In Reply We thank Solanto for her interest in our article1 and for providing some thoughtful ideas on how to understand these intriguing similar findings from 3 population samples that challenge the notion of attention-deficit/hyperactivity disorder (ADHD) as only a child-onset neurodevelopmental disorder.2,3 Solanto suggests that our study1 might have missed a substantial proportion of cases of ADHD predominantly inattentive type (ADHD-PI) in childhood, consequently decreasing the rate of adult ADHD with roots in childhood. She based this hypothesis on the idea that we had collected data on ADHD symptoms in childhood before DSM-IV criteria.
