“Now we were quite confident that gut bacteria regulate, and are even required for, the symptoms of Parkinson’s disease.”
The scientists believe the bacteria are releasing chemicals that over-activate parts of the brain, leading to damage.
The bacteria can break down fibre into short-chain fatty acids. It is thought an imbalance in these chemicals triggers the immune cells in the brain to cause damage.
.. Dr Patrick Lewis, from the University of Reading, said: “This study really does reinforce the idea that examining what goes on in the stomach of people with Parkinson’s could provide really important insights into what happens in disease, and potentially a new area of biology to target in trying to slow down or halt the changes in the brain.”
