    Area of Science:

    • Neuroscience
    • Psychiatry
    • Human Behavior

    Background:

    • Laterality disturbances have been anecdotally linked to schizophrenia.
    • Previous research has explored potential correlations between schizophrenia and atypical hand preference.

    Purpose of the Study:

    • To investigate hand preference patterns in individuals with schizophrenia.
    • To determine if schizophrenia is associated with laterality disturbances.

    Main Methods:

    • A comparative study involving 26 schizophrenic patients, 21 non-schizophrenic patients, and 18 staff controls.
    • Participants were within specific age ranges (40-55 yr. for patients, 25-40 yr. for controls).
    • Hand preference was assessed through direct questioning within a public psychiatric hospital setting.

    Main Results:

    • Schizophrenic patients exhibited slightly more confusion regarding hand preference.
    • No significant differences in overall hand preference patterns were observed between schizophrenic patients, non-schizophrenic patients, and control groups.
    • The findings did not support the inclusion of schizophrenics among groups with identified laterality disturbances.

    Conclusions:

    • Schizophrenia, in this study cohort, was not found to be associated with significant laterality disturbances.
    • The observed slight confusion in hand preference among schizophrenics warrants further investigation but does not confirm a link to atypical lateralization.
