Although the phenomenon of ADHD (Attention-Deficit Hyperactivity Disorder) is well described in children, it is now thought that in up to 60% of cases the symptoms persist into adulthood. This volume reviews our growing knowledge of adult ADHD and presents a transatlantic perspective on the identification, assessment and treatment of the disorder. The introductory section covers the history of ADHD, as well as the epidemiology, consequences, gender differences and legal aspects. Detailed descriptions of the clinical features of ADHD in adults are then given to enhance the reader’s clinical recognition and assessment. Subsequent sections cover treatment strategies, emphasising pharmacological, psychological and social interventions. Written and edited by experts internationally renowned for their work in ADHD, this is an essential resource for all mental health workers who encounter adults presenting with neurodevelopmental disorders.
