Suicide is undoubtedly a worldwide major challenge for the public health. It is estimated that more than 150,000 persons in Europe die as a result of suicide every year and in several European countries suicide represents the principal cause of death among young people aged 14–25 years. It is true that suicide is a complex (and yet not fully understood) phenomenon and may be determined by the interaction between various factors, such as neurobiology, personal and familiar history, stressful events, sociocultural environment, etc. The suicide is always a plague for the population at risk and one of the most disgraceful events for a human being. Moreover, it implies a lot of pain often shared by the relatives and persons who are close to suicide subjects. Furthermore, it has been widely demonstrated that the loss of a subject due to suicide may be one of the most distressing events that may occur in mental health professionals resulting in several negative consequences, such as burnout, development of psychiatric symptoms and lower quality of life and work productivity. All considered, it is clear that the suicide prevention is a worldwide priority and every effort should be made in order to improve the early recognition of imminent suicide, manage suicidal subjects, and strengthen suicide prevention strategies. In our opinion, the first step of prevention is the improvement of knowledge in the field: this was the aim of this present special issue on Frontiers in Psychiatry. In this special issue, several papers have contributed to the suicide knowledge from several viewpoints and we hope that this will contribute to improve and disseminate knowledge on this topic.

Suicide is a highly complex and multifaceted phenomenon, with many contributing and facilitating factors and variables. However, given its being one of the most severe human behaviors, an obvious focus would be to identify the underlying psychological mechanisms and processes that may lead to suicidal ideation and behavior. This eBook is dedicated to studies exploring various approaches to the psychology of suicidal behavior as well as of non-suicidal self-injury (NSSI). The purpose of this eBook is to shed light on in-depth examinations of the current knowledge and empirical data regarding models, theories, and specific dimensions and variables that may help us increase the psychological understanding of suicidal phenomena. The specific goal is to identify particular psychological characteristics that may be used to develop prevention and intervention methods and programs. We believe that this eBook can contribute to the understanding of this behavior and help to develop specific tools, therapeutic guidelines, and programs that may help reduce the number of suicides occurring annually. This eBook is dedicated to our dearest friend, Dafni Assaf, who was one of the greatest leaders of the suicide prevention program in Israel.

A practical and easy-to-use guide for healthcare professionals on the prevention, assessment and treatment of people at risk of suicide.

The Suicidal Crisis has everything clinicians need to evaluate the risk of imminent suicide. What sets it apart is its clinical focus on those at the highest risk--the book includes individual case studies of acutely suicidal individuals, detailed instructions on how to conduct risk assessments, test cases with answer keys, and empirically validated Suicidal Crisis risk assessment scales.

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.
