Abstract

The notion of immunological pathways playing a role in the etiology of a subset of psychotic disorders has received increased interest in the last decades. One of the findings that has spiked interest herein, is an apparent link between autoimmune diseases and psychotic disorders. This is supported by genetic findings associating immune-related genetic markers with schizophrenia and clinical studies finding increased levels of inflammatory markers in patients with psychosis. Several large-scale epidemiologic studies have found positive associations between autoimmune diseases and psychosis. Particularly, autoimmune diseases as multiple sclerosis and lupus are known to have higher frequencies of neuropsychiatric symptoms, including psychosis, compared to healthy controls. Cross sectional studies have found higher prevalence of psychiatric diagnoses among those with autoimmune diseases, and longitudinal studies have shown bidirectional associations between several autoimmune diseases and increased risks associated with schizophrenia. Moreover, a family history of autoimmune diseases has been shown to be associated with an increased risk of psychotic disorders and vice versa. In this review we will summarize the epidemiologic evidence on associations between autoimmune diseases and psychosis. Possible mechanisms accountable for the association will be discussed, amongst others the probable role of shared genetic risk factors, the impact of infections on both autoimmunity and the development of psychotic disorders, and the potential role of the microbiome. We discuss the findings on and influence of autoantibodies and dysregulation of T- and B-cells in both disease categories, and why further research hereon is needed. In addition to the potential importance of autoimmunity in etiological mechanisms of psychotic disorders, the association also brings important attention to somatic comorbidity in patients with psychotic disorders.

  • Neuropsychiatric conditions such as depression, anxiety, psychosis, and cognitive impairment are often prevalent in patients with chronic kidney disease, non-alcoholic fatty liver disease, and autoimmune disorders.

    “Neuropsychiatric conditions, such as depression, anxiety, psychosis, and cognitive impairment, are often prevalent in patients with chronic kidney disease (CKD), non-alcoholic fatty liver disease (NAFLD), and autoimmune disorders”

    From A Critical Review and Meta-Analysis of Impacts of Per- and Polyfluorinated Substances on the Brain and Behavior (2022) · cites this paper as Jeppesen and Benros, 2019

    The Epidemiological Associations > Lupus section reports depression, anxiety, and psychosis in patients with systemic lupus erythematosus, supporting part of the autoimmune-disorders claim. The passages do not support the claim about chronic kidney disease or non-alcoholic fatty liver disease, or establish cognitive impairment as prevalent across the listed patient groups; searches for those conditions and cognitive impairment found no such evidence in our copy. Page numbers are unavailable. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
