Book excerpt: Bringing together leading authorities, this much-needed volume synthesizes current knowledge about the nature, impact, and treatment of attention-deficit/hyperactivity disorder (ADHD) in the crucial developmental period of adolescence. Contributors explore the distinct challenges facing teens with ADHD as they navigate intensifying academic demands; new risks in the areas of driving, substance use, and romantic relationships; and co-occurring mental health problems. Best practices in clinical assessment are presented. Chapters on treatment--several of which include illustrative case examples--review interventions targeting motivation, executive functioning, and homework problems, as well as applications of cognitive-behavioral therapy and mindfulness. The book also examines medication issues specific to this age group.
