Autoimmune encephalitis (AE) is a potentially treatable cause of rapidly progressive dementia (RPD) that may mimic Creutzfeldt-Jakob disease (CJD). Alzheimer disease (AD) cerebrospinal fluid (CSF) biomarkers may discriminate CJD from AD, but utility in discriminating CJD and AE is unclear. This study compared AD CSF biomarkers in CJD and AE. Patients with probable or definite CJD and probable or definite AE who underwent Roche Elecsys AD CSF biomarker testing at Mayo Clinic from March 2020 through April 2021 were included. Total-tau (t-tau), phosphorylated181 tau (p-tau), and amyloid-β42 (Aβ42) levels were compared. Of 11 CJD cases, 4 were autopsy proven; the rest had positive real-time quaking-induced conversion (RT-QuIC) testing. Disease-associated autoantibodies were detected in 8/15 cases of AE: LGI1 and NIF (2 cases each), and NMDAR, CASPR2, DPPX, and IgLON5. T-tau provided excellent discrimination between CJD and AE in a univariate model (OR 1.46 per 100pg/mL, CI 1.17-2.11, p <.05, c=0.93). T-tau was elevated in 91% of CJD cases (median >1300, range 236 - >1300 pg/mL), of which 55% were above the limit of assay measurement (>1300 pg/mL). T-tau was elevated in 20% of AE cases (median 158, range 80->1300 pg/mL). T-tau was greater in CJD than AE. Given that Aβ42 and p-tau were comparable, the ratio differences were likely driven by elevated t-tau in CJD. This study supports the role for AD biomarker testing in patients with RPD. Creutzfeldt-Jakob disease has greater mean cerebrospinal fluid t-tau, t-tau/p-tau ratio, and t-tau/Aβ42 ratio than autoimmune encephalitis
