Screening for anti-NMDAR Encephalitis in Psychiatry
Anti-NMDAR encephalitis most commonly presents to psychiatric services, so early identification of this disorder is essential. We aim to validate the two screening criteria (Scott et al. and Herken and Pruss) which have been proposed to identify first episode psychosis patients who should have anti-NMDAR antibody testing.
Psychosis associated to CASPR2 autoantibodies and ovarian teratoma: A case report
First report of CASPR2 associated psychosis related to an ovarian teratoma. Prompt reduction of psychotic symptoms after excision of teratoma. The diagnosis of autoimmune psychosis can be made in the presence of autoantibodies in the serum while CSF is unremarkable.
Patients with depressive and psychotic symptoms non-responding to antidepressant and antipsychotic treatment should be screened for neuronal autoantibodies including CASPR2.
Autoimmune psychosis: an international consensus on an approach to the diagnosis and management of psychosis of suspected autoimmune origin
2 years in the making, top experts in the field make a valueable contribution in this work. They briefly review the background, discuss the existing evidence for a form of autoimmune psychosis, and propose a novel, conservative approach to the recognition of possible, probable, and definite autoimmune psychoses for use in psychiatric practice. Investigations required and the appropriate therapeutic approaches, both psychiatric and immunological, for probable and definite cases of autoimmune psychoses are outlined, and discuss the ethical issues posed by this challenging diagnostic category.
Autoimmunity in psychotic disorders. Where we stand, challenges and opportunities
Take home message
- To date, pathogenic autoantibodies targeting neuronal surface antigens are very rare in psychotic disorders without any form of neurological manifestation.
- Awareness from psychiatrist of the existence of symptoms which overlap between autoimmune encephalitis and psychotic disorders is essential to prompt early diagnosis and intervention for cases with an atypical disease course.

A prospective three-year follow up on the clinical significance of anti-neuronal antibodies in acute psychiatric disorders
The clinical significance of anti-neuronal antibodies for psychiatric disorders is controversial. We investigated if a positive anti-neuronal antibody status at admission to acute psychiatric inpatient care was associated with a more severe neuropsychiatric phenotype and more frequent abnormalities during clinical work-up three years later.
