Cognitive Dysfunction in Chronic Rhinosinusitis: A Scoping Review.
Review in International forum of allergy & rhinology, 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
backgroundCognitive dysfunction is increasingly recognized as an extra-nasal manifestation of chronic rhinosinusitis (CRS). This scoping review characterizes the primary evidence on cognition in adult CRS, covering measures, treatment response, and incident dementia.
methodsWe searched EMBASE, PubMed/MEDLINE, Web of Science, the Cochrane Library, CINAHL, and Global Index Medicus through May 2026 using a MeSH and free-text strategy. Inclusion criteria include primary studies of adult CRS with a formal clinical diagnosis (AAO-HNS, EPOS or ICD-coded) reporting at least one validated cognitive measure or recognized cognitive impairment. Two reviewers screened independently. Animal studies, reviews, conference abstracts, and non-CRS populations were excluded. PRISMA-ScR reporting was performed; heterogeneity precluded meta-analysis.
resultsTwenty-four primary studies met inclusion criteria. Adults with CRS perform worse than controls on subjective (Cognitive Failures Questionnaire [CFQ], Neuro-QoL) and objective (Montreal Cognitive Assessment [MoCA], Automated Neuropsychological Assessment Metrics [ANAM], eye movement assessment, P300) cognitive instruments. Deficits correlate with disease-specific QoL severity (SNOT-22, Rhinosinusitis Disability Index [RSDI]). Cognitive measures improve after medical therapy or endoscopic sinus surgery. Two resting-state fMRI analyses identified altered orbitofrontal-precuneus connectivity scaling with sinonasal inflammation. Dementia results are mixed: a UK Biobank analysis (7176 CRS cases among 364,945 participants) reported increased Alzheimer disease risk (HR 1.33), while two Korean cohorts and a 2025 meta-analysis found no association.
conclusionAdults with CRS show measurable cognitive dysfunction that may improve with treatment, with a plausible neuroinflammatory pathophysiology. Whether this translates to incident dementia is contested. Outcome heterogeneity limits synthesis; therefore, development of a CRS-specific cognitive measurement set is recommended.
