Saliva gland test may diagnose early Parkinson’s disease

I have read about a new diagnosis for Parkinson’s disease through saliva gland testing. Presently diagnosis of Parkinson’s disease is conducted through medical history, observation of symptoms, ruling out other conditions, and neurological examinations.

I hope this new diagnosis - saliva gland testing offer the accuracy doctors need for the diagnosis -

Get checked for serine deficiency.


The neuro toxin BMAA has been confirmed in AD and PD brain samples. It's also linked to PSP through hair samples. They are currently doing trials with ALS patients.

Bmaa is similar structurally to l-serine, an amino acid. Serine is used in the process of manufacturing membranes.

They are talking about serine being a preventative treatment. But their research to date only confirms the link through animal studies. Their ALS trials passed safety phase one and are onto phase two. But they are advising against taking serine as the haven't studied for adverse effects fully.

Press releases

All current trials with l-serine

Serine deficiency is associated with the CBS gene. CBS snps can complicate the approach to supplementation and result in high sulfur. Do not supplement serine without working with a qualified professional who can screen your genetics. You can do more harm than good. You might try a low sulphur/low protein diet to reduce sulphur. Or consider using yucca powder to help break down protein when you do eat protein.

Yeah, I've been moving away from the idea of treating by giving him serine etc. Im looking at whey protein as it provides the building blocks for the body to do it naturally. But you're saying less protein...

Im a layman learning as I go but I'll listen to what anyone has to say, however, I have to ask, do you have a medical background?

I've also bee looking at a getting his genetics screened.

Thanks for the heads up though bud. Feel free to comment on my thread in the PSPA section of the site with any insight you may have.



I do not have a medical background. I have been studying for the last 14 years since my husband was diagnosed many fields of science. For years in Parkinson's doctors have often recommended a low protein diet or not eating protein near times when medicine is taken. I suspect that in addition to the CBS gene there are potential issues with the PAH gene in some with PD as well as a number of other nutrient processing genes. But these are just theories that I am working on. There is a lot of material on the CBS gene if you are interested in searching and reading. COMT is another one.

Interesting... a relatively easy way to confirm a PD diagnosis would be great if it ultimately proves accurate :)


What is the test looking for? Ammonia?
