Book Description
Experiences during early life program the central nervous- and endocrine-systems with consequences for susceptibility to physical and mental disorders. These programming effects depend on genetic and epigenetic factors, and their outcome leads to an adaptive or maladaptive phenotype to a given later environmental context. This Research Topic focused on the hypothalamus-pituitary-adrenal (HPA)-axis and stress-related phenotypes, and on how HPA-axis programming by the environment precisely occurs. We included original research, mini-review and review papers on a broad range of topics related to HPA-axis programming.

Book Description
This open access book sets out the stress-system model for functional somatic symptoms in children and adolescents. The book begins by exploring the initial encounter between the paediatrician, child, and family, moves through the assessment process, including the formulation and the treatment contract, and then describes the various forms of treatment that are designed to settle the child’s dysregulated stress system. This approach both provides a new understanding of how such symptoms emerge – typically, through a history of recurrent or chronic stress, either physical or psychological – and points the way to effective assessment, management, and treatment that put the child (and family) back on the road to health and well-being.

Book Description
This book reviews all important aspects of anxiety disorders with the aim of shedding new light on these disorders through combined understanding of traditional and novel paradigms. The book is divided into five sections, the first of which reinterprets anxiety from a network science perspective, examining the altered topological properties of brain networks in anxiety disorders. The second section discusses recent advances in understanding of the neurobiology of anxiety disorders, covering, for example, gene-environmental interactions and the roles of neurotransmitter systems and the oxytocin system. A wide range of diagnostic and clinical issues in anxiety disorders are then addressed, before turning attention to contemporary treatment approaches in the context of novel bio-psychosocial-behavioral models, including bio- and neurofeedback, cognitive behavioral therapy, neurostimulation, virtual reality exposure therapy, pharmacological interventions, psychodynamic therapy, and CAM options. The final section is devoted to precision psychiatry in anxiety disorders, an increasingly important area as we move toward personalized treatment. Anxiety Disorders will be of interest for all researchers and clinicians in the field.

Book Description
Epigenetics is defined as heritable changes that do not affect the DNA sequence but influence gene expression. Epigenetic changes occur at the levels of DNA, histone, protein, and chromatin structures. Proper epigenetic modifications are essential for cell differentiation and function during development, while some epigenetic modifications are passed on from parents to offspring through gametes. Therefore, alterations of epigenetic states would have serious consequences for human development and health. This realization and the advent of new technologies have encouraged the advance of epigenetic studies in recent years. Nonetheless, many aspects of epigenetics, such as regulatory mechanisms and evolutional advantages, remain to be better understood.Written by 26 scientists at the forefront of epigenetics research, this book discusses the different facets of epigenetics: from gametogenesis to child development, as well as from mechanistic studies in animal models to reviews of human clinical data.

Book Description
Anxiety affects millions, manifesting as generalized anxiety disorder (GAD), obsessive compulsive disorder, panic disorder, phobias, post-traumatic-stress disorder (PTSD), and social anxiety disorder. Not only are anxiety disorders common, but they are also crippling, frequently co-occurring and predict high risk for depressive disorders. Shared mechanisms may explain the overlapping features of many anxiety disorders and account for associations with other highly-impairing conditions, such as major depression and substance use. Beyond risk for specific disorders, anxiety also predicts a number of other adverse outcomes, including suicidal behavior, medical problems, social, and economic difficulties. Conversely, disorder-specific mechanisms may also exist and explain the unique features of each syndrome. Thus, it is important to understand both shared and specific aspects of anxiety. The Primer on Anxiety Disorders provides early-stage practitioners and trainees, as well as seasoned clinicians and researchers, with need-to-know knowledge on diagnosis and treatment. Clinical cases are used throughout the book to enhance understanding of and illustrate specific disorders, comorbid conditions and clinical issues. To facilitate an integrative approach, content allows clinicians to understand patient characteristics and tailor interventions. The integrated approach of each chapter includes recent research on genetics and neuroscience to understand the mechanisms of anxiety disorders, focusing on the forthcoming new nosology in DSM-5. Chapters further integrate innovative advances in clinical research providing research on a range of discoveries regarding biomarkers of illness, biological predictors of treatments and the effect of treatment on neurocircuitry.

