Fragile X syndrome is one of the main causes of child developmental delay and autism spectrum disorders. A premutated form of the same gene is also the basis for neurological disabilities in adults. This book breaks down the complex science of this genetic disorder and provides the facts and advice that every bewildered parent or professional needs to support individuals with Fragile X syndrome. This handbook offers a straightforward introduction that clearly explains the condition on both a scientific and practical level. With sections on diagnosis, symptoms and treatment, as well as discussions of various emotional and behavioral considerations, the book covers all aspects Fragile X syndrome, its implications, and the possibilities open to families affected by it. The book demonstrates how with the right therapies progress can be made and emphasizes how music can be used effectively to promote communication, interaction, fine motor skills and responsiveness in children with the condition. This is an essential reference tool for families of individuals with Fragile X syndrome, as well as therapists and healthcare professionals who are unfamiliar with the condition and looking to find out more.

This new book is an up-to-date review of the clinical, epidemiological, and cytogenetic aspects of the fragile X (Martin-Bell) syndrome--the most common genetic cause of mental retardation after Down syndrome. The book includes the latest research findings concerning diagnosis on the basis of the appearance of a fragile site in cultured lymphocytes. It assumes little prior knowledge of the subject, and provides a clearly written, easy-to-understand discussion previously unavailable in a single reference source. The book will be of special interest to molecular biologists, cytogeneticists, medical geneticists, and clinicians and other professionals working with the mentally handicapped.

Fragile X syndrome is an inherited disease caused by an excessive length of the FMR protein due to mutations in the FMR1 gene located on the X chromosome. It is commonly described as one of the most common genetic diseases with autism-like behaviours and related developmental disabilities. Beside intellectual delays, behavioural problems, and communication difficulties, mood disorders usually occur. Diagnosis is based on laboratory tests and DNA results. Phenotypes including long and narrow face, large ears, hyper-arched palate, flat feet, ataxia, seizures, anxiety, aggression, and hand-related stereotypic behaviours are frequently observed. Although there is no specific cure, early interventions are highly encouraging, promising, and recommended. Pharmacological treatments may be combined with behavioural and/or cognitive behavioural interventions. Recently, assistive technology-based programs have been implemented. This volume includes seven chapters and addresses the newest advances in the diagnosis and treatment of individuals with Fragile X syndrome. Chapter One encompasses the molecular features and pathological bases of the disease. A comprehensive literature overview was conducted. The role of the FMR protein was emphasized although few studies evaluated its function. Chapter Two deals with the neuropsychiatric symptoms related to the syndrome. A complete conceptual framework was exhaustively detailed. Chapter Three emphasizes the role of pharmacotherapy in the treatment of Fragile X syndrome. A further literature review was carried out. Clinical relevance was outlined. Chapter Four provides the reader with a conceptual analysis. Besides molecular features, brain development was described. Challenging behaviours were included and the importance of the early combined intervention was critically discussed. Chapters Five, Six, and Seven detailed three case reports on the effectiveness and the suitability of assistive technology-based interventions. Specifically, Chapter Five argued for microswitch-cluster technology focused on pursuing the dual simultaneous goal of promoting an adaptive response (i.e., object manipulation) and reducing a challenging behaviour (i.e., hand mouthing). Chapter Six describes a combined microswitch and VOCA program useful to ensure the participant has the choice between independent access to positive stimulation and asking for social interaction. Finally, Chapter Seven includes choice opportunities through an assistive technology-mediated program involving a boy with Fragile X in a functional task. Targeted readers (i.e., caregivers, clinicians, speech therapists, professionals, psychologists, neurologists, parents of children with Fragile X syndrome, teachers) may find interesting and stimulating tips and insights for daily use in clinical research and practice, with the dual objective of diagnosis and treatment.

Expanded and revised, this unique book provides concise descriptions of the many causes of epilepsy, for use in clinical practice.

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

A tiny mutation on the X chromosome can shape a family’s history. Passed down from a “carrier” parent to a child, fragile X syndrome is the most common inherited cause of intellectual disability and autism. Beyond that—and a rarity among genetic disorders—some fragile X carriers not only transmit the mutation but also experience related conditions themselves. In such cases, carriers can have tremors, infertility, and psychiatric disorders that complicate raising children with fragile X syndrome—and all too often, they suffer in silence. The Carriers investigates this common but still little-known genetic condition and its life-altering consequences. Anne Skomorowsky reveals how this disorder afflicts families across generations, telling the stories of the mothers and grandparents of fragile X patients and considering how genes interact with family dynamics. She interweaves the personal narratives and family histories of the people affected by fragile X disorders with clear and accessible explanations of the science behind them. Skomorowsky unpacks the latest research on the fragile X mutation and explores the history of its discovery. She highlights the roles of women as carriers, caregivers, and researchers who have made astonishing scientific breakthroughs over the last three decades. The Carriers is an essential book for fragile X families, including those just learning they are carriers, and for all readers interested in the complexities of heredity, the ethical dilemmas of genetic medicine, and the relationship between genes and personality.
