Globally, hundreds of thousands of people die by suicide every year. Suicides are usually associated with psychiatric illness. However, considerable evidence suggests that a significant number of individuals who die by suicide do not have diagnosable psychiatric disorders. The goal of this article is to attract attention to an overlooked issue of suicide in persons with no psychiatric disorders and to discuss some aspects of this issue. Research on identification and prevention of suicidal behavior in people with no psychiatric disorders is very limited. The available data indicates that suicides in individuals without psychiatric disorders are related to life stressors, lack of social support, and certain personality traits such as impulsivity. Suicide risk may be increased in military veterans with no psychiatric disorders. Many physical disorders, especially conditions associated with pain increase suicide risk in individuals with no diagnosable psychiatric disorders. Developmental, genetic, and physical factors may play a role in the psychobiology of suicide in people with no psychiatric conditions. Promoting resilience may reduce suicide risk in the general population. Clinicians who work with medical or surgical patients need to have sufficient training in suicide prevention. Possibly, shifting some suicide prevention resources from individuals who are regarded as high-risk suicide patients to the general population may reduce suicide rates. Public education and better awareness about suicide may reduce suicide deaths among people with no psychiatric disorders.

没有精神疾病的人会自杀——是什么让你变得脆弱？

在全球范围内，每年有数十万人死于自杀。自杀通常与精神疾病有关。然而，大量证据表明，大量自杀者并未患有可诊断的精神疾病。本文的目的是引起人们对无精神疾病者自杀问题的关注，并讨论该问题的某些方面。关于识别和预防无精神疾病人群自杀行为的研究非常有限。现有数据表明，没有精神疾病的个体的自杀与生活压力、缺乏社会支持以及冲动等某些人格特征有关。没有精神疾病的退伍军人的自杀风险可能会增加。许多身体疾病，尤其是与疼痛相关的疾病，会增加没有可诊断精神疾病的个体的自杀风险。发育、遗传和身体因素可能在没有精神疾病的人自杀的心理生物学中发挥作用。提高复原力可以降低普通人群的自杀风险。与内科或外科患者一起工作的临床医生需要接受足够的自杀预防培训。将一些自杀预防资源从被视为高风险自杀患者的个人转移到普通人群可能会降低自杀率。公众教育和提高对自杀的认识可能会减少没有精神疾病的人的自杀死亡人数。
