Forever chemicals, the microbiome, and brain health: towards therapeutics.
Level 5 - mechanism / opinion, no new human data
Narrative review proposing a mechanistic framework without original human data.
PubMed 42498611 · doi:10.1016/j.tips.2026.06.010
What was done
Narrative synthesis and conceptual framework examining the relationship between per- and polyfluoroalkyl substances (PFAS) exposure, gut microbiota remodeling, and brain health, proposing the integration of microbiome endpoints into toxicological research.
What was found
The abstract reports no quantitative data or specific numerical measurements. It describes conceptual mechanisms whereby PFAS-induced alterations in gut microbiota diversity, taxonomy, and metabolic configuration disrupt gut-brain signaling and contribute to neurodevelopmental, neurodegenerative, and neurological disorders.
Why it matters
It highlights the gut-brain axis as a potential mechanistic mediator of PFAS neurotoxicity and suggests targeting the microbiome for therapeutic intervention.
Limits
This is a narrative review with no primary empirical data, clinical trial outcomes, or systematic review methodology reported in the abstract. Evidence is limited to conceptual and mechanistic hypotheses.
