Although there has been some preliminary speculation that lithium may slow certain neurodegenerative deseases, there is no long term data to support its use. Lithium has shown certain neuroprotective properties in short term trials, but I know of none which suggest it actually works to treat or supress the progression of either disease.

Lithium requires regular >check-up, especially at older ages.Lithium use, as well as SSRI use has been associated with later onset of Parkinsons desease. Although, the counterargument is that mood disorders are a risk factor for Parkinsons and not the treatement.
This being said, lithium is actually antidopaminergic. It interacts with dopaminergic pathways via its effects on 5-ht1b receptors.
While this is not proof that it causes parkonsons, it has been associated with onset of parkionsons in a few studies."1: Int Clin Psychopharmacol. 1994 Summer;9(2):127-9. Links
Chronic lithium neurotoxicity presenting as Parkinson's disease.This is just one case. It doesn't proove anything either way.
