"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
