Shared psychotic disorder characterized by Capgras syndrome is an extremely rare condition. To our knowledge, there are only a few published papers on this condition. This paper presents a case of shared Capgras syndrome in two sisters. The inducer was a younger sister with schizophrenia, who passed on her Capgras delusion to her older sister after the death of their father. After committing a violent offense caused by Capgras delusion, a court ordered the sisters' involuntary admission to a psychiatric hospital. After being separated and receiving antipsychotic treatment, the sisters showed substantial improvement. However, shortly after hospital discharge, they stopped taking their medication and disappeared. After 15 years, their mother died and shortly afterwards, the sisters were re-admitted for forensic psychiatric evaluation after another violent crime caused by Capgras delusion. Timely recognition, adequate treatment and maintaining a therapeutic alliance could contribute to a better clinical course and outcome of this disorder, and reduce the risk of violent behavior.
以卡普格拉综合征为特征的共享精神病性障碍是一种极为罕见的病症。据我们所知,仅有少数关于该病的已发表论文。本文报告了一对姐妹中发生的共享卡普格拉综合征病例。诱发因素是一位患有精神分裂症的妹妹,在父亲去世后,她将卡普格拉妄想传给了姐姐。在因卡普格拉妄想而实施暴力犯罪后,法院下令将姐妹俩强制送医。在接受分离和抗精神病治疗后,姐妹俩的病情有了显著改善。然而,在出院后不久,她们停止服药并失踪了。15 年后,她们的母亲去世,不久之后,由于卡普格拉妄想再次导致暴力犯罪,姐妹俩被重新送医进行法医精神病学评估。及时识别、充分治疗和维持治疗联盟有助于改善该病的临床病程和结局,并降低暴力行为的风险。
