Microbiome‐Phytochemical Crosstalk Along the Gut‐Brain Axis in Alzheimer and Parkinson's Disease

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
Phytochemicals remodel the gut microbiota by enriching beneficial bacteria and microbial metabolites while suppressing dysbiosis and inflammation. Through modulation of the gut–brain axis, they restore intestinal barrier integrity, regulate neuroimmune and neuroprotective signaling pathways, reduce amyloid‐β, tau, and α‐synuclein pathology, and ...
