Abstract: Alzheimer's disease (AD) is the most prevalent type of dementia, but its etiopathogenesis is
not yet fully understood. Recent preclinical studies and clinical evidence indicate that changes in the
gut microbiome could potentially play a role in the accumulation of amyloid beta. However, the relationship
between gut dysbiosis and AD is still elusive. In this review, the potential impact of the gut
microbiome on AD development and progression is discussed. Pre-clinical and clinical literature exploring
changes in gut microbiome composition is assessed, which can contribute to AD pathology
including increased amyloid beta deposition and cognitive impairment. The gut-brain axis and the
potential involvement of metabolites produced by the gut microbiome in AD are also highlighted.
Furthermore, the potential of antibiotics, prebiotics, probiotics, fecal microbiota transplantation, and
dietary interventions as complementary therapies for the management of AD is summarized. This
review provides valuable insights into potential therapeutic strategies to modulate the gut microbiome
in AD.
