Diagnostic Utility of CSF Alpha-Synuclein
This observational study investigated whether the cerebrospinal fluid (CSF) α-synuclein (α-syn) real-time quaking-induced conversion (RT-QuIC) assay, applied to 289 CSF samples, accurately identified patients with mild cognitive impairment (MCI) caused by probable Lewy body (LB) disease. RT-QuIC identified patients with MCI-LB against cognitively unimpaired controls with 95% sensitivity, 97% specificity, and 96% accuracy and showed 98% specificity in neuropathologic controls, indicating that CSF α-syn RT-QuIC is a robust biomarker for prodromal dementia with Lewy bodies.

Thinking Outside of the ‘Alpha-Synuclein Box’: A Critical Role of Tau in Lewy Body Disorders
Neocortical tau pathology was associated with worse antemortem cognition in this large study of Parkinson’s disease dementia and dementia with Lewy bodies. Regional brain variations correlated with specific cognitive domains.

Plasma α-Synuclein Is a Leading Candidate Biomarker in Parkinson’s Disease
In this cross-sectional study, plasma alpha-synuclein levels were higher in individuals with Parkinson’s disease than controls, and correlated with cognitive decline.
