Linking modifiable risk factors to vascular and neurodegenerative brain changes.
Article in GeroScience, 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
Dementia reflects vascular and neurodegenerative processes in late life, yet studies often examine risks and outcomes individually. This study tested whether the cumulative burden of risks relate to vascular brain injury and cognitive performance and whether brain markers are associated with part of these associations through cross-sectional indirect pathways. Cross-sectional data were drawn from 38,414 older adults in the National Alzheimer's Coordinating Center database. A composite index summed ten binary risk factors: hypertension, diabetes, hypercholesterolemia, alcohol misuse, smoking, depression, obesity, hearing loss, vision loss, and low education. Outcomes included white matter hyperintensities (WMHs), infarcts, hippocampal atrophy, global cognition, cognitive status, delayed recall, and semantic fluency. Higher cumulative risk burden was associated with poorer cognitive outcomes and greater structural brain injury. Each additional risk factor was linked to worse global cognitive status, greater clinical severity, lower delayed recall, lower semantic fluency, and higher odds of WMHs, cerebral infarcts, and hippocampal atrophy. Hippocampal atrophy demonstrated the largest indirect pathway among the evaluated MRI markers, whereas WMHs and infarcts showed smaller indirect pathways. The findings suggest that cumulative modifiable risk burden is associated with poorer brain health and cognitive functioning in later life. Examining risk factors collectively provides a clearer understanding of brain health vulnerability and supports multidomain prevention strategies that target clustered modifiable risks.
