Capgras syndrome-a biochemical marker?

J L Sullivan, J O Cavenar, A A Maltbie

    The Journal of Nervous and Mental Disease
    |April 1, 1978

    Summary
    This summary is machine-generated.

    Researchers report reduced platelet monoamine oxidase (MAO) activity in two Capgras syndrome cases. This biochemical abnormality may indicate a distinct group of behavioral disorders.

    Area of Science:

    • Neuroscience
    • Biochemistry
    • Psychiatry

    Background:

    • Capgras syndrome is a rare psychiatric disorder.
    • The underlying neurobiology remains poorly understood.

    Observation:

    • Two patients with Capgras syndrome were studied.
    • Platelet monoamine oxidase (MAO) activity was measured.

    Findings:

    • Significantly reduced platelet MAO activity was observed in both Capgras syndrome cases.
    • This is the first documented biochemical abnormality linked to Capgras syndrome.

    Implications:

    • Reduced platelet MAO activity may serve as a biomarker for Capgras syndrome.
    • Patients with Capgras syndrome might represent a distinct behavioral disorder group.
