BACKGROUND: Folie à deux is a very rare psychiatric syndrome in which a psychotic symptom is transmitted from one individual to another. We present a case of folie à deux occurring during childhood, which is not an usual presentation of this syndrome. In this case, the disorder is correlated with child abuse and neglect, which possibly had a role in the development of the symptoms in our case. CASE PRESENTATION: We present a case of folie à deux between an "induced" 9-year-old black Brazilian boy and the "inducer", his grandmother...

REVIEW
Oliver H Turnbull, Christian E Salas
Confabulations offer unique opportunities for establishing the neurobiological basis of delusional thinking. As regards causal factors, a review of the confabulation literature suggests that neither amnesia nor executive impairment can be the sole (or perhaps even the primary) cause of all delusional beliefs - though they may act in concert with other factors. A key perspective in the modern literature is that many delusions have an emotionally positive or 'wishful' element, that may serve to modulate or manage emotional experience...

BACKGROUND AND OBJECTIVES: Delusions of reference are thought to reflect abnormally heightened attributions of salience to mundane events or stimuli that lead to convictions that they are personally significant or directed at the observer. Recent findings highlight abnormal recruitment of brain regions associated with self-referential processes among patients with referential delusions. Given the inherent overlap of emotion, incentive salience, and self-relevance, as well as with aberrant thought processes in psychosis, this study investigated the implicit relations between participants' perception of the emotional valence of stimuli on neural correlates of self-referent judgments among schizophrenia-spectrum patients with referential delusions...

Strong familial aggregation of schizophrenia has been reported but there is uncertainty concerning the degree of genetic contribution to the phenotypic variance of the disease. This study aimed to examine the familial aggregation and heritability of schizophrenia, and the relative risks (RRs) of other psychiatric diseases, in relatives of people with schizophrenia using the Taiwan National Health Insurance Database. The study population included individuals with affected first-degree or second-degree relatives identified from all beneficiaries (n = 23 422 955) registered in 2013...

The Capgras syndrome (CS) is a rare psychiatric disorder. CS is classified as a delusional misidentification syndrome. Initially, CS was described in paranoid schizophrenia and schizoaffective disorders. CS has also been reported in neurodegenerative diseases such as Alzheimer's disease and Lewy body dementia. To date, there are very few descriptions of the occurrence of CS in idiopathic Parkinson's disease (PD), with or without dementia. Considering the recent observation of two new cases in PD patients, a systematic overview of the literature published between 1976 and 2016 reporting CS in PD was conducted...

The author analyzes the features of the syndrome of «delusional fantasies» (delusion-like fantasies) in the concept of K. Birnbaum. According to this concept, psychopathic constitutions, due to the presence in the structure of dissociation, are the basis for the development of delusions per se. «Dreamer» and «vershroben» types are predisposed to the syndrome of «delusional fantasies». It is emphasized that initially the syndrome of «delusional fantasies» was described as a peculiar phasic episode of delusions in psychopaths, aged between 20-30 years...

PURPOSE: To explore the association between histories of common mental disorders, delusional-like experiences, and recent physical activity using a large nationally representative population-based sample from Australia. We predicted that a past history of a common mental disorder or delusional-like experiences would be associated with insufficient physical activity. METHODS: The study was based on the Australian National Survey of Mental Health and Wellbeing 2007 (n = 8841)...

BACKGROUND: The categories of functional psychoses build on views of influential professionals. There have long been four main categories - affective, schizophrenic, schizoaffective/cycloid/reactive/polymorphic, and delusional/paranoid psychoses. The last three are included in "psychotic disorders". However, this dichotomy and the distinctions between categories may have been over-estimated and contributed to lack of progress.

PURPOSE: Women suffering from schizophrenia-spectrum disorders may differ from men in clinical course and outcome. Still, those differences can only be portrayed accurately by means of studies that derive information from multiple sources. One such study was performed in a well-defined area supported by a Mental Health Clinical Management Unit in Malaga, Spain. METHODS: Data from 1640 patients (1048 men and 592 women) that were in contact with services during 2008 were examined for the purpose of the present analysis...

BACKGROUND: The role of cognitive biases in delusion and delusion-like experiences has been widely investigated in recent years. However, little is known about individual differences, which may influence association between cognitive biases and formation of delusional beliefs. The aim of this study was to examine the moderating effect of self-reported attentional control on the relationship between attention to threat bias (ATB) and delusion-like experiences (DLEs) in healthy adults. METHODS: Participants (n=138) completed the Davos Assessment of the Cognitive Biases Scale (DACOBS), the Attentional Control Scale (ACS) and the Peters et al...

Importance: Neurocognition is a central characteristic of schizophrenia and other psychotic disorders. Identifying the pattern and severity of neurocognitive functioning during the "near-psychotic," clinical high-risk (CHR) state of psychosis is necessary to develop accurate risk factors for psychosis and more effective and potentially preventive treatments. Objectives: To identify core neurocognitive dysfunctions associated with the CHR phase, measure the ability of neurocognitive tests to predict transition to psychosis, and determine if neurocognitive deficits are robust or explained by potential confounders...

INTRODUCTION: Ingestion of foreign bodies has been previously reported in some patients with schizophrenia. This behavior may be a manifestation of delusional beliefs or a response to command hallucinations and can lead to severe complications. CASE PRESENTATION: This paper reports a patient with schizophrenia who, as a manifestation of his illness, ingested a metallic skewer to kill ademon inside his abdomen that he believed was controlling him. As a result, he developed an acute intestinal perforation and underwent surgery...

Morgellons disease (MD) is a dermopathy characterized by multicolored filaments that lie under, are embedded in, or project from skin. Although MD was initially considered to be a delusional disorder, recent studies have demonstrated that the dermopathy is associated with tickborne infection, that the filaments are composed of keratin and collagen, and that they result from proliferation of keratinocytes and fibroblasts in epithelial tissue. Culture, histopathological and molecular evidence of spirochetal infection associated with MD has been presented in several published studies using a variety of techniques...

Introduction: Post-operative delirium remains a significant problem, particularly in the older surgical patient. Previous evidence suggests that the provision of supplementary visual feedback about ones environment via the use of a mirror may positively impact on mental status and attention (core delirium diagnostic domains). We aimed to explore whether use of an evidence-based mirrors intervention could be effective in reducing delirium and improving post-operative outcomes such as factual memory encoding of the Intensive Care Unit (ICU) environment in older cardiac surgical patients...

INTRODUCTION: An 'overconfidence in errors' bias has been consistently observed in people with schizophrenia relative to healthy controls, however, the bias is seldom found to be associated with delusional ideation. Using a more precise confidence-accuracy calibration measure of overconfidence, the present study aimed to explore whether the overconfidence bias is greater in people with higher delusional ideation. METHODS: A sample of 25 participants with schizophrenia and 50 non-clinical controls (25 high- and 25 low-delusion-prone) completed 30 difficult trivia questions (accuracy <75%); 15 'half-scale' items required participants to indicate their level of confidence for accuracy, and the remaining 'confidence-range' items asked participants to provide lower/upper bounds in which they were 80% confident the true answer lay within...
