Diagnostic and prognostic performance of CSF α‐synuclein in prion disease in the context of rapidly progressive dementia

Surrogate cerebrospinal fluid (CSF) biomarkers of neurodegeneration still have a central role in the first‐line screening of patients with suspected Creutzfeldt‐Jakob disease (CJD). Recently, CSF α‐synuclein, a marker of synaptic damage, showed a close to optimal performance in distinguishing between CJD and other neurodegenerative dementias.
