Folie à deux is a rare condition in which a single person (often with a psychiatric disorder) develops a delusion that is shared by another person. Folie à troix is when a delusion is shared by three people. This case report documents the unusual case of an individual who shared delusions with two different people simultaneously. This report inspires questions about this person, her delusions, and what made them so believable to others. It is known that the development of shared delusions most commonly occurs in relative isolation and disproportionately affects individuals with preexisting psychiatric comorbidities. Because of these risk factors, delusions in a psychiatric unit may be even more "contagious" than in the general population. To our knowledge, this case report is the first to document a newly developed delusion shared between two unrelated patients in a single psychiatric unit. While physical separation of patients is the best practice in such cases, a risk-benefit analysis is needed prior to this intervention given the social barriers that may limit such an approach. Further research is needed to diagnose, manage, and optimize treatment for shared delusions in settings such as inpatient psychiatric facilities.
感应性精神病是一种罕见的病症，其中一个人（通常患有精神疾病）产生的妄想会被另一个人共享。三人感应性精神病是指一种妄想被三个人共享的情况。本病例报告记录了一个人同时与两个不同的人共享妄想的不寻常案例。这份报告引发了关于这个人、她的妄想以及是什么让这些妄想对其他人如此可信的问题。已知共享妄想的形成最常发生在相对孤立的环境中，并且对已有精神疾病合并症的个体影响不成比例。由于这些风险因素，精神科病房中的妄想可能比普通人群中更具“传染性”。据我们所知，本病例报告是首次记录在单个精神科病房中两名无亲属关系的患者之间新形成的共享妄想。虽然在这种情况下对患者进行物理隔离是最佳做法，但鉴于可能限制这种方法的社会障碍，在采取这种干预措施之前需要进行风险效益分析。需要进一步研究以诊断、管理和优化住院精神科设施等环境中共享妄想的治疗。
