Psychological Well-Being, Neuroticism, and the Risk of Benign Paroxysmal Positional Vertigo: A Triangulation Study.
Article in Brain and behavior, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundBenign paroxysmal positional vertigo (BPPV) is frequently accompanied by psychiatric and psychological comorbidities. However, the causal direction underlying the association between mental health traits and BPPV remains actively debated. We aimed to investigate the relationship between psychological well-being, neuroticism, and BPPV risk using a comprehensive triangulation framework.
methodsWe integrated three distinct methodological paradigms. First, we conducted a cross-sectional analysis using data from the National Health and Nutrition Examination Survey (NHANES, N = 3842). Second, we analyzed longitudinal cohort data from the UK Biobank (N = 401,265; median follow-up: 12.4 years). Finally, we applied bidirectional two-sample Mendelian randomization (MR) utilizing large-scale genome-wide association studies and FinnGen datasets to infer genetic causality.
resultsCross-sectional analysis revealed that higher life satisfaction was associated with significantly lower odds of BPPV symptoms. Longitudinally, survival analysis of the UK Biobank cohort demonstrated that higher neuroticism was inversely associated with the risk of incident BPPV, whereas high life satisfaction acted as a robust inverse correlate. Forward MR analysis corroborated a suggestive inverse genetic association of life satisfaction and positive affect against BPPV, alongside a risk-mitigating effect of emotional lability and neuroticism. Importantly, reverse MR analysis found no evidence of reverse causality from BPPV to mental health traits.
conclusionsConsistent multi-method evidence is suggestive of a potential relationship where favorable psychological states demonstrate an inverse association with BPPV, while neuroticism is associated with decreased clinical incidence, challenging previous assumptions. These findings identify an intriguing association between psychological traits and vestibular health that warrants further investigation and independent replication before any clinical preventive implications can be proposed.