Book Description
By stimulating adrenal gland and corticosteroid synthesis, the adrenocorticotropic hormone (ACTH) plays a central role in response to stress. In this Research Topic, a particular attention has been given to the recent developments on adrenocortical zonation; the growth-promoting activities of ACTH; the various steps involved in acute and chronic regulation of steroid secretion by ACTH, including the effect of ACTH on circadian rhythms of glucocorticoid secretion. The Research Topic also reviews progress and challenges surrounding the properties of ACTH binding to the MC2 receptor (MC2R), including the importance of melanocortin-2 receptor accessory protein (MRAP) in MC2R expression and function, the various intracellular signaling cascades, which involve not only protein kinase A, the key mediator of ACTH action, but also phosphatases, phosphodiesterases, ion channels and the cytoskeleton. The importance of the proteins involved in the cell detoxification is also considered, in particular the effect that ACTH has on protection against reactive oxygen species generated during steroidogenesis. The impact of the cellular microenvironment, including local production of ACTH is discussed, both as an important factor in the maintenance of homeostasis, but also in pathological situations, such as severe inflammation. Finally, the Research Topic reviews the role that the pituitary-adrenal axis may have in the development of metabolic disorders. In addition to mutations or alterations of expression of genes encoding components of the steroidogenesis and signaling pathways, chronic stress and sleep disturbance are both associated with hyperactivity of the adrenal gland. A resulting effect is increased glucocorticoid secretion inducing food intake and weight gain, which, in turn, leads to insulin and leptin resistance. These aspects are described in detail in this Research Topic by key investigators in the field. Many of the aspects addressed in this Research Topic still represent a stimulus for future studies, their outcome aimed at providing evidence of the central position occupied by the adrenal cortex in many metabolic functions when its homeostasis is disrupted. An in-depth investigation of the mechanisms underlying these pathways will be invaluable in developing new therapeutic tools and strategies.

Book Description
Less than twenty years ago the field of mental health did not have the language to describe the long-term consequences of traumatic stress. In the absence of specific biological markers, the psychological symptoms of trauma survivors were often attributed to neurotic or even psychotic disorders. But in 1980, after more than a century of clinical observations, post-traumatic stress disorder (PTSD) was recognized as a diagnosis. By the 1990s, biological findings began to provide objective validation that PTSD is more than a politically or socially motivated conceptualization of human suffering. This volume summarizes the latest findings in this rapidly changing field, including the biological differences between PTSD, stress, and other psychiatric disorders Chief among the findings is that PTSD is a different disorder than was originally thought, and that the biology of PTSD is not simply the biology of stress. Topics include the empirical basis for post-traumatic stress disorder; psychobiological findings; neurodevelopmental effects of trauma; neurological basis of traumatic and non-traumatic memory impairment in post-traumatic stress disorder; how basic research informs clinical observations; and the psychobiology of treatment.

Book Description
This third edition of Child Psychology continues the tradition of showcasing cutting-edge research in the field of developmental science, including individual differences, dynamic systems and processes, and contexts of development. While retaining a similar structure to the last edition, this revision consists of completely new content with updated programmatic research and contemporary research trends and interests. The first three sections highlight research that is organized chronologically by age: Infancy, Childhood, and Adolescence. Within each section, individual chapters address contemporary research on a specific area of development, such as learning, cognition, social, and emotional development at that period in childhood. The fourth section, Ecological Influences, emphasizes contextual influences relevant to children of all ages, including risk and protective processes, family and neighborhood context, race and ethnicity, peer relations, the effects of poverty, and the impact of the digital world. Child Psychology also features a unique focus on four progressive themes. First, emphasis is placed on theory and explanation—the "why and how" of the developmental process. Second, explanations of a transactional and multidimensional nature of development are at the forefront of all chapters. Third, the multi-faceted approach to development highlights contextual influences and cultural diversity among children from different communities and backgrounds. Finally, methodological innovation is a key concern, and research tools presented across chapters span the full array available to developmental scientists who focus on different systems and levels of analysis. The thoroughness and depth of this book, in addition to its methodological rigor, make it an ideal handbook for researchers, practitioners, policy makers, and advanced students across a range of disciplines, including psychology, education, economics and public policy.
