BACKGROUND: Folie à deux is a clinical condition that was first described in 19th century. It is a psychotic disorder in which two closely associated individuals share a similar delusional system. OBJECTIVES: The aim of this article is to review the nosological significance of folie à deux and to explore the disorder among patients with dementia. METHODS: Medline and Google Scholar searches were conducted for relevant articles, chapters, and books published before 2017...

Eileen Maria Joyce
Organic or secondary psychosis can be seen in diverse conditions such as toxic/metabolic disorders, neurodegenerative disease, and stroke. Poststroke psychosis is a rare phenomenon, but its study has significantly contributed to the understanding of delusion formation. The evidence from case studies of patients with focal strokes shows that delusions develop following unilateral damage of the right hemisphere. The majority of patients with right hemisphere stroke do not develop delusions however, and advanced neuroimaging analysis has elucidated why this symptom develops in only a small proportion...

The Delusional Misidentification Syndromes (DMSs) are characterized by defective integration of the normally The Delusional Misidentification Syndromes (DMSs) are characterized by defective integration of the normally fused functions of perception and recognition. The classical sub-types are: the syndromes of Capgras, Fregoli,Intermetamorphosis (mentioned in 3) and Subjective doubles. These syndromes occur in a clear sensorium and shouldbe differentiated from the banal transient misidentifications occurring in confusional states and in mania and from thenon-delusional misidentifications (e...

The current debate about the diagnostic significance of delusion revolves around two positions. The neurocognitive position conceives delusion as a non-specific, though polymorphic, symptom. The psychopathological position views features of delusion such as content and structure as having meaningful connections with diagnostic entities. This study aims at contributing to this debate by examining the association between delusional themes and diagnosis in a sample of 830 adult psychotic patients. All diagnoses were made by experienced psychiatrists according to DSM-IV or ICD-10 criteria, and in 348 patients were established with the SCID-I...

Delusional infestation (DI), also known as delusional parasitosis, consists of a patient's strong belief that he or she is infested with a nonliving substance or living organism despite lack of medical evidence to support this belief. The most commonly reported sources of infestation include insects, fibrous strands, worms, and scabies. DI is predominantly seen in women and older patients. This disorder has a variable course and prognosis in patients. DI can be a primary psychiatric problem, or secondary to underlying medical conditions or other psychiatric disorders...

BACKGROUND: Little evidence is available for head-to-head comparisons of psychosocial interventions and pharmacological interventions in psychosis. We aimed to establish whether a randomised controlled trial of cognitive behavioural therapy (CBT) versus antipsychotic drugs versus a combination of both would be feasible in people with psychosis. METHODS: We did a single-site, single-blind pilot randomised controlled trial in people with psychosis who used services in National Health Service trusts across Greater Manchester, UK...

Delusional infestations are psychodermatologic disorders in which those affected have a false belief they are infested by parasites and/or "growing" inanimate objects from cutaneous surfaces. Individuals with delusional parasitosis (DP) believe parasites, bacteria, worms, mites, or other living organisms are the source of cutaneous symptoms, while those with Morgellons disease (MD) attribute their symptoms to growth of small fibers or inorganic material. In both DP and MD, self-inflicted, non-healing cutaneous lesions caused by scratching at the affected areas to alleviate symptoms are commonly observed...

This article presents a short, easy-to-use guideline for clinicians working with people with serious mental illness, particularly those with schizophrenia, schizoaffective disorder, delusional disorders, other psychotic disorders, or depression with significant impact on functioning, and may be of use for those working with individuals with bipolar disorder. This guideline is not meant to supplant the more detailed, excellent clinical practice guidelines that have been developed and published. Rather, the charts and explanation presented here are designed as a step-by-step tool that clinicians can use to ensure they are following the most appropriate course of action and providing the best psychosocial rehabilitation services possible for persons with these disorders...

Patients with delusional infestation (DI) usually reject referral to psychiatrists but will avidly seek help from dermatologists.¹, ² Psychiatrists and related healthcare staff are at risk of complaints, abuse and being stalked,³ but so are other specialties such as plastic surgeons. In a study conducted in Australasia, 20% of cosmetic and plastic surgeons reported having been harassed by patients, especially those with body dysmorphic disorder or other underlying psychopathology. No relevant data are available for dermatologists...

BACKGROUND: Recent research has identified several potentially modifiable risk factors for dementia, including mental disorders. Psychotic disorders, such as schizophrenia and delusional disorder, have also been associated with increased risk of cognitive impairment and dementia, but currently available data difficult to generalise because of bias and confounding. We designed the present study to investigate if the presence of a psychotic disorder increased the risk of incident dementia in later life...

