Three approaches have been taken so far in reducing the heterogeneity of ADHD cases. The first, based on subtyping as in the DSM-IV, has largely failed to reveal clinically or scientifically meaningful differences. The second, based on etiology, is promising but of little clinical value at the moment. The third approach having by far the greatest clinical and scientific utility has been using comorbidity. As this book attests, using comorbidity to better understand ADHD has been an approach yielding reams of valuable information about the life course and forms of impairments likely to be associated with ADHD, the types of treatments that need to be used or adjustments to them for various comorbidities, and even the likely response to traditional ADHD treatments. This is the most up-to-date book on this topic currently available and richly rewards the reader, whether clinician, scientist, or student, with its substantial breadth of coverage and detail.—Russell A. Barkley, Ph.D., Clinical Professor, Medical University of South Carolina (Charleston) and Research Professor, SUNY Upstate Medical University (Syracuse)

This book offers a rich compendium of information about what is currently known about ADHD and how it can be most effectively treated in all its complexities.—From the Foreword, F. Xavier Castellanos, M.D., New York University Child Study Center and Nathan Kline Institute for Psychiatric Research

Every conceivable psychiatric comorbidity is covered, by experts in each. Specific chapters are devoted to assessment of ADHD and comorbid disorders and the variety of treatments—pharmacotherapy, psychosocial interventions, cognitive therapy for adults, and tailoring treatment to best fit each person and family. Given the high prevalence of ADHD, this volume should be on every clinician's shelf.—Mina K. Dulcan, M.D., Osterman Prof Child Psychiatry, Children's Mem Hosp; Head, Child Psychiatry, Children's Mem Hosp & Northwestern Mem Hosp; Head, Child Psychiatry, Northwestern Univ School of Med

In accessible language, more than 30 researcher-clinician contributors summarize how to recognize ADHD and its comorbidities at various stages of development, from preschool age to adolescence to adulthood. Clinician will find practical help-and acquire valuable guidance on tailoring medications and other interventions to optimize treatment outcomes for patients of all ages with complex cases of ADHD.—ATTENTION Magazine, 2/1/2009

It is a comprehensive and exhaustive volume, with ample references, suggestions for further readings, and even useful web sites. While the information can be overwhelming, the variety of therapeutic responses to the syndrome—from cognitive and behavioral therapy to appropriate medication—offer a glimmer of hope for concerned teachers and beleaguered family members.—Education updated.com, 2/1/2009

This handbook makes an important contribution to the field by highlighting the developmental and genetically mediated nature of ADHD, its potential influences on other psychopathology into adulthood, empirical findings regarding the nature of virtually all ADHD comorbidities, and the implications for and best practices in assessment.—Will H. Canu, Journal of Attention Disorders, 2/1/2009
