ABSTRACT
(1) Background:
Alpha-synuclein (α-syn) is a presynaptic neuronal protein that regulates several neuronal functions. In recent decades, the role of α-syn as a biomarker of neurodegenerative diseases has been explored, especially in synucleinopathies. However, only a few studies have assessed its role as biomarker in other neurological disorders. The aim of the study was to evaluate cerebrospinal fluid (CSF) α-syn levels in several neurological disorders; (2)Methods:
We measured CSF α-syn levels by a commercial ELISA kit in 158 patients classified in the following group controls, Alzheimer's Disease (AD), cerebrovascular diseases, inflammatory central nervous system diseases, other neurological diseases, Parkinson's Disease (PD), and peripheral neuropathy; (3)Results:
Patients with PD showed the lowest and patients with AD the highest levels of CSF α-syn (1372 vs. 2912 pg/mL, respectively, p < 0.001). In AD patients, α-syn levels were significantly associated with tau proteins; (4)Conclusions:
α-syn could represent a biomarker of neurodegenerative diseases.