Othello syndrome (OS) is a type of paranoid delusional jealousy, characterized by the false absolute certainty of the infidelity of a partner. Because OS has infrequently occurred in patients with Parkinson's disease (PD), the characteristics of OS in PD remain unclear. We reviewed the clinical characteristics of this syndrome in PD. We reviewed 67 patients who had PD with OS. OS was more common in men (45 patients) than in women (22 patients), and it frequently occurred in middle-aged patients. Until the onset of OS, the duration of PD (range, 2-19...

BACKGROUND: The majority of the U.S. healthcare resources are utilized by a small population characterized as high-risk, high-need persons with complex care needs (e.g., adults with multiple chronic conditions). Substance use disorders (SUDs) and mental health disorders (MHDs) are a driver of poor health and additional healthcare costs, but they are understudied among high-need patients. OBJECTIVE: We examine the prevalence and correlates of SUDs and MHDs among adults with high-risk diabetes, who are patients at the top 10% risk score for developing poor outcomes (hospital admission or death)...

BACKGROUND: Despite the major encroachment of coercive measures on the fundamental rights of affected forensic psychiatric patients, there is relatively few research done in this field. Considering the relevance of this subject for psychiatric care and the recent changes of the legal basis of coercive treatment in Germany, more studies are needed. The present study examines forensic psychiatric inpatients' perception of coercion regarding the prescribed antipsychotic medication and factors associated with the perception of coercion...

Asperger Syndrome and/or Clinical High Risk of Psychosis? A Differential Diagnostic Challenge This case-study deals with the often difficult differential diagnosis of Asperger syndrome and a clinical high risk state of psychosis, in particular as indicated by attenuated psychotic symptoms, as well as with its therapeutic implications. The presented case is a 10-year old girl, who has not been diagnosed with an autism spectrum disorder before being referred to a specialized center for early detection of psychosis due to possible hallucinatory experiences and delusional ideas...

BACKGROUND: Delusions are a defining and common symptom of psychotic disorders. Recent evidence suggests that subclinical and clinical delusions may represent distinct stages on a phenomenological and biological continuum. However, few studies have tested whether subclinical psychotic experiences are associated with neural changes that are similar to those observed in clinical psychosis. For example, it is unclear if overactivity of the hippocampus, a replicated finding of neuroimaging studies of schizophrenia, is also present in individuals with subclinical psychotic symptoms...

AIM: Early intervention programmes for first episode psychosis (FEP) aim to reduce the duration of untreated psychosis (DUP) and improve functional outcomes. The sustained maintenance of improved outcomes depends largely on patients' adherence to prescribed treatment. This paper examines the prevalence of non-adherence in a cohort of patients with FEP and the sociodemographic and clinical factors associated with non-adherent behaviour. METHODS: The sample included consecutive patients accepted from 2007 to 2012 into the Early Psychosis Intervention Programme (EPIP) in Singapore...

Research in clinical and human neuroscience indicates that important brain mechanisms of self-consciousness are based on the integration of multisensory bodily signals (i.e., bodily self-consciousness: BSC), including signals coming from outside our body (i.e., exteroceptive signals, such as tactile, auditory, and visual information) and the inside of our body (i.e., interoceptive signals). In this chapter, we discuss selected behavioral and neuroimaging studies about how multisensory integration generates and modulates BSC in humans, with particular relevance to parietal mechanisms...

AIM: Valid instruments for the early identification of psychotic experiences (PE) and symptoms in youths are urgently needed for large-scale preventive interventions. A new section of The-Development-and-Well-Being Assessment (DAWBA) measuring child self-reported PE has yet to be validated. The current study aimed to investigate the concurrent validity of DAWBA-based self-reported PE (PE-S) with regard to interview-based measures of PE (PE-I). METHODS: Participants were 1571 (47...

Earlier studies report that although people with borderline personality disorder (BPD) experience symptom reduction in the long term, they continue to have difficulties in work recovery. This nationwide 9-year register-based study (N = 67,075) investigated the long-term labor-market attachment of all individuals diagnosed with BPD during first admission to Danish mental health services in comparison with other psychiatric disorders. Controlling for baseline characteristics and co-occurring secondary psychiatric diagnoses, the BPD group had 32% lower odds (OR = 0...

BACKGROUND: Previous studies have examined the distribution of psychotic like experiences (PLE) with the aim of informing the debate concerning the categorical versus continuous nature of psychosis. We extend this research by subjecting a number of competing models of delusional ideation to validation analysis to further examine previous findings. METHODS: We constructed latent variable models representing the factor structure of delusional ideation reported previously, using self-reported delusional ideation (Peter's Delusional Inventory; PDI) at age 21 in a general population prospective birth cohort study...
