Effects and Mechanisms of Probiotics, Prebiotics, Synbiotics, and Postbiotics for the Prevention and Management of Alzheimer's Disease: A Narrative Review.
Review in Antioxidants (Basel, Switzerland), 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
Alzheimer's disease (AD) is a rapidly escalating global health crisis with limited effective treatments. Emerging research underscores the pivotal role of the microbiota-gut-brain axis in AD pathogenesis, prompting the exploration into gut microbiota-targeted interventions. This narrative review aimed to comprehensively synthesize the latest epidemiological, experimental, and clinical evidence regarding the effects and mechanisms of probiotics, prebiotics, synbiotics, and postbiotics (PPSPs) in AD prevention and management. We conducted a narrative review of relevant literature from the Web of Science and PubMed databases. The search focused on articles published within the last 5 years using keywords such as "Alzheimer's disease", "AD", "gut-brain axis", "gut microbiota", "probiotics", "prebiotics", "synbiotics", and "postbiotics". The findings suggest that PPSPs mitigate AD pathology and improve cognitive performance by modulating gut microbiota, strengthening intestinal barrier integrity, decreasing amyloid-beta (Aβ) deposition and tau hyperphosphorylation, reducing neuroinflammation and oxidative stress, regulating neurotransmitter metabolism, and promoting synaptic plasticity. Some studies also report varied outcomes, attributable to factors like strain specificity, dosage, intervention duration, patient heterogeneity, and methodological differences. In conclusion, targeting the microbiota-gut-brain axis with PPSPs offers a promising, mechanism-based strategy for AD, though further research is essential to optimize specific interventions for clinical application.
