Social connection and cognitive health: A review of concepts, measures, and research priorities.
Review in Alzheimer's & dementia : the journal of the Alzheimer's Association, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Lack of social connection is a major risk factor for Alzheimer's disease and related dementias, on a par with other common risk factors like physical inactivity and smoking. Yet we still know surprisingly little about how social connection affects cognitive health. Our review provides updated guidance for researchers interested in testing new mechanistic models of social connection and cognitive health over the life course. First, we conceptualize social connection and its various components. Second, we provide readers with a supplemental compendium of social connection measures and discuss how to tailor different types of measures to specific research goals. Third, we advance a conceptual model linking social connection to cognitive health across different social, spatial, and temporal contexts, while also considering potential sources of confounding and reciprocal causation. Finally, we outline five priority areas for future research into social connection and cognitive health across the life course.
