Download or read book Essential Pathways and Circuits of Autism Pathogenesis written by Gül Dölen and published by Frontiers Media SA. This book was released on 2016-08-15 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Centers for Disease Control and Prevention estimate that 1 in 68 children in the United states is afflicted with autism spectrum disorders (ASD), yet at this time, there is no cure for the disease. Autism is characterized by delays in the development of many basic skills, most notably the ability to socialize and adapt to novelty. The condition is typically identified in children around 3 years of age, however the high heritability of autism suggests that the disease process begins at conception. The identification of over 500 ASD risk genes, has enabled the molecular genetic dissection of the pathogenesis of the disease in model organisms such as mice. Despite the genetic heterogeneity of ASD etiology, converging evidence suggests that these disparate genetic lesions may result in the disruption of a limited number of key biochemical pathways or circuits. Classification of patients into groups by pathogenic rather than etiological categories, will likely aid future therapeutic development and clinical trials. In this set of papers, we explore the existing evidence supporting this view. Specifically, we focus on biochemical cascades such as mTOR and ERK signaling, the mRNA network bound by FMRP and UBE3A, dorsal and ventral striatal circuits, cerebellar circuits, hypothalamic projections, as well as prefrontal and anterior cingulate cortical circuits. Special attention will be given to studies that demonstrate the necessity and/or sufficiency of genetic disruptions (e.g. by molecular deletion and/or replacement) in these pathways and circuits for producing characteristic behavioral features of autism. Necessarily these papers will be heavily weighted towards basic mechanisms elucidated in animal models, but may also include investigations in patients.
Download or read book Development of the Cerebellum from Molecular Aspects to Diseases written by Hassan Marzban and published by Springer. This book was released on 2017-07-27 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors present the most current and cutting-edge knowledge regarding the molecular basis of cerebellar development, focusing on information relevant to laboratory scientists and clinicians providing service to patients with cerebellar disorders. Knowledge obtained from advanced neuroimaging techniques that are used during development, and from molecular- and genetic-based studies has provided rapidly-growing evidence that the cerebellum is a brain region that is highly impacted by developmental defects. Cerebellar defects result in significant intellectual and motor function impairment that affects both the patients and their families.

Researchers and graduate students alike with an interest in developmental disorders and autism will benefit, as will autism specialists across psychology and medicine looking to expand their expertise. Uniquely explores ASDs from a neurobiological angle, looking to uncover the molecular/cellular basis rather than to merely catalog the commonly used behavioral interventions Comprehensive coverage synthesizes widely dispersed research, serving as one-stop shopping for neurodevelopmental disorder researchers and autism specialists Edited work with chapters authored by leaders in the field around the globe - the broadest, most expert coverage available
Download or read book Autism Spectrum Disorders written by Andreas M. Grabrucker and published by . This book was released on 2021 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Autism and the Environment written by Institute of Medicine and published by National Academies Press. This book was released on 2008-03-12 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Autism spectrum disorders (ASD) constitute a major public health problem, affecting one in every 150 children and their families. Unfortunately, there is little understanding of the causes of ASD, and, despite their broad societal impact, many people believe that the overall research program for autism is incomplete, particularly as it relates to the role of environmental factors. The Institute of Medicine's Forum on Neuroscience and Nervous System Disorders, in response to a request from the U.S. Secretary of Health and Human Services, hosted a workshop called "Autism and the Environment: Challenges and Opportunities for Research." The focus was on improving the understanding of the ways in which environmental factors such as chemicals, infectious agents, or physiological or psychological stress can affect the development of the brain. Autism and the Environment documents the concerted effort which brought together the key public and private stakeholders to discuss potential ways to improve the understanding of the ways that environmental factors may affect ASD. The presentations and discussions from the workshop that are described in this book identify a number of promising directions for research on the possible role of different environmental agents in the etiology of autism.

Download or read book Neural and Synaptic Defects in Autism Spectrum Disorders written by Hansen Wang and published by Frontiers Media SA. This book was released on 2015-07-07 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Autism spectrum disorders (ASDs) are a group of genetically and clinically heterogeneous neurodevelopmental disorders characterized by impaired reciprocal social interactions and communication, and restricted and repetitive patterns of behaviors and interests. Studies in genetics, neurobiology and systems biology are providing insights into the pathogenesis of ASDs. Investigation of neural and synaptic defects in ASDs not only sheds light on the molecular and cellular mechanisms that govern the function of the central nervous system, but may lead to the discovery of potential therapeutic targets for autism and other cognitive disorders. Our Research Topic which constitutes this e-book documents the recent development and ideas in the study of pathogenesis and treatment of ASDs, with an emphasis on syndromic disorders such as fragile X and Rett syndromes. In addition, model systems and methodological approaches with translational relevance to autism are covered herein. We hope that the Research Topic will enhance the global knowledge base in the autism research community and foster new research directions in autism related biology.

