A Study of the Neurobiological Mechanisms of Non-suicidal Self-injurious Behaviour

Non-suicidal self-injury (NSSI) often occurs in adolescence and early adulthood, accompanied by an increase in the incidence and development of related diseases, making it a significant risk factor for suicide. NSSI behavior among adolescents has become a serious public health issue, threatening their physical and mental development. This article explores the identification methods, biological causes, and emotional causes of NSSI behavior and provides current applicable treatment interventions. By elaborating on the harm of NSSI behavior to adolescents, identification methods, and intervention strategies are proposed to provide a theoretical basis for monitoring and protecting adolescent health in order to improve NSSI behavior among adolescents.
