Pathologically, it is characterized by abnormally elevated levels of amyloid-\u03b2 (A\u03b2) deposition and tau phosphorylation. Given the rapid rate of population aging, many scientists are investigating AD, focusing on its pathogenic mechanisms and potential treatments. Unfortunately, to date, no highly effective therapeutic strategies have emerged. Intriguingly, multiple studies have revealed alterations in the gut microbiome of individuals with AD, suggesting it may serve as a novel avenue for investigating AD pathogenesis.\n                    <jats:italic>Bifidobacterium<\/jats:italic>\n                    , a pivotal probiotic in the gastrointestinal tract, is crucial in upholding the equilibrium of gut flora.

However, current research on the mechanisms through which Bifidobacteria can alleviate AD is limited, warranting further investigation. This review examines Bifidobacterial alterations in Alzheimer\u2019s disease patients and the underlying mechanisms, with the aim of evaluating their potential as a therapeutic strategy for Alzheimer\u2019s disease.\n
