    Area of Science:

    • Psychiatry
    • Genetics
    • Neurology

    Background:

    • Folie à deux, a rare psychiatric condition, involves shared delusions between individuals.
    • Understanding the familial transmission and subtypes of shared psychotic disorders is crucial for diagnosis and treatment.

    Observation:

    • A case of folie à quatre is presented, involving a proband, his wife, sister, and brother.
    • Three family members exhibited persistent paranoid schizophrenia symptoms.
    • The wife, initially affected by delusions (folie imposée), recovered over time.
    • A coincidental cluster of Huntington's chorea cases was noted in the wife's relatives.

    Findings:

    • The case illustrates multiple categories of folie à deux within a single family unit.
    • Demonstrates the spectrum of shared psychotic disorder, from persistent schizophrenia to transiently imposed delusions.
