This is going to sound like a joke, but I’m serious: I hope Michael J Fox tries this out and reports back some positive results.

This is a very simple treatment that is universally available, can be done at home, and at the very least is preventative. He is a huge public figure in the Parkinson’s world, and any potential upside to him for this would be enough to get a lot of people to also get the same if they have a risk, or are early-stage.

The article doesn’t go into if this can still help late-stage Patients, but it would track that it could at least stop symptom progression, being a simple vitamin deficiency and all. A more fully formed treatment could also include fecal transplants to replace aged or missing colonies of these gut bacteria if a late-stage progression means these colonies have just died off.

Sadly, since Parkinson’s ultimately is about neuron damage or death, I don’t think any of this is expected to repair any damage already done.
