Objective: Epilepsy is one of the most common neurological disease. Epilepsy and sleep have a bidirectional relationship. Epilepsy can cause sleep disorder in patients. Concurrently, poor sleep quality or sleep disorder may trigger epileptic seizure. Understanding this relationship can provide early intervention for better sleep and epilepsy control including screening and preventing possible following comorbidities.

Methods: A cross-sectional study was conducted at Ramathibodi Hospital, Bangkok, Thailand. A Total of 122 patients, diagnosed by a neurologist as those who had epilepsy, were recruited at the outpatient neurology clinic of the hospital. In this study, the demographic data of all patients was collected. All participants were evaluated for their sleep quality, using a Thai version of the Pittsburgh sleep quality index questionnaire. The prevalence of poor sleep quality was determined. The correlation between potential variables and the presence of sleep quality in patients with epilepsy was analyzed using t-test, chi-square and Fisher’s exact test.

Results: From our findings, the prevalence of poor sleep quality was 53.27%. Poor sleep quality was found to be statistical significance correlated with temporal lobe epilepsy (p<0.01) and age (p=0.01).

Conclusion: The prevalence of poor sleep quality among Thai patients with epilepsy was high especially in temporal lobe epilepsy and older patients. Awareness and Screening for sleep quality in patients with epilepsy could help physician provide early intervention for better sleep, control epilepsy and improve patients’ quality of life.
