Sleep disturbance and cognitive trajectories among older adults with subjective cognitive decline: the roles of age and sleep treatment.
Article in Sleep, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
STUDY
objectivesGrowing evidence indicates that subjective cognitive decline, characterized by self-reported cognitive deterioration without measurable cognitive impairment, may be an early indicator of Alzheimer's Disease. This study investigated the association between baseline sleep disturbance and a 10-year trajectory of global cognitive performance in adults with subjective cognitive decline and examined if this association was moderated by age (50-64 years and ≥65 years) and sleep treatment.
methodsUsing six waves (2010-2020) of the Health and Retirement Study, we included individuals aged ≥50 years who reported subjective cognitive decline but had no objective cognitive impairment at baseline (2010) and had the final wave of cognitive data (N = 1372). Latent growth curve modeling was employed to examine the associations between self-reported sleep disturbance and cognitive trajectories from 2010 to 2020, controlling for sociodemographic and health-related factors.
resultsIn the full sample, baseline sleep disturbance was not significantly associated with cognitive change. However, a significant interaction between sleep disturbance and age group was found (β = -0.04, 95% confidence interval [-0.08, -0.003]). Stratified analyses showed that poorer sleep was associated with faster cognitive decline in those aged ≥65 years (β = -0.04, 95% confidence interval [-0.07, -0.005]; n = 558), and using sleep treatment was associated with a reduced impact of sleep disturbance on cognitive decline (β = 0.31, 95% confidence interval [0.02, 0.60]). These associations were not significant in those aged 50-64 years (n = 814).
conclusionsSleep disturbance was an independent risk factor of future cognitive decline in older adults ≥65 years with subjective cognitive decline. Sleep treatment may mitigate this decline, offering a potential intervention strategy.
