Stress and Epigenetics in Suicidediscusses the central role of epigenetic modifications in suicidal behavior. As early-life stress and an individual's ability to cope with such stressors, combined with psychological factors, social factors, and existential and cognitive factors can predispose young people to suicidal behavior and put them at added risk of suicidal behavior later in life, this book provides readers with an overview of the neurobiology of stress, an introduction to the epigenetic changes induced by stress, and an understanding of how vulnerability and resilience to stress are built. It integrates these mechanisms into a biobehavioral model of suicide based on epigenetic marks, gene-environment interactions, and other stressors. More importantly, it provides future direction for research and discusses potential interventions. This book is an ideal and trusted resource for researchers and clinicians who are interested in learning how the environment can affect behavior through genetics, and for those seeking the development of new methods for suicide prevention. Explores the neurobiology of stress and stress-related epigenetics, including discussion of the role of stress-induced epigenetic changes in behavioral, emotional, and cognitive mechanisms and whether these epigenetic marks are transgenerational Provides compelling biobehavioral models of suicide based on genetics, epigenetics, and behavioral adjustment Integrates social, psychological, and existential influences, giving readers a better understanding of the interdisciplinary nature of suicide risk factors Presents future directions for suicide-prevention strategies that incorporate recent research on genomics and stress resilience

Epigenetics of Stress and Stress Disorders, Volume 31 in the Translational Epigenetics series, examines the epigenetic mechanisms involved in modifying DNA or gene expression following prolonged stress and/or trauma. Sections introduce both genetic and psychiatric foundations, including modes of epigenetic modification and gene expression that result from stress, as well as the medical knowledge required to understand stress related disorders and resilience. From here, chapters discuss epigenetic research techniques applied in recent studies, including epigenome-wide association studies (EWAS) of PTSD and resilience, the possible effects of prolonged stress on telomere shortening, and the long-term physical effects of PSTD. The book concludes by examining the possible effects of transgenerational stress-induced epigenetic alterations on the resilience of future offspring, the potential for epigenetic therapeutics, and public health implications. Examines the epigenetics of stress, trauma and related stress disorders Includes methods (e.g. EWAS), protocols and directions for further studies Connects new research to clinical practice and highlights implications for patient care, drug discovery and public health

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.

"Suicide is a problem resulting from the interaction between several factors. Among these factors, early-life adversity, characterized by child sexual and physical abuse as well as parental neglect, is one of the strongest risk factors for depression and suicidal behaviors. While it is clear that child abuse increases the risk for depression and suicide, the mechanisms mediating these effects are still unknown. Recent evidences suggest that epigenetic mechanisms may be involved in mediating the effects of early-life adversity on behavior. Early-life stress in animals has been shown to alter DNA methylation in genes regulatory regions what, in turn, has been associated with changes in gene expression and behavioral modifications. Importantly, similar changes have been reported in several genes in the human brain. However, although epigenetic modifications have been found in several genes, the extent of epigenetic changes induced by early-life adversity is still unknown and their impacts on increasing suicide risk are unclear. This thesis aims at expanding our understanding of suicide by investigating one potential mechanism by which early-life adversity may increase vulnerability to mood disorders and suicide, namely epigenetic regulation of gene expression. We first expanded our characterization of DNA methylation alterations induced by early and adult-life stress in the regulatory regions of the glucocorticoid receptor gene which is one of the most consistent alterations associated with stress, depression and suicidal behaviors. We then opted for a genome-wide characterization of DNA methylation alterations found in the brains of suicide completers with and without a history of child abuse using microarray analyses focusing on gene promoters throughout the genome. Our findings revealed several DNA methylation alterations in genes with known roles on behavioral regulation and identified several new genes and networks which may be specifically altered by early-life adversity. We also characterized the functional impact of these alterations on gene expression and promoter transcriptional activity. Overall, this work identifies and characterizes the molecular mechanisms by which environment induces behavioral changes conferring vulnerability toward mood disorders and suicidal behaviors. " --

This book addresses biopsychosocial and transcultural determinants of suicide by self-immolation, populations at risk throughout the world and prevention strategies specifically designed for young women in fragile environments. Self-immolation, the act of burning oneself as a means of suicide, is rare in high-income countries, and is usually a symbolic display of political protest among men that generally receives international media coverage. In contrast, in low- and-middle-income countries it is highly prevalent, primarily affects women, and may be one of the most common suicide methods in regions of Central and South Asia and parts of Africa. Psychiatric conditions, like adjustment disorders, traumatic stress disorders, and major depression, and family dynamics that include intimate partner violence, forced marriages, the threat of honor killings, and interpersonal family conflicts in a cultural context of war-related life events, poverty, forced migration and ethnic conflicts are important contributing factors. Written by over 40 academic psychiatrists from all continents, sociologists, and historians, the book covers topics such as region-specific cultural and historical factors associated with suicide; the role of religion and belief systems; marginalization, oppression, retraumatization and suicide risk; countertransference aspects of working in burn centers; responsible reporting and the media; and suicide prevention strategies to protect those at risk.

Approximately one million people worldwide commit suicide each year, and at least ten times as many attempt suicide. A considerable number of these people are in contact with members of the healthcare sector, and encounters with suicidal individuals form a common part of the everyday work of many healthcare professionals. Suicide: An unnecessary death examines the pharmacological, psychotherapeutic, and psychosocial measures adopted by psychiatrists, GPs, and other health-care staff, and emphasizes the need for a clearer psychodynamic understanding of the self if patients are to be successfully recognized, diagnosed, and treated. Drawing on the latest research by leading international experts in the field of suicidology, this new edition provides clinicians with an accessible summary of the latest research into suicide and its prevention. The abundance of new literature can make it difficult for those whose clinical practice involves daily contact with suicidal patients to devote sufficient time to penetrating the research and, accordingly, apply new findings in their clinical practice. In light of the WHO Mental Health Action Plan 2013-2020, this new edition is a timely contribution to the field, and a vital and rapid overview, that will increase awareness of suicide prevention methods.
