What is attention? How does it go wrong? Do attention deficits arise from genes or from the environment? Can we cure it with drugs or training? Are there disorders of attention other than deficit disorders? The past decade has seen a burgeoning of research on the subject of attention. This research has been facilitated by advances on several fronts: New methods are now available for viewing brain activity in real time, there is expanding information on the complexities of the biochemistry of neural activity, individual genes can be isolated and their functions identified, analysis of the component processes included under the broad umbrella of "attention" has become increasingly sophisticated, and ingenious methods have been devised for measuring typical and atypical development of these processes, from infancy into childhood, and then into adulthood. In this book, Kim Cornish and John Wilding are concerned with attention and its development, both typical and atypical, particularly in disorders with a known genetic etiology or assumed genetic linkage. Tremendous advances across seemingly diverse disciplines - molecular genetics, pediatric neurology, child psychiatry, developmental cognitive neuroscience, and education - have culminated in a wealth of new methods for elucidating disorders at multiple levels, possibly paving the way for new treatment options. Cornish and Wilding use three specific-yet-interlinking levels of analysis: genetic blueprint (genotype), the developing brain, and the behavioral-cognitive outcomes (phenotype), as the basis for charting the attention profiles of six well-documented neurodevelopmental disorders: ADHD, autism, fragile X syndrome, Down syndrome, Williams syndrome, and 22q11 deletion syndrome. Their overarching aim in this book is to provide the most authoritative and extensive account to date of disorder-specific attention profiles and their development from infancy through adolescence.

This book focuses on the application of behaviour genetic approaches to twin studies, and reviews diagnostic to Attention Deficit Hyperactivity Disorder (ADHD), the relationships between reading, spelling and ADHD, and family and genetic influences on speech and speech and language.

How does the genome, interacting with the multi-faceted environment, translate into the development by which the human brain achieves its astonishing, adaptive array of cognitive and behavioral capacities? Why and how does this process sometimes lead to neurodevelopmental disorders with a major, lifelong personal and social impact? This volume of Progress in Brain Research links findings on the structural development of the human brain, the expression of genes in behavioral and cognitive phenotypes, environmental effects on brain development, and developmental processes in perception, action, attention, cognitive control, social cognition, and language, in an attempt to answer these questions. Leading authors review the state-of-the-art in their field of investigation and provide their views and perspectives for future research Chapters are extensively referenced to provide readers with a comprehensive list of resources on the topics covered All chapters include comprehensive background information and are written in a clear form that is also accessible to the non-specialist

Attention deficit hyperactivity disorder (ADHD) is a common neurobehavioral disorder affecting 5–10% of children and adolescents and 3% of adults. Attention Deficit Hyperactivity Disorder: From Genes to Patients aims to provide a comp- hensive, state-of-the-art overview of the critical aspects of ADHD, and hopefully will serve as a quick and up-to-date reference source for professionals with an int- est in ADHD. The book is divided into three major areas that follow an historical survey. The first group of chapters deals with current theories on the pathophysiology of ADHD, and focuses on neurotransmitters and the contributions and validity of animal m- els. The second section emphasizes the evaluation and treatment of patients with ADHD, from the day-to-day approach by the clinical psychologist to the more sophisticated anatomical and functional imaging strategies that have emerged in the last decade. In addition, chapters dealing with specific impairments, such as those pertaining to reading, social interaction, and working memory, are also included for more detailed analysis of these important aspects and their respective contributions to global functioning. The third and final section provides an expanded review on the pharmacotherapy of ADHD and the appropriate methods for selection of specific drugs for individual patients based on drug kinetics and gene expression.

How we raise young children is one of today's most highly personalized and sharply politicized issues, in part because each of us can claim some level of "expertise." The debate has intensified as discoveries about our development-in the womb and in the first months and years-have reached the popular media. How can we use our burgeoning knowledge to assure the well-being of all young children, for their own sake as well as for the sake of our nation? Drawing from new findings, this book presents important conclusions about nature-versus-nurture, the impact of being born into a working family, the effect of politics on programs for children, the costs and benefits of intervention, and other issues. The committee issues a series of challenges to decision makers regarding the quality of child care, issues of racial and ethnic diversity, the integration of children's cognitive and emotional development, and more. Authoritative yet accessible, From Neurons to Neighborhoods presents the evidence about "brain wiring" and how kids learn to speak, think, and regulate their behavior. It examines the effect of the climate-family, child care, community-within which the child grows.

A review of connections between genes, brain, and behavior for a range of genetic disorders, considering lifespan and treatment issues.
