In a second cohort where more in-depth clinical characterization could be performed, adults with encephalitis from 2 tertiary hospitals were evaluated using the same questionnaires. Patients' characteristics were retrospectively captured.Results In the first cohort (mean [SD] age; 43 [16] years, 220 [65%] female), 220 of 338 participants (65%) reported fatigue, 175 of 307 (57%) depression, and 211 of 285 (74%) poor sleep quality. In the second cohort (48 [19] years; 43 [50%] women), 42 of 69 participants (61%) reported fatigue, whereas 23 of 68 (34%) reported depression and 44 of 66 (67%) poor sleep quality, despite more than 80% having “good” modified Rankin scale (mRS) scores (0–2). Individuals with anti-NMDA receptor encephalitis reported lower fatigue scores than those with other autoimmune encephalitis types. In a multivariate analysis examining factors at discharge that might predict fatigue scores, only anti-NMDA receptor encephalitis was a (negative) predictor of fatigue and remained so when potential confounders were included.Discussion The impact of fatigue after autoimmune encephalitis is prominent and not fully accounted for by depression or sleep quality, nor adequately captured by mRS scores for disability. Fatigue is pervasive across autoimmune encephalitis, although lower scores are reported in anti-NMDA receptor encephalitis. Fatigue should be screened routinely, considered as an outcome measure in clinical trials, and further studied from a mechanistic standpoint.AE=adverse event; BDI-Fast Screen=Beck Depression Inventory-Fast Screen; CASE=clinical assessment scale in AE; ICU=intensive care unit; ISMMS=Icahn School of Medicine at Mount Sinai; mRS=modified Rankin scale; MFIS=Modified Fatigue Impact Scale; PPHS=Program for the Protection of Human Subjects; PSQI=Pittsburgh Sleep Quality Index; SREAT=steroid-responsive encephalopathy associated with autoimmune thyroiditis
