Methods and materials: An institution-based cross-sectional study design was implemented among patients with epilepsy attending the neurology clinic of TASH and ZMH. Data was collected from patients and medical records using a structured questionnaire and data abstraction format respectively. Descriptive analysis was conducted to summarize the socio-demographic and clinical characteristics of participants.
