Available in PDF, EPUB and Kindle. Book excerpt: The brain's ability to process information crucially relies on connectivity. Understanding how the brain processes complex information and how such abilities are disrupted in individuals with neuropsychological disorders will require an improved understanding of brain connectivity. Autism is an intriguingly complex neurodevelopmental disorder with multidimensional symptoms and cognitive characteristics. A biological origin for autism spectrum disorders (ASD) had been proposed even in the earliest published accounts (Kanner, 1943; Asperger, 1944). Despite decades of research, a focal neurobiological marker for autism has been elusive. Nevertheless, disruptions in interregional and functional and anatomical connectivity have been a hallmark of neural functioning in ASD. Theoretical accounts of connectivity perceive ASD as a cognitive and neurobiological disorder associated with altered functioning of integrative circuitry. Neuroimaging studies have reported disruptions in functional connectivity (synchronization of activated brain areas) during cognitive tasks and during task-free resting states. While these insights are valuable, they do not address the time-lagged causality and directionality of such correlations. Despite the general promise of the connectivity account of ASD, inconsistencies and methodological differences among studies call for more thorough investigations. A comprehensive neurological account of ASD should incorporate functional, effective, and anatomical connectivity measures and test the diagnostic utility of such measures. In addition, questions pertaining to how cognitive and behavioral intervention can target connection abnormalities in ASD should be addressed. This research topic of the Frontiers in Human Neuroscience addresses “Brain Connectivity in Autism” primarily from cognitive neuroscience and neuroimaging perspectives.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years Autism Spectrum Disorders (ASD) have been considered as resulting from altered connectivity between regions, which may explain characteristic manifestations in socio-emotional function, communication and repetitive behaviour observed clinically. This thesis aims to provide evidence for altered anatomy of networks in ASD. The first step consisted in the creation of a diffusion tensor tractography atlas of the normal human brain derived from 40 healthy adults. The atlas was then used to localise the findings from a meta-analysis of published voxel-based morphometry studies investigating white matter abnormalities in ASD. This analysis showed that patients with ASD display abnormalities in long white matter association tracts, such as the arcuate and uncinate fasciculus, known to be important for language and social cognition. A second step consisted in the tractography analysis of limbic and cerebellar tracts in a small pilot study. Our findings confirmed differences in the the uncinate tract in ASD and in addition we found differences in the cingulum and major intracecebellar and cerebellar output tract. Finally, Tract-Based Spatial Statistics (TBSS) and tractography analysis of a multi-centre, case-control study was performed on 61 individuals with ASD and 61 controls. Differences in the frontal connections of the arcuate fasciculus, uncinate fasciculus, cingulum and corpus callosum were found. Tract specific measurements in the arcuate and uncinate were associated with a history of delayed echolalia and impaired used efface expression in childhood, respectively. In conclusion these series of studies show that ASD are associated with specific structural abnormalities of the limbic, language and interhemispheric white matter fibres. Differences in white matter anatomy were localised in major connections to the frontal lobe and associated with specific autistic features and traits in chilldhood.

Download or read book Brain Connectivity Changes Associated with One Year of Behavioral Therapy for Young Children with Autism Spectrum Disorder ASD written by Hailey Michelle Ormand and published by . This book was released on 2013 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although much of the current literature in autism spectrum disorders (ASD) has focused on illuminating their biological underpinnings or identifying effective treatment approaches, very little research has integrated these two areas of study and examined the neurobiological outcomes associated with various autism interventions. The proposed study will use functional connectivity magnetic resonance imaging (fcMRI) to measure changes in resting state connectivity associated with an intensive behavioral intervention for young children with ASD. Independent component analysis and t-tests will be used to determine if 20 children receiving a behavioral intervention experience greater changes in connectivity than 20 children (matched for sex and developmental age) in a control group receiving treatment as usual (TAU).

