Gut health and central nervous system

Research has associated changes in the gut microbiome with several neurodegenerative and central nervous system diseases, such as Alzheimer's and Parkinson's disease.

For example, it has emerged that patients with Alzheimer’s disease have a distinct microbiome composition and decreased microbial diversity compared to healthy individuals. Other recent studies have associated changes in the gut microbiome with Multiple Sclerosis, Amyloid Lateral Sclerosis and Parkinson’s.

Explore the research articles listed below to learn more about these insights and uncover further links between the gut microbiome and neurodegenerative diseases.
