Current study: Intestinal inflammation again linked to Alzheimer's disease. As part of the study, researchers at the University of Wisconsin analyzed stool samples from a total of 125 people for fecal calprotectin.
This protein indicates the presence of so-called neutrophils in the intestinal lining. These are in turn related to inflammation. Alzheimer's patients had increased levels of inflammation in the intestines compared to controls. This could be because changes in the microbiome cause system-wide inflammation, according to Margo Heston.
