Interventions to Improve Cognitive Outcomes in Older Adults with Traumatic Brain Injury and Association Between Social Determinants of Health and Intervention Effectiveness: A Scoping Review.
Review in Canadian geriatrics journal : CGJ, 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
Background: At least one million Canadians are at risk of experiencing a traumatic brain injury (TBI) in later life, which can lead to cognitive decline. We identified interventions studied to improve cognitive outcomes in older adults with TBI, and examined how social determinants of health (SDoH) may influence their effectiveness. Methods: We followed JBI guidance and searched five electronic databases from inception until March 2023 for studies evaluating the clinical and cost effectiveness, and safety of interventions being studied to improve cognitive outcomes in older adults with TBI. We abstracted SDoH following the PROGRESS-Plus framework. Results: We included 20 studies and 44,462 predominantly men/male (65%) participants with a mean age of 65.9 years; studies reported 51 cognitive outcomes. Three studies reported on race or ethnicity, eight studies reported on education, and no studies differentiated gender from sex. No studies reported on the association between SDoH and intervention effectiveness. We did not identify any economic evaluations. We classified 10 interventions into four categories: non-pharmacologic cognitive strategies (number of studies [n]=16), medications (n=1), non-invasive procedures (n=2), and invasive procedures (n=1). Invasive procedures and non-pharmacologic cognitive strategies had a statistically significant positive effect on cognitive measures in one and seven studies, respectively. Non-invasive procedures (n=2) did not have significant cognitive effects. Use of hypnotics (benzodiazepines and non-benzodiazepines) was significantly associated with a shorter time to incident dementia in one study. Conclusion: Non-pharmacologic cognitive strategies were the most-studied interventions for improving cognitive outcomes in older adults with TBI. Future research should better integrate a health equity lens and standardize outcome measurement.
