We describe the epidemiological and socioeconomic characteristics of patients with anti-NMDAR encephalitis, including age of onset, presence of antecedent infections or triggers, race and ethnicity, sex, zip code, Gini index, Health Professional Shortage Area (HPSA) designations, duration from symptom onset to diagnosis, insurance type, primary language, and outcome by modified Rankin Score (mRS). We will conduct sensitive analysis on identifying any socioeconomic variables as covariance with the severity of anti-NMDAR encephalitis.

In this cohort, anti-NMDAR encephalitis outcomes were encouraging in the majority of patients. Recognition of specific epidemiologic and demographic related to social determinants of health variables placing anti-NMDAR encephalitis patients at risk for delays in diagnosis and/or underutilization of medical care will benefit this patient population.
