Subjects with detectable Saccharomyces cerevisiae in the gut microbiota show deficits in attention and executive function

Abstract

There is progressive awareness that gut microbiota composition and function are associated with cognitive traits [1] through a putative gut microbiota– brain axis. In addition to bacteria, the human intestine is home to a wide range of fungal species, forming an ecological community that contributes to normal physiology and disease susceptibility [2]. There is some evidence that the brain of elderly persons with Alzheimer’s disease contains both fungi and bacteria [3].
