The primary characteristic of ADD without hyperactivity is significant inattentiveness. Studies of children with this diagnosis indicate that they show more signs of anxiety and learning problems, and qualitatively different inattention. Although there have been no adult follow-up studies, it is projected that children who have ADD without hyperactivity may have different outcomes than the hyperactive group, who show more externalizing behavior problems associated with oppositional and conduct disorders.
