Abstract: Alzheimer’s Disease (AD) is a complex neurodegenerative disease that requires interprofessional collaboration. Pharmacological options are currently ineffective, increasing the need for preventative strategies to combat the rise of AD. Considerations of gut-targeted interventions have increased as a key component in the prevention of AD, based on the understanding that the state of the gut microbiome can impact cognitive function through the pathway known as the gut-brain axis.

Methods: This scoping review explored information on the gut-brain axis in persons with AD. A comprehensive search was conducted in November 2023. Forty reviews and 13 human studies were analyzed.

Results: There is an abundance of information supporting the role of the gut-brain axis in the development and prevention of AD. This information is complex and may deter healthcare professionals outside of neuroscience, medicine, and nutrition from engaging in the literature. Further research is needed from within the SLP’s scope of practice.
