Microbes Tickling Your Tummy: the Importance of the Gut-Brain Axis in Parkinson’s Disease

Purpose of ReviewPatients suffering from Parkinson’s disease (PD) are known to experience gastrointestinal dysfunction that might precede the onset of motor symptoms by several years. Evidence suggests an important role of the gut-brain axis in PD pathogenesis. These interactions might be essentially influenced by the gut microbiota. Here, we review recent findings supporting that changes in the gut microbiota composition might be a trigger for inflammation contributing to neurodegeneration in PD.
