What is the role of the gut microbiome in developing Parkinsons disease
In recent years, an important Parkinson's disease (PD) research focus has been on gut-related pathology, pathophysiology, and symptoms. In a contribution in the current issue of the Journal of Parkinson's Disease, researchers review some of the latest studies linking gut microbiota to PD.
Gastrointestinal dysfunction, in particular constipation, affects up to 80% of PD patients and idiopathic constipation is one of the strongest risk-factors for PD. Lifestyle factors such as smoking and coffee consumption, as well as blood urate levels, have been associated with a decreased PD risk. These factors may also be influenced by the bacteria living in the human gut mediating the effects of various chemicals and nutrients on disease processes.
