Emmanuelle Viré, PhD, Institute of Prion Diseases, University College London, London, UK, gives an overview of the presentations given at ARUK 2022 on the role of the gut microbiome in the development of Alzheimer’s disease. This area of research has been expanding in recent years, as more research is carried out into whether altering the gut microbiome could prevent, halt, or even reverse the symptoms of Alzheimer’s disease.
