The new edition of this popular text incorporates the latest research on assessment and treatment practices for adults with attention-deficit/hyperactivity disorder (ADHD). The presentation of symptoms may differ considerably in adulthood and without appropriate symptom management, ADHD can significantly interfere in many aspects of life. When properly identified and diagnosed, however, outcomes in adults with ADHD who receive appropriate treatment are encouraging. This volume is both a compact “how to” reference for use by professionals in their daily work and an ideal educational reference for students, informing the reader of all aspects involved in the assessment and management of ADHD in adults. This edition also explores how psychosocial adversity factors impact the development and functional impairments associated with ADHD and highlights strategies used in the multimodal treatment of ADHD in adults. Best practice approaches are offered for common problems encountered when carrying out treatments. A companion volume Attention-Deficit/Hyperactivity Disorder (ADHD) in Children and Adolescents is also available.
