condition presenting in neurology and neuro-otology clinics. Symptoms lie on a spectrum in the general population. The cause is unknown and thought to involve interactions between visual and vestibular systems, but symptoms also correlate with anxiety and migraine. OBJECTIVE: To test whether PDDD symptoms are associated with reported differences in other senses (touch, hearing, smell and taste); to investigate possible mediation via anxiety or migraine; to discover the proportion of variance accountable to these non-vestibular factors. METHODS: We measured self-report multisensory sensitivity, anxiety, visual difficulties, visual discomfort and migraine in patients with PPPD (N = 29) and a large general population cohort (N > 1100). We used structural equation modelling to examine relationships between the factors using a step-wise approach. RESULTS: We found increased self-reported over-sensitivity in sensory domains beyond vision and balance in both patients with PPPD and non-clinical participants with more PPPD symptoms. SEM analysis revealed that anxiety partly, but not wholly, mediated this relationship. Adding visual difficulties and visual discomfort to the model allowed it to explain 50% of PPPD symptom variance. Most of the path coefficients and mediation effects in our model were unchanged between participants with and without migraine. CONCLUSIONS: Our findings support the idea that PPPD is a complex neurological condition that includes broad perceptual factors, and may suggest that some brains are predisposed to generalised cross-modal sensory-overload. This may give rise to vulnerability to severe PPPD should a vestibular insult occur.

  • Few subjective scales are validated for assessing the intensity of visual vertigo, and these scales are limited by recall bias because they require individuals to rate symptoms from memory.

    “Few subjective scales are validated for assessing the intensity of VV, yet these scales are limited by recall bias, as they require individuals to rate their symptoms from memory.”

    From A Pilot Study to Assess Visual Vertigo in People with Persistent Postural–Perceptual Dizziness with a New Computer-Based Tool (2023) · cites this paper as [10]

    The Method > Measures section describes the Visual Vertigo Analogue Scale as a subjective rating of dizziness in nine situations, and the Discussion > Caveats section acknowledges limitations of self-reported ratings. Neither section says that few visual-vertigo scales are validated or identifies recall bias from rating symptoms from memory; the caveat concerns introspection and response bias instead. Page numbers were not available in our copy. (LLM, conf=0.82)

  • People with PPPD tend to avoid provocative situations and activities in daily life, so their VVAS scores may not reflect present reality.

    “People with PPPD tend to avoid provocative situations and activities in daily life, thus, the scoring of the items may not reflect the present reality [10].”

    From A Pilot Study to Assess Visual Vertigo in People with Persistent Postural–Perceptual Dizziness with a New Computer-Based Tool (2023) · cites this paper as [10]

    The Results (Patient cohort comparison; page not supplied) report greater sensory avoidance in patients with PPPD, and the Methods (Measures; page not supplied) identify the VVAS items as situations that trigger visually induced dizziness. The paper does not establish that patients avoid those particular situations in daily life or that avoidance makes VVAS scores unrepresentative of their present condition. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • Avoidant behaviors are common in people with visual vertigo.

    “Such avoidant behaviors are common in people with VV [10].”

    From A Pilot Study to Assess Visual Vertigo in People with Persistent Postural–Perceptual Dizziness with a New Computer-Based Tool (2023) · cites this paper as [10]

    The Results (Patient cohort comparison; page unavailable) report greater sensory avoidance in patients with persistent postural-perceptual dizziness (PPPD) than in a non-clinical comparison group. The paper measures visually induced dizziness, but its avoidance analysis excludes visual and movement items. It therefore supports an association with avoidance, not the specific claim that the avoidant behaviors at issue are common in people with visual vertigo. (LLM, conf=0.78)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
