A systematic review of epilepsy cost-of-illness studies was conducted, with adjustments made to generate single per-person and epilepsy-attributable total healthcare and indirect costs, and estimated costs for countries with missing data according to those of countries in the same income category.1 Data from the Global Burden of Disease study was used to estimate the prevalence of epilepsy.1 Costs were calculated for US dollar values in 2019.1 A total of 101 studies was included for the estimation of healthcare costs, and 13 studies were included for estimation of indirect costs.1 The treatment gaps (people not diagnosed or receiving treatment for epilepsy) data was obtained from the published literature.1 For all the cost data there were substantial gaps between each level of country income, with total healthcare costs of $0.2 billion in LICs, $4.3 billion in LMICs, $28.5 billion in UMICs, and $45.9 billion in HICs.1
