[Transition psychiatry: attention deficit/hyperactivity disorder]

Transition psychiatry: attention deficit/hyperactivity disorder Abstract. Attention deficit/hyperactivity disorder affects 5 % of all children and adolescents and 2-3 % of all adults. It is thus one of the most frequent neurodevelopmental disorders, frequently associated with comorbid disorders and multiple functional impairments. Administrative data indicate that many patients with ADHD are at a great risk for treatment discontinuation during the transition to adulthood despite persistent symptomatology and functional impairment. The article addresses potential consequences for optimizing ADHD treatment during this transition.