Download or read book The Neurology of Autism written by Mary Coleman and published by Oxford University Press. This book was released on 2009-04-23 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Neurology of Autism, Mary Coleman, Catalina Betancur, G. Robert DeLong, Christopher Gillberg, Yoshiko Nomura, Lorenzo Pavone, Martin Ruggieri, and Michele Zappella use the tools of neurological analysis to address a number of the major questions that have arisen in the study of autism. The answers they present have important implications for the direction of future autism research, diagnosis, and treatment. What are the neurological signs and symptoms of autism? The latest information is presented here in an in-depth discussion of epilepsy, cranial circumference, changes in muscle tone, stereotypies, and mutism found in children with autism. In addition, a template is provided for practitioners to follow when conducting neurological examinations of a child with autism. What are the best options for the treatment of autism? The current medical, educational, and alternative therapies are thoroughly reviewed and evaluated. Is autism reversible? The question is explored for syndromic autism, where diseases may have a transient autistic phase, and reviewed in detail for nonsyndromic autism. Is autism primarily a single disease, as originally described by Leo Kanner? Research presented here suggests that autism is, instead, a syndrome involving many disease entities. Has the incidence of autism been increasing in recent years? A sophisticated, historical review of autisms prevalence rates suggests that it has never been rare. What is the relationship between autism and Asperger syndrome? The latest evidence presented here sheds light on the degree to which both syndromes share more than clinical characteristics; they also have some similar findings in imaging, neuropathological, and genetic studies. Which components of the brains neural networks need to be impaired to cause the appearance of autistic symptoms? Although there are many candidate regions, dysfunction of the cerebellum and its circuits is noted to be of great interest. Student and professional researchers, practitioners, and parents will find this book to be a valuable resource for both the latest information from basic-science research and its application to the diagnosis and treatment of autism. "[This book] includes up-to-date genetic evidence, underlining the complexities of genetic/environmental influences...I recommend this easy and informative read." -European Journal of Pediatric Neurology "...authoritative." -The Lancet Neurology "Coleman's new book is an absolute must-read for anyone interested in the progress made in understanding the causes of autism. The field owes her a tribute worthy of someone who has transformed an area of neuroscience." -Simon Baron-Cohen in Nature Neuroscience "[I]nformative and comprehensive in its treatment of the neurologic basis of autism...well written and easy to understand...the contributing authors have done an excellent job of making complex medical concepts understandable to all. The glossary at the end of the book is extremely helpful in this regard. The book is well referenced, provides helpful tables throughout, and includes a summary of relevant points at the end of each chapter.The authors are to be commended for presenting a very balanced view of current knowledge; they also indicate what we do not yet understand about brain functioning in autism and provide an important road map for ongoing exploration." -Marshalyn Yeargin-Allsopp in The New England Journal of Medicine "At last it is recognised that developmental neurology is the appropriate context in which to explain autism. The authors of this volume, all pioneers in the field, consider new ideas on autism in this context. They succeed in making surprising and illuminating comparisons between autism and neurological disorders whose origin is already known. This work is a significant step towards understanding the causes of autistic disorders."-Uta Frith, Institute of Cognitive Neuroscience and Department of Psychology, University College London "When and if the secret of autism is teased from the myriad disease states that exhibit the syndrome, it will be through efforts such as are represented in this volume. Dr. Coleman has 'picked the brains' of recognized experts from neurology and related sciences, and has assembled a wealth of up-to-date and meticulously referenced information regarding both those diseases and the core symptoms of autism." -Peter B. Rosenberger, Massachusetts General Hospital
Download or read book Comprehensive Guide to Autism written by Vinood B. Patel and published by Springer. This book was released on 2013-10-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Autism is a complex multifaceted disorder affecting neurodevelopment during the early years of life and, for many, throughout the life span. Inherent features include difficulties or deficits in communication, social interaction, cognition, and interpersonal behavioral coordination, to name just a few. Autism profoundly impacts the affected individual, the family, and, in many cases, the localized communities. The increased prevalence of childhood autism has resulted in rapid developments in a wide range of disciplines in recent years. Nevertheless, despite intensive research, the cause(s) remain unresolved and no single treatment strategy is employed. To address these issues, Comprehensive Guide to Autism is an all-embracing reference that offers analyses and discussions of contemporary issues in the field of autism. The work brings together scientific material from leading experts in the field relating to a wide range of important current topics, such as the early identification and treatment of children with autism, pertinent social and behavioral studies, recent developments in genetics and immunology, the influence of diet, models of autism, and future treatment prospects. Comprehensive Guide to Autism contains essential readings for behavioral science researchers, psychologists, physicians, social workers, parents, and caregivers.

Download or read book Autism written by Roberto Tuchman and published by Mac Keith Press. This book was released on 2006-06-09 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by child neurologists, this comprehensive, multi-authored volume on autism systematically discusses the classification, epidemiology and neurobiology of autism. Autism lacks a unique etiology or specific pathology, so the behaviorally defined social deficits, language impairments and repetitive behaviors that define autism are explored from a developmental neurology perspective. The evidence suggesting that autism is a disorder of neuronal development is reviewed by experts on the genetics, neuroanatomy and neuroradiology, neurochemistry, immunology, and neurophysiology of autism. Chapters provide comprehensive reviews of the common neurological problems associated with autism such as epilepsy, sleep disturbances and motor and sensory deficits. Neuropsychological assessment, medical and psychopharmacologic management, educational and behavioral interventions, and outcome are discussed within the clinical content of the practising neurologist. The research agenda needed to understand the neurology of autism is emphasized throughout the book and in the conclusion.
