Autism Spectrum Disorders


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.




Clinician’s Manual on Autism Spectrum Disorder


Book Description

This concise, yet practical handbook will aid in supporting the diagnosis, treatment, and long-term management of autism, including behavioral therapies, current clinical trials, and emerging pharmaceutical treatments. Autism spectrum disorder (ASD) is a developmental disorder characterised by disturbance in language, perception, and social skills that affects an estimated 1–2 per 1,000 people worldwide (although the number is as high as 20 per 1000 in the US). While studies have suggested a disturbance in neural metabolism in patients with ADS, the exact cause of the ASD still remains unknown. In 2013, a single indication of ASD, which united several related conditions (ie, classical autism, Asperger’s syndrome, Fragile X Syndrome, Landau-Kleffner Syndrome, Rett syndrome, childhood disintegrative disorder, and PDD-NOS), was included in the fifth edition of the Diagnostic and Statistical Manual of Mood Disorders for the first time in order to support more standardized diagnoses.







Comorbid Conditions Among Children with Autism Spectrum Disorders


Book Description

This book presents the similarities and intersections between Autism Spectrum Disorders and comorbid conditions in children.

It addresses the strengths and limitations of age-appropriate assessment measures as well as activity and motor skill measurement methods. Specific comorbid disorders are examined through the review of core symptoms, prognostic and diagnostic issues and treatment options for children on the ASD spectrum. Featured topics include: Challenging behaviors in children with ASD. Conditions ranging from feeding and gastrointestinal disorders to epilepsy. Developmental coordination disorder (DCD). Intellectual disability (ID). Methods and procedures for measuring comorbid psychological, medical and motor disorders. Comorbid Conditions Among Children with Autism Spectrum Disorders is a must-have resource for researchers, clinicians and professionals and graduate students across such fields as clinical child, school and developmental psychology, child and adolescent psychiatry and social work as well as rehabilitation medicine/therapy, behavioral therapy, pediatrics and educational psychology.

Handbook of Autism Spectrum Disorder and the Law


Book Description

This book addresses an important and relatively neglected topic in the scientific literature: individuals with autism spectrum disorder (ASD) who have dealings with the legal system. It examines issues and implications for autistic people, who have a significant risk for engagement with the legal system in some capacity (e.g., witness/bystander, victim, or perpetrator). Key areas of coverage include: Autistic people as victims and perpetrators of criminal activities, including violence, stalking, sexual exploitation, and cybercrime. Risks for unlawful behavior in individuals with autism and Asperger's. Legal assessment issues, such as witness protection and postconviction diagnoses. Legal outcomes for autistic people, including case law, prevention, service provisions in correctional settings, and rights and support systems. The Handbook of Autism Spectrum Disorder and the Law is an essential, comprehensive resource that explores the risk for unlawful behaviors affecting autistitc people as victims and perpetrators, as well as related issues of assessment and treatment, and outcome. It is a must-have reference for researchers, clinicians/practitioners, and graduate students in psychology, psychiatry, social work, and law, as well as professionals in such related fields, as criminology/criminal justice and the legal system.




The Oxford Handbook of Autism and Co-Occurring Psychiatric Conditions


Book Description

Co-occurring psychiatric conditions are extremely common among people who have autism spectrum disorder (ASD). The Oxford Handbook of Autism and Co-Occurring Psychiatric Conditions presents a compilation of the latest research in this area, summarized by internationally renowned experts. Each chapter presents an overview of the problem or disorder including information on prevalence in ASD and in the general public and a synthesis of the research on etiology, diagnostic best practices, and evidence-based intervention approaches. Case studies bring these concepts to life, and each chapter concludes with suggestions for future research directions in order to further develop our scientific and clinical understanding of the particular comorbidity. Given the fact that comorbidity is often a chronic and pervasive concern, this Handbook takes a lifespan approach, with each chapter touching on developmental aspects of the targeted problem, from early childhood through adulthood. The concluding section of the Handbook is comprised of content on clinical considerations and research approaches, including chapters on medications commonly used to treat co-occurring conditions, strategies for managing crisis situations in this clinical population, and community partnerships within an implementation science framework.




Mental Disorders and Disabilities Among Low-Income Children


Book Description

Children living in poverty are more likely to have mental health problems, and their conditions are more likely to be severe. Of the approximately 1.3 million children who were recipients of Supplemental Security Income (SSI) disability benefits in 2013, about 50% were disabled primarily due to a mental disorder. An increase in the number of children who are recipients of SSI benefits due to mental disorders has been observed through several decades of the program beginning in 1985 and continuing through 2010. Nevertheless, less than 1% of children in the United States are recipients of SSI disability benefits for a mental disorder. At the request of the Social Security Administration, Mental Disorders and Disability Among Low-Income Children compares national trends in the number of children with mental disorders with the trends in the number of children receiving benefits from the SSI program, and describes the possible factors that may contribute to any differences between the two groups. This report provides an overview of the current status of the diagnosis and treatment of mental disorders, and the levels of impairment in the U.S. population under age 18. The report focuses on 6 mental disorders, chosen due to their prevalence and the severity of disability attributed to those disorders within the SSI disability program: attention-deficit/hyperactivity disorder, oppositional defiant disorder/conduct disorder, autism spectrum disorder, intellectual disability, learning disabilities, and mood disorders. While this report is not a comprehensive discussion of these disorders, Mental Disorders and Disability Among Low-Income Children provides the best currently available information regarding demographics, diagnosis, treatment, and expectations for the disorder time course - both the natural course and under treatment.




Neuronal and Synaptic Dysfunction in Autism Spectrum Disorder and Intellectual Disability


Book Description

Neuronal and Synaptic Dysfunction in Autism Spectrum Disorder and Intellectual Disability provides the latest information on Autism spectrum disorders (ASDs), the lifelong neurodevelopmental disorders that present in early childhood and affect how individuals communicate and relate to others and their surroundings. In addition, three quarters of ASD patients also manifest severe intellectual disability. Though certain genes have been implicated, ASDs remain largely a mystery, and research looking into causes and cellular deficits are crucial for better understanding of neurodevelopmental disorders. Despite the prevalence and insidious nature of this disorder, this book remains to be an extensive resource of information and background on the state of current research in the field. The book serves as a reference for this purpose, and discusses the crucial role synaptic activity plays in proper brain function. In addition, the volume discusses the neurodevelopmental synaptopathies and serves as a resource for scientists and clinicians in all biomedical science specialties. This research has been crucial for recent studies that have provided a rationale for the development of pharmacological agents able to counteract functional synaptic anomalies and potentially ameliorate some ASD symptoms. - Introduces the genetic and non-genetic causes of autism and associated intellectual disabilities - Describes the genes implicated in autistic spectrum disorders and their function - Considers major individual genetic causes of autism, Rett syndrome, Fragile X syndrome, and other autism spectrum disorders, as well as their classification as synaptopathies - Presents a thorough discussion of the clinical aspects of multiple neurodevelopmental disorders and the experimental models that exist to study their pathophysiology in vitro and in vivo, including animal models and patient-derived stem cell culture




Psychiatric Symptoms and Comorbidities in Autism Spectrum Disorder
