Abstract: 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. Various studies have reported that the gut microbiota plays a crucial role in brain function and changes in individual behavior, as well as in bacterial amyloid formation. Growing experimental and clinical data specify the conspicuous role of intestinal dysbiosis and microbiota- host interactions in AD. The importance of this paper is the focus on the potential association of AD and gut microbiota and also a discussion of the therapeutic modalities of inhibiting gut dysbiosis.
