Our results do not support the hypothesis of a link between essential tremor and Parkinson's disease. However, it appears that ET patients have a small degree of striatal dopaminergic degeneration. If this is due to alterations in the nigrostriatl pathway or of other origin it is not clear. Follow-up studies of essential tremor patients are warranted to assess progression of disease and to understand better the possible cause for striatal dopaminergic degeneration.
Conclusively, the correlation between elevated levels of tau proteins and hypoperfusion in SPECT in AD patients therefore cannot improve the specificity of tests in AD and this means that the determination of CSF tau proteins levels is not a specific diagnostic test for AD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
