Abstract

Background

Folie à deux, also known as shared psychotic disorder, is a rare psychiatric syndrome in which a psychotic symptom is transmitted from one individual to another who is usually in close proximity. We report a case of folie à deux in adult monozygotic female twins who presented to the emergency department with disturbed behavior amid the Coronavirus disease 2019 (COVID-19) lock down.

Case report

We present the case of 23-year-old monozygotic female twins, with no past medical or psychiatric history, who presented with a two-week history of irritability, sleeplessness, and hyperreligiosity. They were found to be sharing a similar delusional belief with a religious theme. Routine investigations and brain imaging were unrevealing. The primary case (Twin A) was diagnosed with brief psychotic disorder and started on an oral antipsychotic. The secondary case (Twin B) showed gradual resolution of symptoms after separation from twin A.

Conclusion

This case highlights the complex interplay between genetic and environmental factors in the etiology of delusional symptoms in monozygotic twins.

23岁的同卵双胞胎在COVID-19大流行中共享错觉

folie deux，也被称为共享性精神障碍，是一种罕见的精神综合征，其中一种精神症状通常从一个人传播到另一个人。我们报告了一例成年同卵女双胞胎的folie deux，她在2019冠状病毒病(COVID-19)封锁期间因行为异常而向急诊室就诊。病例报告:我们报告一例23岁的同卵女性双胞胎，无既往病史或精神病史，表现为两周的易怒、失眠和过度宗教信仰史。他们被发现有着相似的宗教主题妄想信仰。常规检查和脑成像没有发现。最初的病例(双胞胎A)被诊断为短暂的精神障碍，并开始口服抗精神病药物。继发性病例(双胞胎B)在与双胞胎a分离后症状逐渐消退。结论本病例突出了基因和环境因素在同卵双胞胎妄想症状病因学中的复杂相互作用。
