Children with ADHD are at a high risk for other problems. Some experience trouble with learning, such as reading and language processing difficulties that are not just the result of inattention. Some children with ADHD have difficulty in regulating their behavior to follow rules and can be quite obstinate and resistant to limits and authority. Because children and adolescents with ADHD tend to seek excitement, feel bored more easily and spend little time planning things through, some gravitate toward thrill-seeking behaviors.
Anxiety and depression are more common in children with ADHD than in the general population. Some children may be so worried that they find it hard to stay focused on academic work. Similarly, sad children are also less likely to stay focused and to feel motivated to keep up with school demands. If they are irritable, they may resist direction or lash out.
