This book was released on 2010-09-08 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Novel Approaches into the Origins of Neurodevelopmental Disorders: The Fetal Physiology Foundation Over the past two decades, autism, a neurodevelopmental disorder that is defined by behavior and was once believed to be rare, became recognized in increasing numbers of children and recently received distinction as an “epidemic” [1]. While numbers of affected children have steadily increased, our knowledge is still ins- ficient to explain autism’s diverse causes and broad range of presentations. Despite remarkable progress in research, available medical diagnostic testing applies only to a small minority of affected children. Thus, scientifically based explanations with which physicians can diagnose and treat the majority of children with autism and advise their parents are quite limited. Our society and scientific community were unprepared for the rise in autism, which explains our present inability to understand most of its causes. Researchers in neurodevelopmental disorders have long been aware of other disorders that, despite extensive efforts, have not yielded clear genetic or environmental origins, and autism has become symbolic of the need for new approaches to research into these complex conditions. Although autism has captured our attention in recent years, the prevalence of other neurodevelopmental disorders such as attention de- cit hyperactivity disorder (ADHD) and bipolar disorder, among others, also has been increasing [2–4].
Download or read book Vibrant and Healthy Kids written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2019-12-27 with total page 621 pages. Available in PDF, EPUB and Kindle. Book excerpt: Children are the foundation of the United States, and supporting them is a key component of building a successful future. However, millions of children face health inequities that compromise their development, well-being, and long-term outcomes, despite substantial scientific evidence about how those adversities contribute to poor health. Advancements in neurobiological and socio-behavioral science show that critical biological systems develop in the prenatal through early childhood periods, and neurobiological development is extremely responsive to environmental influences during these stages. Consequently, social, economic, cultural, and environmental factors significantly affect a child's health ecosystem and ability to thrive throughout adulthood. Vibrant and Healthy Kids: Aligning Science, Practice, and Policy to Advance Health Equity builds upon and updates research from Communities in Action: Pathways to Health Equity (2017) and From Neurons to Neighborhoods: The Science of Early Childhood Development (2000). This report provides a brief overview of stressors that affect childhood development and health, a framework for applying current brain and development science to the real world, a roadmap for implementing tailored interventions, and recommendations about improving systems to better align with our understanding of the significant impact of health equity.
Download or read book The Genetics of Neurodevelopmental Disorders written by Kevin J. Mitchell and published by John Wiley & Sons. This book was released on 2015-08-04 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neurodevelopmental disorders arise from disturbances to various processes of brain development, which can manifest in diverse ways. They encompass many rare genetic syndromes as well as common, heritable conditions such as intellectual disability, autism, ADHD, schizophrenia and many types of epilepsy. The Genetics of Neurodevelopmental Disorders examines recent revolutionary advances in our understanding of the genetics of these disorders, exploring both basic discoveries and the translation of new findings into the clinical setting. The book begins by examining the genetic architecture and etiology of neurodevelopmental disorders. It describes the striking recent progress in identifying pathogenic mutations, which are grouped here based on the neurodevelopmental processes impacted. Subsequent chapters consider the use of cellular and animal models to elucidate the cascading consequences of such mutations, from molecular and cellular levels to emergent effects on neural circuits, brain systems and subsequent psychological development. The text concludes by examining the important clinical implications of the recent advances in the field, from recognition of the genetic causes in individual patients to development of new treatments and interventions. A timely synthesis, The Genetics of Neurodevelopmental Disorders is a unique and essential resource for neuroscientists, geneticists, neurologists and psychiatrists and an accessible and up-to-date overview for medical and science students.

Available in PDF, EPUB and Kindle. Book excerpt: Over its two editions, The New Oxford Textbook of Psychiatry has come to be regarded as one of the most popular and trusted standard psychiatry texts among psychiatrists and trainees. Bringing together 146 chapters from the leading figures in the discipline, it presents a comprehensive account of clinical psychiatry, with reference to its scientific basis and to the patient's perspective throughout. The New Oxford Textbook of Psychiatry, Third Edition has been extensively re-structured and streamlined to keep pace with the significant developments that have taken place in the fields of clinical psychiatry and neuroscience since publication of the second edition in 2009. The new edition has been updated throughout to include the most recent versions of the two main classification systems—-the DSM-5 and the ICD-11—-used throughout the world for the diagnosis of mental disorders. In the years since publication of the first edition, many new and exciting discoveries have occurred in the biological sciences, which are having a major impact on how we study and practise psychiatry. In addition, psychiatry has fostered closer ties with philosophy, and these are leading to healthy discussions about how we should diagnose and treat mental illness. This new edition recognises these and other developments. Throughout, accounts of clinical practice are linked to the underlying science, and to the evidence for the efficacy of treatments. Physical and psychological treatments, including psychodynamic approaches, are covered in depth. The history of psychiatry, ethics, public health aspects, and public attitudes to psychiatry and to patients are all given due attention.

