    Area of Science:

    • Psychiatry
    • Mental Health
    • Psychopathology

    Background:

    • The current definition of Folie à deux in the Diagnostic and Statistical Manual of Mental Disorders, Third Edition (DSM-III) is considered misleading.
    • Folie à deux is not recognized as an independent psychiatric disorder.
    • It is understood as a shared phenomenon within the context of existing delusional psychiatric illnesses.

    Purpose of the Study:

    • To critically evaluate the existing definition of Folie à deux.
    • To reframe Folie à deux as a phenomenon rather than a distinct disorder.
    • To propose an updated nomenclature for shared paranoid disorders.

    Main Methods:

    • Literature review of psychiatric classifications and case studies.
    • Analysis of the conceptual underpinnings of shared delusional experiences.
    • Comparative analysis of diagnostic criteria.

    Main Results:

    • Folie à deux is a symptom or manifestation of underlying delusional disorders.
    • Two primary types of this shared phenomenon have been identified.
    • The existing nomenclature requires revision to accurately reflect its nature.

    Conclusions:

    • The concept of Folie à deux should be understood as a shared psychotic experience linked to primary delusional disorders.
    • An updated classification system is necessary for precise diagnosis and research.
    • Clarifying the nature of Folie à deux improves understanding of delusional psychopathology.
