Objective: to determine the factors influencing quality of life (QoL) in patients with drug-resistant focal epilepsy (DRFE). Material and methods. 111 adult patients with DRFE were included in the study. Quality of life was measured using the Quality Of Life In Patients with Epilepsy – 31 questionnaire (QOLIE-31). The severity of the disease (frequency and subjective assessment of the severity of seizures), the effect of pharmacotherapy (drug load and composition of the treatment regimen), the social status of patients, comorbid conditions (anxiety and depressive disorders, pathological fatigue) were assessed. Results. In the studied sample, a pronounced decrease in QoL was shown, the median of the final QOLIE-31 score was 65.4 points (interquartile range 53.0–72.6 points). A statistically significant decrease in QoL was found in subgroups of patients with seizures during the previous three months; taking carbamazepine or benzobarbital; with anxiety and depressive disorders; with pathological fatigue; and in unemployed patients. A multiple linear regression model (R2=0.66) was developed, which included the following determinants: Fatigue Severity Scale, Liverpool Seizure Severity Scale, and the risk of depression according to the NDDI-E questionnaire. Conclusion. In patients with drug-resistant focal epilepsy, there is a pronounced decrease in the quality of life due to combination of factors associated with the characteristics of the disease, treatment, comorbidities, and social status. The key QoL determinants in patients with DRFE are pathological fatigue, anxiety and depression, and subjective severity of epileptic seizures; employment is a positive factor. The role of epileptic seizures frequency in QoL formation in these patients requires further research.
