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.

This book explains in detail the diagnosis, management, and treatment of comorbid disorders in patients with autism spectrum disorders (ASD). Important insights are provided into the nature of the symptoms of psychiatric comorbidities in these patients, and particularly children and adolescents, with a view to assisting clinicians in reaching a correct diagnosis that will permit the implementation of appropriate treatment strategies, whether psychological or pharmacological. The full range of potential comorbidities is considered, including mood disorders, anxiety disorders, obsessive-compulsive disorder, schizophrenia spectrum and other psychotic disorders, eating disorders, disruptive behavioral disorders, Tourette’s disorder, and substance-related disorders. In each case guidance is provided on how to avoid incorrectly attributing symptoms to ASD and on treatment options. Psychiatric Comorbidities in Autism Spectrum Disorders will be of value to all practitioners who are confronted by patients with these complex co-occurring conditions.

Autism Spectrum Disorder of the Pittsburgh Pocket Psychiatry Series highlights current key topics for this developmental neurobiological disorder: early identification and diagnosis; medical, psychiatric, behavioral, social, educational and language evaluations and treatment approaches; genetics and neurobiology; and transition-age and adult services. This book incorporates practical clinical knowledge within a didactic framework to provide a comprehensive overview of Autism Spectrum Disorder (ASD) across the lifespan.

Intellectual Disability (ID) describes a lifelong condition of heterogeneous aetiology, associated with the impairment of intellectual functioning (IQ 70), significant impairment of adaptive skills, and onset before the age of 18 years. People with ID experience significant physical andmental health problems like associated sensory/motor impairments and epilepsy, some of which are contributed to by underlying primary causes. Psychiatric problems are also three times more common in people with ID in comparison to the general population.The psychiatry of ID is a core part of training to be a psychiatrist yet there are limited resources on this topic aimed at both trainees and practising clinicians alike. Oxford Textbook of the Psychiatry of Intellectual Disability bridges this gap by providing up-to-date evidence-based content onthe assessment, diagnosis, and management of psychiatry in people with ID.Featuring 28 chapters written by international experts in the field, the Oxford Textbook of the Psychiatry of Intellectual Disability presents fresh global insight and coverage of the subject. Chapters cover key topics from the developmental aspects of ID, mental disorders in childhood, andbehaviour phenotypes, through to physical health, dementia and other disorders associated with ageing.Each chapter provides trustworthy evidence and a wealth of practical advice for clinical situations, including case studies in community and hospital settings, and multiple choice questions for self-evaluation and consolidation of knowledge.

"Although cases of autism can, in retrospect, be identified before Kanner's 1943 classic report (also see Donvan and Zucker 2016), it was Kanner's genius to put together the core features that we continue to associate with autism; autistic aloneness and restricted interests/difficulties with change. This description was straightforward and atheoretical and has stood the test of time even as we debate the boundaries of autism today. The early years following Kanner's initial presentation were plagued by a lack of consistency in diagnosis and several mistaken beliefs about autism, e.g., associations with childhood schizophrenia and inappropriate parenting. This changed dramatically in the 1970s as three lines of evidence helped establish the validity of autism as a diagnostic concept: These included: 1) the awareness that autism was a brain-based disorder associated with high rates of epilepsy with peaks of onset in early childhood and adolescence, 2) the first twin studies of autism made it clear that there was a very strong genetic component of autism with high concordance in MZ twins, and 3) children with autism responded best to structured teaching rather than unstructured psychotherapy (see Jackson and Volkmar, 2019 for a discussion)"--
