Decoding the Gut-Brain Axis in Alzheimer's Disease: Emerging Perspectives.

Alzheimer's disease (AD) is a leading source of dementia, evidenced by cognitive debility, tau neurofibrillary tangles, and amyloid-β plaques. Recent studies emphasize the gut-brain axis as a vital element in the pathogenesis of Alzheimer's disease, involving microbial, neuronal, immunological, and hormonal mechanisms. The composition of gut microbiota dysbiosis is determined by growth in intestinal barrier permeability and activation of immune cells, which causes impaired function of the blood-brain barrier that stimulates neural injury, neuronal loss, neuroinflammation, and eventually AD.
