We compared the epidemiology of autoimmune and infectious encephalitis cases in Tel-Aviv Sourasky Medical Center (TASMC) between 2010 and 2020.<h4>Methods</h4>All encephalitis cases, aged 18 and above, admitted to TASMC between the years 2010 and 2020 were reviewed for demographic, clinical, laboratory, and imaging data and categorized based on etiology.<h4>Results</h4>Two hundred and twenty-five patients with encephalitis were identified. The most common identifiable cause was viral (42%), followed by autoimmune encephalitis (35%), bacterial (18%), and fungal/parasitic (5%). The incidence of AIE cases out of the yearly admitted cases increased substantially, fromAnnals of clinical and translational neurology2337-2349https://www.ebi.ac.uk/biostudies/studies/S-EPMC11537142biostudies-literatureEpidemiology of autoimmune encephalitis and comparison to infectious causes-Experience from a tertiary center.PMC11537142Levinson TMaayan Eshed GMoreno IAshkenazi AMina YCohen-Poradosu RDekel MParan YSegal YRotschild OHalutz OAizenstein OAlcalay YGadoth AfalseEpidemiology of autoimmune encephalitis and comparison to infectious causes-Experience from a tertiary center.<h4>Objectives</h4>The incidence of autoimmune encephalitis (AIE) has risen in the last decade, yet recent studies are lacking.
