The Neurobiological Basis of Suicide


Book Description

With recent studies using genetic, epigenetic, and other molecular and neurochemical approaches, a new era has begun in understanding pathophysiology of suicide. Emerging evidence suggests that neurobiological factors are not only critical in providing potential risk factors but also provide a promising approach to develop more effective treatment and prevention strategies. The Neurobiological Basis of Suicide discusses the most recent findings in suicide neurobiology. Psychological, psychosocial, and cultural factors are important in determining the risk factors for suicide; however, they offer weak prediction and can be of little clinical use. Interestingly, cognitive characteristics are different among depressed suicidal and depressed nonsuicidal subjects, and could be involved in the development of suicidal behavior. The characterization of the neurobiological basis of suicide is in delineating the risk factors associated with suicide. The Neurobiological Basis of Suicide focuses on how and why these neurobiological factors are crucial in the pathogenic mechanisms of suicidal behavior and how these findings can be transformed into potential therapeutic applications.




Behavioral Models in Stress Research


Book Description

Stress is an adaptive response that has developed throughout evolution, and is associated with multiple changes in the biochemistry, histology and physiology of an organism. As stress may induce or contribute to multiple neuropsychiatric disorders, the rigorous investigation of the neural substrates of stress has become a critical endeavour of contemporary biomedical science. This book explores the physiological responses that researchers have attempted to assess in stress-evoked behavioural changes, using both human and animal "experimental" models in clinical and non-clinical research. Though all aspects of the field have their challenges, animal experimental research of stress is a particularly difficult but meaningful task. This book provides succinct and relevant summaries of progress in the area of assessing stress response and the conditions contributing to it.




Depression in Parents, Parenting, and Children


Book Description

Depression is a widespread condition affecting approximately 7.5 million parents in the U.S. each year and may be putting at least 15 million children at risk for adverse health outcomes. Based on evidentiary studies, major depression in either parent can interfere with parenting quality and increase the risk of children developing mental, behavioral and social problems. Depression in Parents, Parenting, and Children highlights disparities in the prevalence, identification, treatment, and prevention of parental depression among different sociodemographic populations. It also outlines strategies for effective intervention and identifies the need for a more interdisciplinary approach that takes biological, psychological, behavioral, interpersonal, and social contexts into consideration. A major challenge to the effective management of parental depression is developing a treatment and prevention strategy that can be introduced within a two-generation framework, conducive for parents and their children. Thus far, both the federal and state response to the problem has been fragmented, poorly funded, and lacking proper oversight. This study examines options for widespread implementation of best practices as well as strategies that can be effective in diverse service settings for diverse populations of children and their families. The delivery of adequate screening and successful detection and treatment of a depressive illness and prevention of its effects on parenting and the health of children is a formidable challenge to modern health care systems. This study offers seven solid recommendations designed to increase awareness about and remove barriers to care for both the depressed adult and prevention of effects in the child. The report will be of particular interest to federal health officers, mental and behavioral health providers in diverse parts of health care delivery systems, health policy staff, state legislators, and the general public.




Stress Resilience


Book Description

Stress Resilience: Molecular and Behavioral Aspects presents the first reference available on the full-breadth of cutting-edge research being carried out in this field. It includes a wide range of basic molecular knowledge on the potential associations between resilience phenomenon and biochemical balance, but also focuses on the molecular and cellular mechanisms underlying stress resilience. World-renowned experts provide chapters that cover everything from the neural circuits of resilience, the effects of early-life adversity, and the transgenerational inheritance of resilience. This unique and timely book will be a go-to resource for neuroscientists and biological psychiatrists who want to improve their understanding of the consequences of stress and on how some people are able to avoid it.




Recognition and Alleviation of Distress in Laboratory Animals


Book Description

Scientific advances in our understanding of animal physiology and behavior often require theories to be revised and standards of practice to be updated to improve laboratory animal welfare. This new book from the Institute for Laboratory Animal Research (ILAR) at the National Research Council, Recognition and Alleviation of Distress in Laboratory Animals, focuses on the stress and distress which is experienced by animals when used in laboratory research. This book aims to educate laboratory animal veterinarians; students, researchers, and investigators; animal care staff, as well as animal welfare officers on the current scientific and ethical issues associated with stress and distress in laboratory animals. It evaluates pertinent scientific literature to generate practical and pragmatic guidelines. Recognition and Alleviation of Distress in Laboratory Animals focuses specifically on the scientific understanding of the causes and the functions of stress and distress, the transformation of stress to distress, and the identification of principles for the recognition and alleviation of distress. This book discusses the role of humane endpoints in situations of distress and principles for the minimization of distress in laboratory animals. It also identifies areas in which further scientific investigation is needed to improve laboratory animal welfare in order to adhere to scientific and ethical principles that promote humane care and practice.







Modeling Neuropsychiatric Disorders in Laboratory Animals


Book Description

Modeling Neuropsychiatric Disorders in Laboratory Animals serves as a guide for students and basic investigators in the fields of behavioral sciences, psychology, neuroscience, psychiatry, and other professionals interested in the use of animal models in preclinical research related to human neuropsychiatric disorders. The text focuses on the rationale and theory of using animal behavior, both pathological and normal, as a tool for understanding the neural underpinnings of neuropsychiatric disorders. Chapters contain discussions on both classical and modern views on the validation of animal models for neuropsychiatric disorders, also discussing the utility of endophenotypes in modeling neuropsychiatric disease. Subsequent chapters deal with four specific classes of disorders, including anxiety disorders, depressive disorders, obsessive-compulsive and related disorders. Final sections discuss the future for the development, validation, and use of animal models in basic and preclinical research. - Focuses on the rationale and theory of using animal behavior, both pathological and normal, as a tool for understanding the neural underpinnings of neuropsychiatric disorders - Serves as a guide for students and basic investigators in the fields of behavioral sciences, psychology, neuroscience, psychiatry, and other professionals - Discusses specific classes of disorders, including anxiety disorders, depressive disorders, obsessive-compulsive and related disorders




Perspectives on Anxiety, Panic, and Fear


Book Description

Modern conceptualization of the multidimensional nature of anxiety, panic, and fear are examined from a variety of perspectives, including theories of emotion and cognition, neuropsychology, and conditioning.øCarroll E. Izard and Eric A. Youngstrom open with a review of Differential Emotions Theory. In the second chapter, Jeffrey A. Gray and Neil McNaughton summarize and update Gray's neuropsychological theory of anxiety. Susan Mineka and Richard Zinbarg consider what modern conditioning theory contributes to the understanding of emotion, and Richard J. McNally offers an overview of the application of experimental cognitive paradigms to fear, panic, and anxiety.øThe volume concludes with a new version of David H. Barlow's theory of emotional disorders. Barlow, Bruce F. Chorpita, and Julia Turovsky draw from work on emotion, neurophysiology, attributions, learning, ethology, attention, and child development to describe how the inappropriate activation of fear (e.g., a panic attack) can trigger events that may eventually become a clinical anxiety disorder.øPerspectives on Anxiety, Panic, and Fear confirms that anxiety, panic, and fear are complex phenomena requiring a multidimensional approach that ranges from neuroanatomy to conditioning.




Stress and Health
