Cocaine psychoses: a continuum model.

R M Post

    The American Journal of Psychiatry

    Summary
    This summary is machine-generated.

    Cocaine use can lead to a spectrum of psychiatric issues, from mood changes to psychosis. This suggests a potential continuum in mental health disorders linked to neurotransmitter alterations.

    Area of Science:

    • Neuroscience
    • Psychiatry
    • Pharmacology

    Background:

    • Cocaine use is associated with diverse psychiatric manifestations.
    • Previous models often linked single illnesses to single neurotransmitters.

    Purpose of the Study:

    • To describe the progression of clinical syndromes associated with cocaine use.
    • To explore the implications of drug-induced psychosis for understanding endogenous psychoses.
    • To propose a unified model for psychiatric syndromes involving neurotransmitter alternations.

    Main Methods:

    • Clinical observation and description of cocaine-induced syndromes.
    • Analysis of the relationship between dosage, chronicity, and individual predispositions.
    • Comparative analysis with existing models of psychiatric disorders.

    Main Results:

    • An orderly progression of syndromes (euphoria, dysphoria, paranoid psychosis) was observed with cocaine use.
    • These affective alternations and schizophreniform psychosis suggest a continuum of psychiatric conditions.
    • Neurotransmitter alternations may underlie multiple psychiatric syndromes, challenging "one illness, one transmitter" paradigms.

    Conclusions:

    • Cocaine-induced psychiatric syndromes may represent a continuum relevant to endogenous psychoses.
    • A single neurotransmitter system could be implicated in a range of psychiatric manifestations.
    • This challenges traditional, disease-specific etiological models in psychiatry.
