This fascinating angle on Parkinson’s comes at an exciting time for gut-brain research on neurological problems. The probiotic L Reuteri has just been shown to strengthen the feedback loops between the levels of the dopamine neurotransmitter and the oxytocin hormone, via the vagus nerve, in recent research by Costa-Mattioli (who stumbled upon it looking for treatments for autism, which is known to correlate with gut issues). Perhaps with CRISPR we are open to engineering new probiotics which can more precisely target these gut-related conditions?
Interesting seeing this here, my grandfather with Parkinson's recently had an abscess near his stomach area burst, and for some reason the severity of his Parkinsons symptoms declined soon after.
Funny how plainly strong the connection between your brain and your gut is (feeling butterflies or distress when you are anxious) yet it hasn’t really been strongly investigated for diseases.
