Providing a new perspective on ADHD in adults, this compelling book analyzes findings from two major studies directed by leading authority Russell A. Barkley. Groundbreaking information is presented on the significant impairments produced by the disorder across major functional domains and life activities, including educational outcomes, work, relationships, health behaviors, and mental health.

Thoughtfully considering the treatment implications of these findings, the book also demonstrates that existing diagnostic criteria do not accurately reflect the way ADHD is experienced by adults, and points the way toward developing better criteria that center on executive function deficits. Accessible tables, figures, and sidebars encapsulate the study results and offer detailed descriptions of the methods used.
