Shared Psychotic Disorder (Folie À Deux): A Rare Case with Dissociative Trance Disorder That Can Be Induced

Abstract

BACKGROUND:Shared psychotic disorder was first introduced in the 19th century in France with the name Folie à deux. Since then, the concept of Folie à deux has been developed and produces several subtypes in France. In DSM, this disorder is called Shared Psychotic Disorder, and in ICD-10, it is called Induced Delusional Disorder. However, some of the classic subtypes of Folie à deux are not included in the above categories.CASE REPORT:We found a case of shared psychotic disorder between a 38-year-old male inducer, a Batak tribe with two female recipients, 34 and 36 years from the Batak tribe. They were found to share the same delusions and hallucinations, and inducers could make recipients into trance conditions. These three individuals did not get along with the surrounding community and often carried out activities and perform rituals together.CONCLUSION:Overall, our case has some unique features of folie à deux. In this case, there is a trance condition that can be induced that have not been reported in the literature or case reports related to Folie à deux.

A Case Report of Family Relations in Shared Psychotic Disorder

“…Meanwhile, SPD is a rare disorder characterized by the sharing of certain delusions between two or more individuals in a close relationship. The inducer (primary) has a psychotic disorder with delusions of influencing other individuals based on beliefs [6,11]. Therefore, there is a plan to undertake family therapy and administer antipsychotics.…”

“…Other special forms have been reported, such as folie simultanée, in which two individuals develop psychotic simultaneously and share the same delusions. SPD can be classified into 4 kinds, including a-folie imposée (lasègue and falret), b-folie simultanée (régis), c-folie communiqué (marandon de montyel), and d-folie induite, according to a study published in 1942 by Gralnick (lehman) [2,4,6].…”

Case Report: Trance in Mental Retardation

“…In establishing the diagnosis of a disorder, it is necessary to pay attention whether the diagnosis meets the criteria or not, in this case, the ICD-10 diagnostic criteria are used. Tables 1 and 2 will briefly describe the diagnosis of MR and DTD [1], [2], [7], [8]. Based on the case report above, after a complete psychiatric medical history examination, clinical interview, IQ test, psychological test, and mental status examination were carried out and referring to the diagnostic criteria in Tables 1 and 2, it was found that the patient met the diagnostic criteria for mild MR with DTD.…”

“…According to the DSM, to assess its" utility "(a collection of parameters and axes are given for further analysis"), the disorder needs further study. Despite these distinctions, both definitions use the same criterion and view DTD as a transient altered state of consciousness (ASC), whose characteristics are influenced by the culture of a person [6], [7], [8].…”

A Case Study of Possession and Trance Disorder in Salai Jin Ritual: Etiology, Diagnostics, and Therapeutics

“…It's also crucial to remember that the symptoms must be capable of significantly impairing or causing distress in daily activities such as personal, family, social, educational, and occupational activities. However, the adoption of the "possessed" role by an individual can be a primary (reaction or chance to express conflicting impulses in a culturally acceptable way) and secondary (attracting the attention of others and evoking respect or admiration) source of distinct advantages [5][6][7]. Unless the trance episodes reoccur, one trance episode is likely to last at least several days per the ICD, and a trance episode is expected to result in full or partial amnesia.…”
