Interesting article about lithium and its therapeutic uses for improving all things cognitive, including neuron protection. The article fails to mention, though, the readily available lithium orotate that is a safer form. You can get it at the vitamin shoppe and it is very inexpensive. John Gray, author and nutritionist recommends taking it on a regular basis, as it is non toxic.

i always take these claims with a grain of salt. lithium might be good for your neuron's health but as far as pd is concerned, do people in who drink water with lithium in it have a lower incidence of pd?

The more relevant question might be "does lithium help pwp parkinson's with their symptoms while offering neuroprotection, elevated mood, enhanced memory and possibly other benefits", yes the data seems to support its use.
So here is some more science to make a more educated opinion.

again, the study was on mice. why don't you contact the researcher and see if she is trying to get funding for a trial? the article mentions trying to get funding for a PHASE2A trial? couldn't find a phase1 trial.

seems like it would be easy to find people with pd taking valium and see if they progressed more slowly.

are you going to supplement lithium?

Yes, I am supplementing with lithium orotate, which I believe is safer and available at The Vitamin Shoppe and on line. I will let you know if there is any improvement.

Possible mechanisms surrounding lithium’s cognitive support include its ability to maintain BDNF levels—the crucial neurotropic product recently found severely depleted in CFS. A cohort of Alzheimer’s patients were given lithium over a 10-week period. At the end of the study, participants had significant increases in BDNF in serum and in the brain.

Lithium is a key cofactor in the methylation cycle. Not only does it help transport B12, it also is required for function of the MTR (methionine synthase) enzyme, which recycles homocysteine to methionine. Dr. Yasko believes that in order to maintain healthy B12 levels, lithium levels must also be considered. With increasing loads of B12 such as via intramuscular injection, lithium may become further depleted (6).
