Folie à deux is a psychiatric illness involved in homicides.
To study the mechanisms leading to homicide and determine homicide risk factors in folie à deux patients through a literature review and the study of a complex clinical case.
We included articles available on PubMed, ScienceDirect or Cairn that address the forensic implications of folie à deux. Then, we analyzed the criminal psychiatric assessments of two murderers (husband and wife) of a child in a case of folie à deux.
Seventeen articles were included. In the cases examined, homicides were committed with great violence, usually against a victim in the family circle, and were sometimes followed by suicide. The main risk factor for homicide was the combination of mystical and persecutory delusions. The homicides occurred in response to destabilization of the delusional dyads. Concerning the clinical case, we described the circumstances surrounding the killing and analyzed the four expert reports that permit us to infer the occurrence of induced psychosis, which is a form of folie à deux.
Psychiatrists must attain a better knowledge of folie à deux to allow early identification of risk situations and to improve their assessments.
感应性精神病是一种与杀人行为有关的精神疾病。
通过文献综述和一个复杂临床病例的研究，探讨感应性精神病患者导致杀人行为的机制并确定杀人风险因素。
我们纳入了在PubMed、ScienceDirect或Cairn上可获取的涉及感应性精神病法医意义的文章。然后，我们分析了一例感应性精神病中两名杀害儿童凶手（夫妻）的刑事精神病学评估。
纳入了17篇文章。在所研究的案例中，杀人行为具有极大暴力性，通常针对家庭成员，有时随后会自杀。杀人的主要风险因素是神秘妄想和被害妄想的结合。杀人行为是对妄想二元组不稳定的反应。关于该临床病例，我们描述了杀人事件的相关情况，并分析了四份专家报告，这些报告使我们能够推断诱导性精神病（感应性精神病的一种形式）的发生。
精神科医生必须更好地了解感应性精神病，以便早期识别风险情况并改进评估。
