Impact of Hearing Loss on Memory Loss in Patients With Self-Reported Olfactory Dysfunction.
Article in Cureus, 2025. 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
Introduction The association between hearing loss and dementia, and olfactory dysfunction (OD) and dementia, respectively, is well-elucidated. Several neurodegenerative diseases, including Alzheimer's disease and Parkinson's disease, impact the olfactory system early in their progression. Despite these established correlations, the independent effect of hearing loss on memory in patients with self-reported olfactory dysfunction is poorly elucidated, which this study aims to investigate, especially in light of the prevalence of anosmia post-COVID-19. Methods A total of 591 records of adult patients with self-reported olfactory dysfunction without a history of traumatic brain injury (TBI) from 2015 to 2020 from a single academic institution were analyzed. Patients were stratified based on demographic, memory loss (including mild cognitive impairment (MCI)), and clinical factors. Univariate and multicollinearity analyses assessed for correlations, with significant covariates utilized in a logistic regression model. Results In univariate analyses, hearing impairment (p<0.001), history of stroke (p<0.001), coronary artery disease (CAD) (p<0.001), hypertension (HTN) (p<0.001), and obstructive sleep apnea (OSA) (p=0.020) were significant. Primary language spoken, smoking history, myocardial infarction (MI), and diabetes mellitus (DM) were not significant. In logistic regression, hearing impairment was significantly associated with memory loss (p<0.001). Other significant covariates included stroke (p=0.004), CAD (p=0.022), and HTN (p<0.001). Conclusions Our results show that hearing impairment is significantly associated with memory loss, specifically in patients with self-reported olfactory dysfunction. This highlights the increased risk of memory loss in this population, underscoring the need for further research into screening and pathophysiology of memory loss in hard-of-hearing patients with olfactory dysfunction post-COVID-19.
