Despite its popularity in the lay media, alleged possession of children by demons has received scant attention in the scientific literature. Five cases are presented. This phenomenon probably represents a variant of folie à deux. A religious consultant may advantageously be included as a member of the treatment team.
We described a case of "folie à deux" in a wife husband couple. We observed the syndrome gradually developing while following the husband in therapy for others reasons. Psychodynamic hypothesis for the occurrence and function of the disorder in this couple are discussed.

We present a case of shared psychotic disorder involving three sisters who were successful in establishing an insanity defense on numerous felony charges in the South Carolina criminal court system. Two of the authors of this article were court-appointed examiners in this case. We then present a history of shared psychotic disorder, an overview of the use of this diagnosis in the defense of insanity, and a discussion of the disposition of individuals with "temporary insanity." Finally, we compare shared psychotic disorder, culturally based belief systems, and religious cults, with a focus on their common and contrasting characteristics.

Some of the factors that influence an analyst to choose one construction rather than another are explored. Such choices may be based on the analyst's insights and development, or his biases, past training and personal pathology; or the patient's attempts to influence the analyst in a particular direction. Construction may overemphasize the part played by the patient's innate propensities or his environment. Freud's interpretation of the Oedipus myth is re-examined in the light of these thoughts. Reconstruction is considered to be of therapeutic value only through the analysis of the repetition compulsion in the transference. The clinical examples include consideration of the repetition of an early folie à deux phenomenon manifest in the transference. The nature of the internal objects that 'go with' the patient in exploration and distortion of truths is examined. New developments in analysis need to be integrated with creative constructions of the past, forming the foundation of new constructions. The view is held that in times of crisis patients revert to past systems; recognition of this factor implies that the work of reconstruction will be an on-going process after the analysis is terminated, and forms part of the patient's equipment for future self analysis.
This article reports the noteworthy case of a couple who developed three clearly separate delusions after marriage. An elaborated delusion of descent was shared by the two people, while two further delusions remained private convictions. Probable biographical connections of the shared delusions and diagnostic problems are discussed, especially the monocausal etiologic hypotheses behind the respective categories for shared psychotic disorders of ICD and DSM.
A review of folie à deux or induced psychotic disorder (DSM-III-R) is provided. The author believes it to be a more frequent phenomenon than usually thought, especially when hospitalized patients are evaluated with their families. An argument is made for viewing it as a description of a relationship and possible influence between individuals who may have very different disease processes. This includes, in the secondary partner, a continuum from being very "impressionable" to having an autonomous and independent delusional disorder. A case report and suggestions for treatment are given.
There are very few publications about the induction of emotional disturbances in Munchausen by proxy syndrome, although we see these children in our clinical work. While the pathology of the inducing mothers has been described quite well, the equally important question of pathological reactions of the child, which is a major factor at least in adolescents, has not yet been discussed. We present an unusual case of induced borderline psychosis and discuss the above mentioned aspect in relation to several psychopathological concepts, particularly Erikson's identity diffusion and folie à deux. We conclude that the concept of a simple induction of the disturbance in adolescents, which has been used so far, is insufficient. According to the authors the importance of the reactions discussed in this paper reaches far beyond Munchausen by proxy syndrome. The same reactions can for example be seen also in cases of sexual abuse. A bigger sample of patients needs to be investigated to confirm our considerations.
This paper presents a review of the current literature on cotherapy with special reference to therapeutic outcome. The review covers the fields of sex therapy, group therapy, and family and marital therapy. It considers both patient variables and cotherapist variables. There are few "research" studies of cotherapy. Most data derive from case illustrations, which, however well detailed, are anecdotal in nature. The most widely addressed effect of cotherapy upon patients is presented in terms of treatment process and not treatment outcome.
A case report of shared delusional disorder, with a primary diagnosis of delusional disorder, is described in identical twins of proven zygosity. A review of literature shows that the primary diagnosis in identical twin pairs, suffering from folie à deux, is delusional disorder. This is in contrast to the reported excess of schizophrenia, as a primary diagnosis, in non-twin cases of folie à deux. Moreover, schizophrenia is poorly related to delusional disorders on the basis of demographic and familial studies. In the light of this paradox, nosological status of this disorder and the sociogenic and genetic factors are critically discussed.

Delusional parasitosis is the false belief that one's body is infested with one or many different living organisms. Historically, it has been treated with conventional antipsychotics with only moderate success. The conventional antipsychotic most commonly used has been pimozide. We report a series of five cases of patients with delusional parasitosis. Our patients' demographic characteristics were similar to those in previously published case reports, but instead of being treated with older antipsychotics, they were all treated with atypical antipsychotic agents with favorable results. We will discuss the rationale for this treatment choice, and will review the role of serotonin/dopamine antagonists in the treatment of delusional parasitosis. We will also comment on the possible role of serotonergic antidepressants in the treatment of these patients.
Over the last century there have been reports in the psychiatric journals of an unusual disorder, folie à famille, yet the syndrome has been neglected by family theorists. In this paper the literature on delusions shared by families is examined from the perspective of a family therapist. The role the disorder plays in defining the continuum of functional/dysfunctional shared familial beliefs is described, and a case example demonstrating that folie à famille may be underreported is presented.
Folie à deux is a rare, interesting disorder involving delusional beliefs shared by two persons. We report three cases of elderly couples referred to our service during an 18-month period with this disorder, and discuss the salient clinical features and the possible risk factors for folie à deux in the elderly.
Shared (Induced) Delusional Disorder commonly occurs in close relationships and involves a varying number of participants who may be nonconsanguineous. The disorder has been associated with forensic and fatal consequences. Its occurrence in three nonrelated, incarcerated individuals is described in this article. This case of folie à trois has forensic implications and raises several questions of ethics that relate to autonomy, confidentiality, safety, and risk estimation. The presentation, management, and outcome of the patients suggest that a high index of suspicion is needed to detect cases in similar settings. The report concludes that the rarity of the disorder in a forensic mental health population may be the result of underdetection, given that conditions are conducive to the development of the disorder. Telltale signs of its manifestation are hypothesized as being responsible for some events in incarcerated populations. Physical separation and antipsychotic medications remain the mainstay of treatment.
Induced psychotic disorder is a very rare clinical picture. We describe here one occurrence which included four members of the same family. A brief review of the literature is made and several etiological factors are discussed.
