Neurodegenerative diseases such as Parkinson’s could have a direct relationship with the intestine and, therefore, with our gut microbiota as well, says neurologist and leading researcher in the field, Filip Scheperjans.

Most mucosal surfaces of the human body contain an extremely complex ecosystem of microbial organisms. These resident microbes exist in a delicate balance with each other and the human host that is dictated by the specific local environmental factors of each host body site. In health, the many different species that make up the microbiota exist in homeostasis with the host immune system. A dysbiosis of the microbiota shifts the community, which may lead to disease.
