Bacteria in the gut could be linked to Parkinson’s, research finds

Animal experiments by scientists in California has successfully linked bacteria in the gut to Parkinson’s disease.


Parkinson’s disease is when an individual’s specific nerve cells in the brain don’t work properly, this is because the nerve cells in question create neurotransmitter, Dopamine. Dopamine transports signals to the section of your brain that influences motion. A Parkinson’s sufferer’s nerve cells that manage movement are damaged, meaning they can no longer move with ease. The disease has no cure and slowly worsens with time.

The recent research is a step in the right direction for those with Parkinson’s. The scientific process looked at mice with Parkinson’s and healthy mice. The scientists found that only the mice with stomach bacteria began to experience Parkinson’s symptoms.

According to the summary of the Scientist’s entry in Science Journal, Cell ‘microbmicrobial re-colonization promotes, pathophysiology in adult animals, suggesting that postnatal signaling between the gut and the brain modulates disease’. 


Director of Research at Parkinson’s UK, Dr Arthur Roach, says:

“The greatest need in Parkinson’s research is to develop treatments that can stop or slow down the processes that first lead to the condition, something no current treatments can do. This work opens an exciting new avenue of study on the gut-brain connection in Parkinson’s. There are still many questions to answer but we hope this will trigger more research that will ultimately revolutionise treatment options for Parkinson’s.”
