Is schizophrenia an immunologic receptor disorder?

H H Fudenberg, H D Whitten, E Merler

    Medical Hypotheses
    |September 1, 1983
    PubMed
    Summary

    Schizophrenia may stem from an autoimmune response targeting neurotransmitter receptors, causing fluctuating psychotic symptoms. This model suggests schizophrenia is a syndrome, not a distinct disease, supported by immune dysfunction findings.

    Area of Science:

    • Neuroimmunology
    • Psychiatry
    • Autoimmune Diseases

    Background:

    • Schizophrenia is a complex psychiatric disorder with unclear etiology.
    • Existing research suggests immune system dysfunction in some patients with schizophreniform psychoses.
    • Autoimmune models are established for other receptor-mediated diseases.

    Purpose of the Study:

    • To propose a novel autoimmune etiology for schizophrenia.
    • To present schizophrenia as a syndrome rather than a singular disease.
    • To hypothesize the role of autoantibodies in psychotic symptom fluctuations.

    Main Methods:

    • Literature review of autoimmune receptor diseases.
    • Analysis of emerging evidence on immune dysfunction in schizophrenia.
    • Development of a theoretical model for autoimmune pathogenesis.

    Main Results:

    • Proposed model posits autoantibodies or cell-mediated immunity against neurotransmitter receptors.
    • This autoimmune activity is hypothesized to cause the waxing and waning of psychotic symptoms.
    • The model integrates findings from other autoimmune diseases and immune dysregulation in schizophrenia.

    Conclusions:

    • Schizophrenia may be understood as a syndrome driven by autoimmune processes.
    • Autoantibodies targeting neurotransmitter receptors offer a potential explanation for symptom variability.
    • Further research into neuroinflammation and autoimmunity in schizophrenia is warranted.
