Global, regional, and national burdens of attention deficit hyperactivity disorder in adolescents and young adults aged 10–24 years from 1990 to 2021: A trend analysis

Over the past 30 years, there has been a general downward trend in the incidence and prevalence of ADHD and in the rate of DALYs worldwide. However, phased studies have shown less homogeneous trends in recent years, which may be related to changes in the level of socioeconomic development, diagnostic criteria, and therapeutic approaches. Therefore, it is necessary to continue to promote research on the accuracy and universality of ADHD diagnosis and treatment in the future, with a view to further reducing the global health burden of ADHD.
