Brain disconnection, schizophrenia, and paranoia.

P A Magaro, J Page

    The Journal of Nervous and Mental Disease
    |March 1, 1983
    PubMed
    Summary

    Schizophrenia research reveals nonparanoid patients exhibit left hemisphere deficits, impacting cognitive tasks. Paranoid schizophrenia patients show no such hemisphere-specific cognitive impairments.

    Area of Science:

    • Neuroscience
    • Psychiatry
    • Cognitive Psychology

    Background:

    • Schizophrenic cognition theories include lateralized hemisphere deficits and interhemispheric dysfunction.
    • Previous research suggested interhemispheric deficits in schizophrenia based on visual stimulus matching tasks.

    Purpose of the Study:

    • To investigate hemispheric and interhemispheric deficits in schizophrenic cognition.
    • To differentiate cognitive deficits between paranoid and nonparanoid schizophrenia subtypes.

    Main Methods:

    • Expanded upon Beaumont and Dimond's (1973) study on visual stimulus matching across hemispheres.
    • Compared performance of paranoid schizophrenics, nonparanoid schizophrenics, and control groups.

    Main Results:

    • Nonparanoid schizophrenics demonstrated significant deficits in left hemisphere processing.
    • Nonparanoid schizophrenics also showed interhemispheric matching problems, attributed to left hemisphere impairment.
    • Paranoid schizophrenics performed comparably to controls across all hemisphere conditions.

    Conclusions:

    • Findings do not support a general interhemisphere transfer deficit in schizophrenia.
    • Results suggest nonparanoid schizophrenia is characterized by left hemisphere processing deficits, potentially related to serial processing impairments.
