Biochemistry and the schizophrenias.

J R Smythies

    Southern Medical Journal
    |October 1, 1979
    PubMed
    Summary

    This study identifies dimethyltryptamine (DMT), an endogenous hallucinogen, in human samples. Elevated DMT levels are linked to schizophrenia and liver disease, suggesting its role in neuroregulation.

    Area of Science:

    • Neuroscience
    • Psychiatry
    • Biochemistry

    Background:

    • Schizophrenia is complex, with the dopamine hypothesis being a prominent theory.
    • The transmethylation hypothesis also offers insights into schizophrenia's pathophysiology.
    • Endogenous psychoactive substances are increasingly recognized for their potential roles in mental health.

    Purpose of the Study:

    • To review the current understanding of schizophrenia hypotheses.
    • To present data on the identification and measurement of dimethyltryptamine (DMT) in humans.
    • To explore the potential role of DMT as a neuroregulatory agent.

    Main Methods:

    • Review of existing literature on schizophrenia hypotheses.
    • Definitive identification of dimethyltryptamine (DMT) using analytical techniques.
    • Measurement of DMT levels in human cerebrospinal fluid and urine samples.

    Main Results:

    • Dimethyltryptamine (DMT) was definitively identified and measured in human cerebrospinal fluid and urine.
    • Elevated DMT levels were observed in some individuals with schizophrenia.
    • Increased DMT levels were also found in patients with liver disease.

    Conclusions:

    • DMT may function as a normal neuroregulatory agent in the human body.
    • DMT levels appear to be responsive to physiological stressors and emotional states.
    • These findings offer a new perspective on the biological underpinnings of schizophrenia and other conditions.
