In this advanced level essay Attention-Deficit/Hyperactivity Disorder (ADHD) is discussed within a Swedish Sports setting and the purpose is to better understand why children and adolescents with ADHD in Sweden drop out of sports clubs at an earlier than average age. This study is based on an interpretive view of knowledge and has a qualitative method. Through interviews with various experts of ADHD and other neurodevelopmental disorders the study aims at understanding the reasoning of children with ADHD as they navigate the complex cultural and institutional environments found in sports. Erving Goffman's theories about stigma are utilized in the study to further understand the relationships between youth with ADHD and coaches, other parents and peers in sports. ADHD is often stigmatized in social interactions in sport and the power that coaches, and other “normal” people have over the youth with ADHD can be considered a key to understanding why ADHD is stigmatized and why so many drop out at an early age.
