Parkinson’s Disease (PD) is a Gut-Brain Axis driven illness.
Research reveals that imbalanced or insufficient probiotic levels promote neuroinflammation and PD development/exacerbation.

Another study reveals that PD is often associated with a “mixed microbial infection”; meaning, the brains of PD patients contain a mixture of fungal and bacterial species associated with promoting brain inflammation and neurodegenerative disease like PD.

Take home: 
As I discuss in chapter 1 of my international best-selling book, there is much more to Parkinson’s Disease development and treatment than focusing only on dopamine.
You must find and address all causes. Many of which originate far from the dopamine receptors in the brain.
