The incidence of autoimmune encephalitis increased over time from 0.4/100,000 person-years (1995–2005) to 1.2/100,000 person-years (2006–2015) (p=0.02), attributable to increased recognition of autoantibody-positive cases. The incidence (2.3 vs 0.7/100,000 person-years; p=0.01) and prevalence (38.3 vs 12.9/100,000; p=0.03) of autoimmune encephalitis was higher among African-Americans than Caucasians. Additionally, males had a significantly higher prevalence of autoimmune encephalitis than females (19.0 vs 7.2/100,000, p=0.04). The prevalence of specific neural autoantibody biomarkers among the definite autoimmune encephalitis category was: glutamic acid decarboxylase-65 (GAD65) (1.9/100,000); unclassified neural autoantibody (1.4/100,000); myelin-oligodendrocyte-glycoprotein (MOG) (1.3/100,000); leucine-rich glioma-inactivated-protein-1 (LGI1) (0.7/100,000); collapsin response-mediator protein-5 (CRMP5) (0.7/100,000); N-methyl-D-aspartate-receptor (NMDAR) (0.6/100,000); anti-neuronal nuclear antibody-2 (ANNA-2/anti-Ri) (0.6/100,000) and glial fibrillary acidic protein-α (GFAPα) (0.6/100,000).Conclusions: This study shows that the prevalence and incidence of autoimmune encephalitis is comparable to infectious encephalitis and its recognition is increasing over time.Disclosure: Dr. Dubey has nothing to disclose.
