The current considerations about completed suicides and suicide attempts in different cultures call the attention of professionals to this serious public health problem. Integrative approaches have shown that the confluence of multiple biological and social factors modulate various psychopathologies and dysfunctional behaviors, such as suicidal behavior. Considering the level of intermediate analysis, personality traits and cognitive functioning are also of great importance for understanding the suicide phenomenon. About cognitive factors, we can group them into cognitive schemas of reality interpretation and underlying cognitive processes. On the other hand, different types of primary cognitive alterations are related to suicidal behavior, especially those resulting from changes in frontostriatal circuits. Among such cognitive mechanisms can be highlighted the attentional bias for environmental cues related to suicide, impulsive behavior, verbal fluency deficits, non-adaptive decision-making, and reduced planning skills. Attentional bias consists in the effect of thoughts and emotions, frequently not conscious, about the perception of environmental stimuli. Suicidal ideation and hopelessness can make the patient unable to find alternative solutions to their problems other than suicide, biasing their attention to environmental cues related to such behavior. Recent research efforts are directed to assess the possible use of attention bias as a therapeutic target in patients presenting suicide behavior. The relationship between impulsivity and suicide has been largely investigated over the last decades, and there is still controversy about the theme. Although there is strong evidence linking impulsivity to suicide attempts. Effective interventions address to reduce impulsivity in clinical populations at higher risk for suicide could help in the prevention. Deficits in problem-solving ability also seem to be distorted in patients who attempt suicide. Understanding cognitive changes in patients who attempt suicide open an important perspective in the approach of patients with mental disorders. Identifying cognitive deficits in these patients, along with personality traits, depressive symptoms, and suicidal cognitive schemas may indicate to the psychiatrist the need for emergency care. Behavioral and cognitive interventions have been associated with reductions in suicide ideation, as well as suicide attempts in different populations.
当前对不同文化中自杀身亡和自杀未遂情况的思考,引起了专业人士对这一严重公共卫生问题的关注。综合方法表明,多种生物和社会因素的交汇调节着各种精神病理学和功能失调行为,如自杀行为。从中级分析层面来看,人格特质和认知功能对于理解自杀现象也非常重要。关于认知因素,我们可以将它们分为现实解释的认知模式和潜在的认知过程。另一方面,不同类型的原发性认知改变与自杀行为有关,尤其是那些由额纹状体回路变化引起的改变。在这些认知机制中,可以突出与自杀相关的环境线索的注意偏向、冲动行为、言语流畅性缺陷、非适应性决策和计划能力下降。注意偏向在于思想和情感(通常是无意识的)对环境刺激感知的影响。自杀念头和绝望感可能使患者除了自杀之外找不到解决问题的其他替代办法,从而使他们的注意力偏向与这种行为相关的环境线索。最近的研究致力于评估注意偏向作为自杀行为患者治疗靶点的可能性。在过去几十年里,冲动性与自杀之间的关系得到了大量研究,关于这个主题仍然存在争议。尽管有强有力的证据将冲动性与自杀未遂联系起来。针对降低自杀风险较高的临床人群的冲动性的有效干预措施可能有助于预防自杀。自杀未遂患者的解决问题能力缺陷似乎也受到了扭曲。了解自杀未遂患者的认知变化为精神障碍患者的治疗开辟了一个重要视角。识别这些患者的认知缺陷,连同人格特质、抑郁症状和自杀认知模式,可能会向精神科医生表明需要进行紧急护理。行为和认知干预与不同人群中自杀念头以及自杀未遂情况的减少有关。
