简要总结
The objective of the study is to highlight a modification of the composition of the intestinal microbiota associated with the diagnosis of Alzheimer's disease and its most unfavorable form, Rapid Cognitive Decline (DCR). This identification could lead to diagnostic strategies based on the analysis of the intestinal microbiome, and preventive and curative treatments, based on the modulation of intestinal microbiota
