Quantitative analysis of interictal behavior in temporal lobe epilepsy

D M Bear, P Fedio

    Archives of Neurology
    |August 1, 1977
    PubMed
    Summary

    Temporal lobe epilepsy patients exhibit unique psychosocial behaviors, differing from controls. Hemispheric differences in temporal lobe epilepsy impact emotional and ideational expression, supporting theories of affect processing.

    Area of Science:

    • Neuroscience
    • Psychology
    • Behavioral Science

    Background:

    • Temporal lobe epilepsy (TLE) is associated with behavioral changes.
    • Understanding the psychosocial aspects of TLE is crucial for patient care.
    • Previous research suggests lateralization of function within the temporal lobes.

    Purpose of the Study:

    • To investigate specific psychosocial behavioral differences in patients with unilateral temporal epileptic foci.
    • To compare these patients with normal subjects and those with neuromuscular disorders.
    • To explore hemispheric asymmetries in the expression of affect and ideation.

    Main Methods:

    • Utilized equivalent questionnaires assessing 18 behavioral traits.
    • Collected data from both patients and independent observers.
    • Contrasted patients with unilateral temporal epileptic foci against control groups.

    Main Results:

    • Epileptic patients reported distinct traits: humorless sobriety, dependence, and obsessionalism.
    • Observers identified TLE patients by circumstantiality, philosophical interests, and anger.
    • Right temporal epileptics showed emotional tendencies; left temporal epileptics displayed ideational traits.
    • Right TLE patients exhibited denial; left TLE patients showed overemphasis on dissocial behavior.

    Conclusions:

    • Sensory-affective associations are indeed established within the temporal lobes.
    • Evidence supports hemispheric asymmetry in affect expression in humans.
    • These findings contribute to understanding the neurobiological basis of behavior in TLE.
