Objective: We investigated the economic burden and disability-adjusted life years (DALYs) for attention deficit/hyperactivity disorder (ADHD) in the Republic of Korea. Method: Using the National Health Insurance Service claims data for the population aged 19 years or younger, a prevalence-based approach was used to calculate the DALYs of ADHD. Direct medical costs, direct nonmedical costs, and indirect costs resulting from ADHD were estimated to calculate the economic burden of ADHD. Results: A total of 69,353 people in Korea were diagnosed with ADHD in 2012. The burden of ADHD as measured by the prevalence-based approach was 32,605 DALYs. The total economic burden of ADHD was US$47.55 million, which accounted for approximately 0.004% of Korean GDP (gross domestic product) in 2012. Conclusion: Our findings shed light on the considerable burden of ADHD, emphasizing the need for policies that can encourage ADHD treatment and enhance compliance.