Book excerpt: The Neuroscience of Autism provides a comprehensive accounting of autism spectrum disorders by integrating scientific findings from behavioral, cognitive and neurobiological research. The book begins by defining autism, identifying characteristics and prevalence, exploring its history, and then moving on to the cognitive and social bases of behavioral symptoms, the brain bases of behavioral and cognitive symptoms, and finally, intervention practices. It examines theoretical models such as weak central coherence, enhanced perceptual functioning, and the extreme male brain hypothesis. Finally, the book addresses the increased attention on the brain connectivity model of autism, looking at the synchronization of brain activity across different brain areas, the causal influence of a brain region on another, and white matter cable connections in the brain. - Delves into the increasing prevalence of autism in the United States - Focuses on screening tools for early identification - Discusses the neuroanatomical differences seen in individuals with autism - Examines the inferences gained from functional MRI studies of autism
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 Advanced Neuroimaging Methods for Studying Autism Disorder written by Alessandro Grecucci and published by Frontiers Media SA. This book was released on 2017-11-16 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last twenty years, many attempts have been made to provide neurobiological models of autism. Functional, structural and connectivity analyses have highlighted reduced responses in key social areas, such as amygdala, medial prefrontal cortex, cingulate cortex, and superior temporal sulcus. However, these studies present discrepant results and some of them have been questioned for methodological limitations. The aim of this research topic is to present advanced neuroimaging methods able to capture the complexity of the neural deficits displayed in autism. This special issue presents new studies using structural and functional MRI, as well as magnetoencephalography, and novel protocols to analyze data (Analysis of Cluster Variability, Noise Reduction Strategies, Source-based Morphometry, Functional Connectivity Density, Restriction Spectrum Imaging and the others). We believe it is time to integrate data provided by different techniques and methodologies in order to have a better understanding of autism.

Download or read book Imaging the Brain in Autism written by Manuel F. Casanova and published by Springer Science & Business Media. This book was released on 2013-05-24 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data compiled by the Center for Disease Control and Prevention indicates an alarming and continuing increase in the prevalence of autism. Despite intensive research during the last few decades, autism remains a behavioral defined syndrome wherein diagnostic criteria lack in construct validity. And, contrary to other conditions like diabetes and hypertension, there are no biomarkers for autism. However, new imaging methods are changing the way we think about autism, bringing us closer to a falsifiable definition for the condition, identifying affected individuals earlier in life, and recognizing different subtypes of autism. The imaging modalities discussed in this book emphasize the power of new technology to uncover important clues about the condition with the hope of developing effective interventions. Imaging the Brain in Autism was created to examine autism from a unique perspective that would emphasize results from different imaging technologies. These techniques show brain abnormalities in a significant percentage of patients, abnormalities that translate into aberrant functioning and significant clinical symptomatology. It is our hope that this newfound understanding will make the field work collaborative and provide a path that minimizes technical impediments.
Download or read book Brain Network Dysfunction in Neuropsychiatric Illness written by Vaibhav A. Diwadkar and published by Springer Nature. This book was released on 2021-05-11 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brain network function and dysfunction is the dominant model for understanding how the brain gives rise to normal and abnormal behavior. Moreover, neuropsychiatric illnesses continue to resist attempts to reveal an understanding of their bases. Thus, this timely volume provides a synthesis of the uses of multiple analytic methods as they are applied to neuroimaging data, to seek understanding of the neurobiological bases of psychiatric illnesses, understanding that can subsequently aid in their management and treatment. A principle focus is on the analyses and application of methods to functional magnetic resonance imaging (fMRI) data. fMRI remains the most widely used neuroimaging technique for estimating brain network function, and several of the methods covered can estimate brain network dysfunction in resting and task-active states. Additional chapters provide details on how these methods are (and can be) applied in the understanding of several neuropsychiatric disorders, including schizophrenia, mood disorders, autism, borderline personality disorder, and attention deficit hyperactivity disorder (ADHD). A final complement of chapters provides a collective overview of how this framework continues to provoke theoretical advances in our conception of the brain in psychiatry. This unique volume is designed to be a comprehensive resource for imaging researchers interested in psychiatry, and for psychiatrists interested in advanced imaging applications.

Download or read book Movement Control written by Paul Cordo and published by Cambridge University Press. This book was released on 1994-05-27 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Movement is arguably the most fundamental and important function of the nervous system. Purposive movement requires the coordination of actions within many areas of the cerebral cortex, cerebellum, basal ganglia, spinal cord, and peripheral nerves and sensory receptors, which together must control a highly complex biomechanical apparatus made up of the skeleton and muscles. Beginning at the level of biomechanics and spinal reflexes and proceeding upward to brain structures in the cerebellum, brainstem and cerebral cortex, the chapters in this book highlight the important issues in movement control. Commentaries provide a balanced treatment of the articles that have been written by experts in a variety of areas concerned with movement, including behaviour, physiology, robotics, and mathematics.

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.
