Intellectual Disability provides a comprehensive summary of knowledge acquired through my work with children, adolescents, and adults with intellectual disability for the past 30 years. It is the result of long-term contact with intellectually disabled persons and their families and discussions with faculty members, residents, and medical students and nonmedical professionals at the Johns Hopkins Medical Institutions and the Kennedy-Krieger Institute. Gratitude is expressed to the many authors whose publications that I have referenced and that have enhanced my understanding. I assume full responsibility for my synthesis of their work. I thank Eunice Kennedy Shriver, director of the Joseph P. Kennedy, Jr. Foundation, for her inspiration and example of dedication to intellectually disabled persons all over the world. My teachers and colleagues, Robert E. Cooke, medical director of the Joseph P. Kennedy, Jr. Foundation, and Hugo Moser, past president of the Kennedy-Krieger Institute, have instilled their scientific passion for understanding the etiologies of intellectual disability. Appreciation is expressed to Bryan King and Ludwik Syzmanski, who reviewed the draft manuscript and provided valuable recommendations for its improvement, and to my wife, Catherine DeAngelis, for her infinite patience.
I particularly thank Irving B. Harris of the Irving B. Harris Foundation for financial support that allowed me to complete this book. Special thanks are due to Joan Bossert, my editor at Oxford University Press, who provided continuing support and insightful suggestions regarding the publication of this book. Finally, without the unfailing efforts and diligence of Joan Bendall, this book could not have been completed.
