Epilepsy patients exhibit distinct personality traits, including ideational and obsessive-compulsive features, compared to healthy individuals. Chronic conditions like psoriasis may also influence personality, suggesting broader impacts beyond cerebral dysfunction.

Area of Science:

  • Neuropsychology
  • Psychiatry
  • Dermatology

Background:

  • Epilepsy, particularly temporal lobe epilepsy (TLE) and primary generalized epilepsy (PGE), is associated with behavioral changes.
  • Personality characteristics in epilepsy patients have been studied using modified inventories, such as the Bear-Fedio inventory.

Purpose of the Study:

  • To investigate personality characteristics in patients with TLE and PGE.
  • To compare personality traits between epilepsy patients, psoriasis patients, and healthy volunteers.
  • To identify specific personality dimensions associated with epilepsy and chronic illness.

Main Methods:

  • A questionnaire study using a modified Bear-Fedio inventory.
  • Inclusion of patients with TLE, PGE, psoriasis patients, and healthy controls.

  • Analysis using Rasch models and logistic regression.

    • Main Results:

    • Four personality dimensions were identified: ixoide, ideational, obsessive-compulsive, and affective features.
    • Rasch model analysis supported all dimensions except affective features.
    • Epilepsy patients scored highest, healthy volunteers lowest, and psoriasis patients showed intermediate scores across dimensions.
    • Ixoide features were most significant when comparing epilepsy patients to controls; ideational features distinguished TLE from PGE.

    Conclusions:

    • Epilepsy is associated with specific personality trait dimensions, notably ixoide and ideational features.
    • The intermediate personality profile of psoriasis patients suggests that chronic disorders with social stigma can influence personality, independent of cerebral dysfunction.
    • Personality assessment in chronic conditions requires consideration of both neurological and psychosocial factors.
