Attention Deficit Hyperactivity Disorder (ADHD) is estimated to affect between 3 and 7% of school-aged children. It can affect children's home, school and community life leading to poor peer relations, aggression and learning problems, which, in turn, can lead to academic failure and an increased risk of depression. However, there has been conflicting evidence about the relationship between ADHD symptoms and low self-esteem. A Swedish study of 1,714 children, which followed them between the ages of 8 and 13 measured their ADHD symptoms and self-esteem when they were eight and again when they were thirteen. The children with high levels of ADHD symptoms had lower scores in the aspects of self-esteem relating to "skills and talents" and "psychological well-being."
