Attention deficit hyperactivity disorder (ADHD) is a complex mental health disorder that can affect your child's success at school and their relationships. The symptoms of ADHD vary and are sometimes difficult to recognize.
Many of the individual symptoms of ADHD are normal for children to experience. Evaluating the child under several criteria is necessary to make a diagnosis of ADHD. ADHD is generally diagnosed in children by the time they’re teens. The average age of diagnosis is 7. Older children exhibiting these symptoms may have ADHD, but they often have exhibited rather elaborate symptoms early in life.
