Abstract

BACKGROUND: Epilepsy has been known to adversely affect a patient's quality of life (QOL). We investigated the status of QOL and tested the influences of clinical factors upon QOL in epileptic patients.
METHODS
We evaluated 125 adult patients (mean age, 30.4 years, male:female=1:0.86) with epilepsy. The demographic, social (marriage, employment, religion, education duration), and clinical data (seizure onset age, seizure pattern during the last 1 year, treatment duration, number of antiepileptic drug) were obtained. Quality of life in epilepsy-31 (QOLIE-31) and Beck Depression Inventory-Korean version (KBDI) were used. The relationships of demographic, social, and clinical factors with QOL in epileptic patients were evaluated.
RESULTS
The mean subscores of QOLIE-31 items were 52.6 (medication effects), 50.9 (cognitive functioning), 50.9 (social functioning), 50.5 (energy/fatigue), 48.4 (seizure worry), 46.8 (overall QOL), and 45.7 (emotional well-being), and the overall score was 49.6. Sex, marriage, religion, and duration of treatment did not affect QOL. The age of patients had a weak linear positive correlation with overall QOL and emotional well-being. Employed patients had a significantly high score in overall QOL, emotional well-being, cognitive functioning, social functioning, and overall score. The patients given polytherapy had lower scores of QOLIE-31 items except seizure worry and energy/fatigue. Seizure free patients had significantly higher scores in seizure worry, overall QOL, social functioning, and overall score. Depression negatively influenced all subscales and overall score.
CONCLUSIONS
Age, employment state, number of antiepileptic drugs, seizure pattern, and depression were significant clinical factors affecting QOL in patients with epilepsy.
