Motor abilities after frontal leukotomy.

D F Benson, D T Stuss

    Neurology
    |December 1, 1982
    PubMed
    Summary
    This summary is machine-generated.

    Bilateral frontal leukotomy did not significantly impact motor function. Schizophrenia severity, not lesion size, affected motor test results, indicating orbitofrontal lesions don't impair motor skills.

    Area of Science:

    • Neurology
    • Neurosurgery
    • Psychiatry

    Background:

    • Frontal leukotomy, a psychosurgical procedure, involves altering brain connections.
    • Understanding the impact of such procedures on cognitive and motor functions is crucial.

    Purpose of the Study:

    • To assess the effects of bilateral frontal leukotomy on motor function.
    • To determine the influence of lesion size and schizophrenia severity on motor performance.

    Main Methods:

    • Neurologic examinations, tests of praxis, and neuropsychological tests were administered.
    • Five subject groups were used: post-leukotomy schizophrenic patients (three recovery degrees) and two non-leukotomized control groups.
    • Controls accounted for schizophrenia, age, and education effects.

    Main Results:

    • The extent of bifrontal damage did not significantly correlate with motor test performance.
    • Schizophrenia severity was a significant factor influencing motor test outcomes.
    • Bilateral orbitofrontal white matter lesions, as assessed, did not impair motor competency.

    Conclusions:

    • Motor function is not significantly disturbed by bilateral frontal leukotomy.
    • Schizophrenia's severity plays a more critical role in motor deficits than the extent of frontal lesions.
    • Orbitofrontal white matter lesions do not appear to compromise motor skills.
