"This energetic and informative book tackles head-on the knotty issue of what ADHD in adults really means. It includes helpful answers to such vital problems as what modifications to diagnostic criteria are appropriate, and what are the inferential biases to which clinicians are prone when seeing self-referred cases in their offices. This is the most definitive work to date on the difficult task of generalizing from children with ADHD to adults with ADHD. The authors break new ground in addressing these issues with comprehensive data from their own well-regarded samples. This timely book thus provides a fresh and needed perspective to help resolve longstanding difficulties in understanding ADHD in adults. It will be helpful to DSM-V committee deliberations and to those planning future scientific studies, as well as to clinicians needing a clearer picture of what to expect in adults with ADHD."--Joel T. Nigg, PhD, Department of Psychology, Michigan State University

"A veritable tour de force. This work will be equally useful to researchers seeking innovative hypotheses about ADHD, to clinicians seeking to understand the course of ADHD into adulthood, and to students at all levels of training. Readers have access to a unified and systematic view of the results from two notable, methodologically rigorous research studies. The book addresses a wide range of clinically urgent issues, such as psychiatric comorbidity, drug use, life impairments, educational attainment, and neuropsychological impairment. The discussions of diagnostic criteria not only provide clinically useful information for adult assessment, but also should strongly influence the evolution of the DSM-V."--Stephen V. Faraone, PhD, Department of Psychiatry and Behavioral Sciences; Director, Medical Genetics Research; and Director, Child and Adolescent Psychiatry Research, SUNY Upstate Medical University

"The single best source of scientific information on adult ADHD available to date. The results of two major research investigations are thoroughly reviewed to explicate important similarities and differences between children with ADHD followed into adulthood and individuals first referred for ADHD symptoms as adults. This is the first text to make this important and clinically relevant distinction. It is sure to be an indispensable resource for both clinicians and researchers. In addition, graduate students in clinical psychology, counseling, social work, and school psychology will find this text helpful both for the data it provides about adult ADHD and for its insights into how to establish a coherent research agenda."--George J. DuPaul, PhD, Department of Education and Human Services, Lehigh University