Download or read book Genetics and Epigenetics of Fetal Alcohol Spectrum Disorders written by Feng C. Zhou and published by Frontiers Media SA. This book was released on 2015-08-06 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Women drinking during pregnancy can result in Fetal Alcohol Spectrum Disorder (FASD), which may feature variable neurodevelopmental deficits, facial dysmorphology, growth retardation, and learning disabilities. Research suggests the human brain is precisely formed through an intrinsic, genetic-cellular expression that is carefully orchestrated by an epigenetic program. This program can be influenced by environmental inputs such as alcohol. Current research suggests the genetic and epigenetic elements of FASD are heavily intertwined and highly dependent on one another. As such, now is the time for investigators to combine genetic, genomic and epigenetic components of alcohol research into a centralized, accessible platform for discussion. Genetic analyses inform gene sets which may be vulnerable to alcohol exposure during early neurulation. Prenatal alcohol exposure indeed alters expression of gene subsets, including genes involved in neural specification, hematopoiesis, methylation, chromatin remodeling, histone variants, eye and heart development. Recently, quantitative genomic mapping has revealed loci (QTLs) that mediate alcohol-induced phenotypes identified between two alcohol-drinking mouse strains. One question to consider is (besides the role of dose and stage of alcohol exposure) why only 5% of drinking women deliver newborns diagnosed with FAS (Fetal Alcohol Syndrome)? Studies are ongoing to answer this question by characterizing genome-wide expression, allele-specific expression (ASE), gene polymorphisms (SNPs) and maternal genetic factors that influence alcohol vulnerability. Alcohol exposure during pregnancy, which can lead to FASD, has been used as a model to resolve the epigenetic pathway between environment and phenotype. Epigenetic mechanisms modify genetic outputs through alteration of 3D chromatin structure and accessibility of transcriptional machinery. Several laboratories have reported altered epigenetics, including DNA methylation and histone modification, in multiple models of FASD. During development DNA methylation is dynamic yet orchestrated in a precise spatiotemporal manner during neurulation and coincidental with neural differentiation. Alcohol can directly influence epigenetics through alterations of the methionine pathway and subsequent DNA or histone methylation/acetylation. Alcohol also alters noncoding RNA including miRNA and transposable elements (TEs). Evidence suggests that miRNA expression may mediate ethanol teratology, and TEs may be affected by alcohol through the alteration of DNA methylation at its regulatory region. In this manner, the epigenetic and genetic components of FASD are revealing themselves to be mechanistically intertwined. Can alcohol-induced epigenomic alterations be passed across generations? Early epidemiological studies have revealed infants with FASD-like features in the absence of maternal alcohol, where the fathers were alcoholics. Novel mechanisms for alcohol-induced phenotypes include altered sperm DNA methylation, hypomethylated paternal allele and heritable epimutations. These studies predict the heritability of alcohol-induced epigenetic abnormalities and gene functionality across generations. We opened a forum to researchers and investigators the field of FASD to discuss their insights, hypotheses, fresh data, past research, and future research themes embedded in this rising field of the genetics and epigenetics of FASD. This eBook is a product of the collective sharing and debate among researchers who have contributed or reviewed each subject.

