Book Description
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.

Attention, Genes, and ADHD
Author: Florence Levy
Publisher: Psychology Press
ISBN: 9781841691930
Category : Family & Relationships
Languages : en
Pages : 296
Book Description
Recent advances in genetic methodology are providing important aetiological and developmental information to the growing literature on Attention Deficit Hyperactivity Disorder (ADHD) and related conditions. Attention, Genes and ADHD is the first book to review and integrate both behaviour-genetic and molecular-genetic advances in this area. It brings together international researchers to show how modern techniques may be applied to the investigation of ADHD, and reviews current findings in the field of ADHD and related conditions. The book looks at the application of behaviour genetic approaches to twin studies, and reviews diagnostic to ADHD, the relationships between reading, spelling and ADHD, and family and genetic influences on speech and speech and language. Chapters go on to consider the overlaps between ADHD, Oppositional Defiant Disorder and Conduct Disorder and to explore the environmental and genetic influences among these disorders. The neurobiological and genetic relationship between ADHD and Tourette's Disorder is also examined. The book reviews recent advances in molecular genetics - in particular a discussion of Fragile X as a model for a single single gene effects on ADHD, and the application of genetic methods and approaches to the study of candidate genes. Finally, the implications for education and intervention are discussed, and current and future roles of gentic studies of ADHD are explored, as well as implications of the sequencing of the human genome for child psychiatry.

ADHD in Adults
Author: Russell A. Barkley
Publisher: Guilford Press
ISBN: 1609180755
Category : Psychology
Languages : en
Pages : 513
Book Description
Providing a new perspective on ADHD in adults, this compelling book analyzes findings from two major studies directed by leading authority Russell A. Barkley. Groundbreaking information is presented on the significant impairments produced by the disorder across major functional domains and life activities, including educational outcomes, work, relationships, health behaviors, and mental health. Thoughtfully considering the treatment implications of these findings, the book also demonstrates that existing diagnostic criteria do not accurately reflect the way ADHD is experienced by adults, and points the way toward developing better criteria that center on executive function deficits. Accessible tables, figures, and sidebars encapsulate the study results and methods.

From Neurons to Neighborhoods
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309069882
Category : Social Science
Languages : en
Pages : 610
Book Description
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.

Autism Spectrum Disorders
Author: Andreas M. Grabrucker
Publisher:
ISBN:
Category :
Languages : en
Pages : 117
Book Description
Autism spectrum disorders are developmental disorders. Individuals with autism spectrum disorders develop differently. These differences are usually present in social interaction, communication, and sensory processing, and become visible through a wide variety of behavioral responses that differ from individuals without autism spectrum disorders. Despite significant research efforts, the exact causes of autism spectrum disorders remain poorly understood; however, researchers have gained extensive insights into possible pathomechanisms, even at the molecular level of cells. Many diagnostic criteria have been developed, adapted, and improved. The eight chapters in this book highlight the current state-of-the-art in many areas of autism spectrum disorders. Chapter 1 provides an overview of the epidemiology of autism spectrum disorders and the current knowledge of the underlying pathogenic mechanisms. Chapter 2 summarizes the diagnostic criteria and procedures and highlights present and upcoming therapeutic strategies. Chapter 3 reviews the adverse events and trauma in people with autism spectrum disorders. Chapters 4 and 5 focus on atypical sensory processing, and Chapter 6 discusses the genetic overlap of autism spectrum disorders with other neuropsychiatric disorders such as attention deficit hyperactivity disorder (ADHD), depression, and schizophrenia. Chapter 7 focuses on the contribution of abnormalities in mitochondria, and chapter 8 discusses gut-brain interactions and a potential role for microbiota in autism spectrum disorders. This book is aimed primarily at clinicians and scientists, but many areas will also be of interest to the layperson.

Neuropsychiatric Disorders and Epigenetics
Author: Jacob Peedicayil
Publisher: Elsevier
ISBN: 0443185174
Category : Science
Languages : en
Pages : 418
Book Description
Neuropsychiatric Disorders and Epigenetics, Second Edition is a comprehensive reference on the epigenetic basis of common neuropsychiatric disorders. The volume is organized into chapters covering individual neuropsychiatric disorders, from addiction to anxiety and autism spectrum disorders, and is contributed by leading experts in their respective fields. The epigenetic aspects of each disorder are discussed, in the context of the full range of associated epigenetic mechanisms, including DNA modification, histone post-translational modification, chromatin organization, and non-coding RNA. A particular emphasis is placed on potential epigenetic interventions, when the effects of environmental stimuli on epigenetic states is particularly relevant to disease.This new edition has been fully updated to reflect recent research advances enabled by genomic technologies, as well as therapeutic interventions for previously unmanageable disorders. Several new chapters have been added on disorders or approaches not considered in the earlier edition, including epigenetics and anxiety disorders, epigenetics and neuroimaging in neuropsychiatric disorders, genome-wide approaches to epigenetic research, and the epigenetics of spinal muscular atrophy. By helping to define epigenetics as a key player in neuropsychiatric disorders, this volume empowers new research, clinical translation, and pharmacological advances, and highlights promising directions for ongoing investigation. - Analyzes the effects of environmental stimuli on epigenetic states that correlate with neuropsychiatric disease induction - Reviews the epigenetic basis for common neuropsychiatric disorders, thereby guiding translational therapies for clinicians and mechanistic studies for scientists - Features extensive use of diagrams, illustrations, tables, and graphical abstracts for each section to reinforce understanding - - Includes chapter contributions from leading global experts

Category : Psychology
Languages : en
Pages : 912
Book Description
A unique, multi-discipline, developmental approach to childhood psychopathology Child and Adolescent Psychopathology is the only comprehensive text in the field to address genetic, neurobiological, and environmental factors within a developmental context. Based on cutting-edge research and aligned with the DSM-5, this book emphasizes how, when, and why disorders emerge among young people, and the ways in which symptom profiles change at different stages of development. This new third edition has been updated to include new chapters on OCD and trauma disorders consistent with DSM-5 classification, and includes new discussion on epigenetics and the neighborhood effects on the development of delinquency. Coverage includes extensive discussion of risk factors, from disturbed attachment relations and abuse/neglect, to head injury and teratogen exposure, followed by in-depth examination of behavior disorders and psychological disorders including Autism Spectrum, Schizophrenia Spectrum, and Eating Disorders. Psychological disorders in children are increasingly being explored from a relational perspective, and continuous advances in neurobiology research are adding an additional dimension to our understanding of cause, effect, and appropriate intervention. This book provides detailed guidance toward all aspects of childhood psychopathology, with a multi-discipline approach and a unique developmental emphasis. Discover how psychopathology emerges throughout the stages of development Learn how both genetics and environmental factors influence risk and behaviors Understand the prevalence, risk factors, and progression of each disorder Gain deep insight from leading experts in neurobiology and developmental psychopathology As the field of child psychology continues to evolve, behavioral and psychological disorders move beyond a list of symptoms to encompass the 'whole child'—biology, chemistry, environment, and culture are becoming increasingly relevant in understanding and treating these disorders, and must be considered from the earliest assessment stages. Child and Adolescent Psychopathology provides comprehensive information on childhood disorders from a developmental perspective.
