Longer-term effects and underlying mechanisms of dietary intervention strategies on cognitive performance in adults with cognitive impairment.
Review in Current opinion in clinical nutrition and metabolic care, 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
purpose of reviewAs global life expectancy increases, age-related neurodegenerative conditions such as dementia impose an increasing public health and socioeconomic burden. Maintaining a healthy lifestyle, particularly through a healthy diet, may reduce cognitive decline and support cognitive performance in aging populations. Despite increasing interest in dietary interventions as a strategy to enhance cognitive performance, research findings remain inconclusive. This narrative review aims to synthesize evidence on the longer-term effects (published February 2023-October 2024) and underlying mechanisms of dietary intervention strategies on cognitive performance in adults with preexisting cognitive impairment. RECENT
findingsRecent evidence from randomized controlled trials suggests that both single- and multifactor dietary interventions may improve one or more cognitive domains in aging adults with preexisting cognitive impairment. However, variability in intervention types, durations, and participant characteristics limits the ability to draw definitive conclusions. SUMMARY: This review highlights the potential benefits of longer-term dietary interventions on cognitive performance in adults with cognitive impairment. It further integrates emerging mechanistic insights, suggesting that specific dietary components may exert neuroprotective effects primarily by reducing oxidative stress and neuroinflammation, and by enhancing brain vascular function. These mechanisms may promote neuroplasticity through the modulation of neurotrophic signaling pathways. Future research should focus on replicating these findings to validate their efficacy and the underlying mechanisms involved. This is essential for integrating dietary approaches into evidence-based guidelines for promoting long-term cognitive health.