Download or read book Deciphering serotonin s role in neurodevelopment written by Dirk Schubert and published by Frontiers E-books. This book was released on 2014-10-03 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most challenging questions in neurobiology to tackle is how the serotonergic system steers neurodevelopment. With the increase in serotonergic anxiolytic and antidepressant drugs, serotonin was thought to signal adversity or to serve as an emotional signal. However, a vast amount of literature is accumulating showing that serotonin rather mediates neuroplasticity and plays a key role in early developmental processes. For instance, selective serotonin reuptake inhibitors (SSRIs), serving as antidepressants, increase neurogenesis and trigger autism-related brain and behavioural changes during embryonic and perinatal exposure. Moreover, serotonin transporter gene variation is associated with alterations in corticolimbic neuroplasticity, autism-related neuroanatomical changes, as well alterations in social behaviour. Hence, the view is emerging that early life changes in serotonin levels influence the developmental course of socio-emotional brain circuits that are relevant for autism and other neurodevelopmental disorders. It is particularly exciting that the effects of embryonic and perinatal SSRI exposure and serotonin transporter gene variation on neurodevelopment seem to overlap to a large extent, at the cellular as well as the behavioural level. Yet, the precise mechanisms by which serotonin mediates neurodevelopment in the normal and ´autistic´ brain is unclear. Whereas serotonin has a placental origin during early gestation, serotonergic neurons develop during midgestation under the control of a cascade of transcription factors determining the fate of mid-hindbrain neurons that together for the Raphe nuclei. These neurons are among the earliest neurons to be generated, and because serotonin is released before any conventional synapses are formed, serotonin is suspected to influence crucial neurodevelopmental processes such as proliferation,migration and network formation. During late gestation they target their final destinations in, for instance, the cortex, where they affect the secretion of reelin. Reelin is a secreted extracellular matrix glycoprotein that helps to regulate processes of neuronal migration and positioning in the developing cortex by controlling cell–cell interactions. During the late prenatal and early postnatal phase (in rodents) serotonin further shapes the outgrowth of projecting neurons, synaptic connectivity, and the morphology of white fiber tracts. This is under the influence of transient serotonin transporter expression in (thalamo)cortical projections, sensory and prefrontal cortices and the hippocampus, as well as the local expression patterns of 5-HT1A, 5-HT1B and 5-HT3A receptors that each exert their specific roles in neuronal migration, remodeling of axons, and controlling dendritic complexity. There is also evidence that serotonin influences neural activity in locus ceroeleus neurons. Hence, serotonin appears to influence the development of both short- and long-distance connections in the brain. This Research Topic is devoted to studies pinpointing the neurodevelopmental effects of serotonin in relation to prenatal SSRI exposure, serotonin transporter gene variation, and autism/neurodevelopmental disorders, using a wide-variety of cellular and molecular neurobiological techniques like, (epi)genetics, knockout, knockdown, neuroanatomy, physiology, MRI and behaviour in rodents and humans. We especially encouraged attempts to cross-link the neurodevelopmental processes across the fields of prenatal SSRI exposure, serotonin transporter gene variation, and autism/neurodevelopmental disorders, as well as new views on the positive or beneficial effects on serotonin-mediated neurodevelopmental changes.
Download or read book From Neurons to Neighborhoods written by National Research Council and published by National Academies Press. This book was released on 2000-11-13 with total page 610 pages. Available in PDF, EPUB and Kindle. Book excerpt: How we raise young children is one of today's most highly personalized and sharply politicized issues, in part because each of us can claim some level of "expertise." The debate has intensified as discoveries about our development-in the womb and in the first months and years-have reached the popular media. How can we use our burgeoning knowledge to assure the well-being of all young children, for their own sake as well as for the sake of our nation? Drawing from new findings, this book presents important conclusions about nature-versus-nurture, the impact of being born into a working family, the effect of politics on programs for children, the costs and benefits of intervention, and other issues. The committee issues a series of challenges to decision makers regarding the quality of child care, issues of racial and ethnic diversity, the integration of children's cognitive and emotional development, and more. Authoritative yet accessible, From Neurons to Neighborhoods presents the evidence about "brain wiring" and how kids learn to speak, think, and regulate their behavior. It examines the effect of the climate-family, child care, community-within which the child grows.

Available in PDF, EPUB and Kindle. Book excerpt: Epigenetics is considered by many to be the "new genetics" because of the overwhelming evidence of the contribution of non-genetic factors such as nutrition, environment, and chemical exposure on gene expression. The effects of epigenetics are vast, including tissue/organ regeneration, X-chromosome inactivation, and stem cell differentiation and genomic imprinting and aging. Aberrations of epigenetics influence many diseases for which clinical intervention is already in place, and many novel epigenetic therapies for cancer, immune disorders, neurological and metabolic disorders, and imprinting diseases are on the horizon. This comprehensive collection of reviews written by leaders in the field of epigenetics provides a broad view of this important and evolving topic. From molecular mechanisms and epigenetic technology to discoveries in human disease and clinical epigenetics, the nature and applications of the science will be presented for those with interests ranging from the fundamental basis of epigenetics to therapeutic interventions for epigenetic-based disorders. Contributions by leading international investigators involved in molecular research and clinical and therapeutic applications Integrates methods and biological topics with basic and clinical discoveries Includes coverage of new topics in epigenetics such as prions, regulation of long-term memory by epigenetics, metabolic aspects of epigenetics, and epigenetics of neuronal disorders
