    Longitudinal Disability, Cognitive Impairment, and Mood Symptoms in Patients With Anti-NMDA Receptor Encephalitis · 2024 · DOI

  • Population-based epidemiologic studies are lacking because of both poor patient capture and the lack of standardized diagnostic criteria.

    Population-Based Study of the Epidemiology of Stiff Person Syndrome in a Large Colorado-Based Health System · 2024 · DOI

    Cardiopulmonary Coupling Spectrogram as an Ambulatory Method for Assessing Sleep Disorders in Patients With Autoimmune Encephalitis · 2024 · DOI

  • BACKGROUND: Despite comprising one-third of AE cases, antibody-negative cases lacking typical AE-defining features are understudied.

    A Case of Septin-7 Antibody-associated Encephalitis Associated with Seizures and Squamous Cell Lung Carcinoma · 2024 · DOI

  • The diagnosis of autoimmune limbic encephalitis can be challenging due to normal investigative findings. There is a need for better understanding of the clinical picture of autoimmune limbic encephalitis.

    Uncommon presentation of autoimmune limbic encephalitis: a case report · 2026 · DOI

  • The association between SPR and autoimmune diabetes is not well understood. The diagnosis of SPR is often delayed due to its rarity and similarity to other neurological conditions.

  • Further studies are needed to understand the immunological links underlying the comorbidity of autoimmune nodopathy with Sjögren’s disease and nephrotic syndrome. The effectiveness of rituximab in treating AN associated with Sjögren’s disease and nephrotic syndrome needs to be investigated.

    Autoimmune nodopathy associated with Sjögren’s disease and nephrotic syndrome: a case report and literature review · 2026 · DOI

  • The co-occurrence of autoimmune nodopathy with Sjögren’s disease and nephrotic syndrome is an exceptionally rare comorbid phenotype. The immunological links underlying this comorbidity are not well understood.

    Autoimmune nodopathy associated with Sjögren’s disease and nephrotic syndrome: a case report and literature review · 2026 · DOI

  • The absence of definitive biomarkers for AE makes diagnosis challenging. The heterogeneity of clinical manifestations of AE complicates diagnosis.

    Diagnostic pitfalls in autoimmune encephalitis: lessons from an antibody-negative case · 2026 · DOI

  • Autoimmune encephalitis is a complex and heterogeneous disorder. Seizures in this population can be difficult to control. There is a need for effective and safe treatment options.

    Perampanel use in pediatric autoimmune encephalitis-related seizures and epilepsy: a retrospective case series · 2026 · DOI

  • Limited data is available on the use of antiseizure medications in pediatric patients with autoimmune encephalitis-related seizures and epilepsy. There is a need for further studies to investigate the efficacy and safety of perampanel in this population.

    Perampanel use in pediatric autoimmune encephalitis-related seizures and epilepsy: a retrospective case series · 2026 · DOI

  • There is a lack of awareness of oneiric stupor as a rare manifestation of LGI1 encephalitis. The diagnosis of oneiric stupor can be challenging due to its rarity and overlap with other conditions.

    Oneiric stupor as a clinical manifestation of LGI1 antibody-associated autoimmune encephalitis: a case report · 2026 · DOI

  • Oneiric stupor, characterized by stereotyped gestures mimicking everyday activities, is a core manifestation of agrypnia excitata but has only rarely been reported in association with LGI1 encephalitis.

    Oneiric stupor as a clinical manifestation of LGI1 antibody-associated autoimmune encephalitis: a case report · 2026 · DOI

  • Reactive astrogliosis is a complex process. [18F]F-DED PET imaging has a limited scanning time.

    Feasibility of short imaging protocols for [18F]fluordeprenyl-D2 PET in autoimmune encephalitis and multiple system atrophy · 2026 · DOI
