Recent longitudinal studies of childhood attention-deficit/hyperactivity disorder: Important themes and questions for further research.

What we can see from the studies included here are that most cases of attention-deficit/hyperactivity disorder (ADHD) persist from the preschool years into elementary school and on into adolescence, although trajectories vary considerably across individuals. Several studies here identified a small set of unique developmental trajectories for the symptoms of ADHD. All in all, the longitudinal studies of ADHD included here have greatly advanced our understanding of the developmental course and outcomes associated with childhood ADHD.
