Attention-deficit/hyperactivity disorder.

! Research suggests that children with difficulty in their peer relationships, like being rejected by peers or not having a close friend, may in some cases have higher risk for anxiety, behavioral and mood disorders, substance abuse and delinquency as teenagers.2 ! Parents of children with ADHD may be much less likely to report that their child plays with groups of friends or is involved in after-school activities, and half as likely to report that their child has many good friends. Parents of children with ADHD may be more than twice as likely than other parents to report that their child is picked on at school or has trouble getting along with other children.
