Editorial: A global perspective on suicidal behaviour and ideation: demographics, biomarkers and treatment

Suicide is an alarming public health issue that transcends geographical, cultural, and socioeconomic boundaries (1). The complexity of its causes and manifestations necessitates the continuous exploration and understanding of its various aspects. In recent decades, suicide has become a leading cause of death worldwide, with devastating social, psychological, and economic consequences (2). Despite the increasing recognition of this public health crisis, there is a persistent need for a comprehensive understanding of suicidal behavior and ideation in order to develop more effective prevention and intervention strategies. In this editorial, we will explore the complex and multifaceted nature of suicide, examining its demographics, biomarkers, and treatment from a global perspective. By shedding light on this challenging subject, we aim to contribute to the ongoing conversation surrounding mental health and stimulate further research and collaboration across disciplines and borders. The focus of this Research Topic is understanding suicidal behavior and ideation from a global perspective. In this special issue, we have gathered eight articles that contribute to this ongoing dialogue, providing valuable insights into suicide risk factors, assessment, and prevention strategies across diverse populations and contexts. The collection of papers includes brief research reports, original research, perspectives, reviews, and retrospective case series. The contributions come from a variety of disciplines and are based on diverse research populations in Bulgaria, Australia, Spain, Hungary, and China.
