The skin and psyche are intimately related with various skin diseases caused by or resulting in psychiatric disturbances. Pruritus is a commonly reported symptom in psychiatric patients, and likewise psychiatric co-morbidities, including anxiety and depression, are frequently seen in chronic pruritus patients. Primary psychodermatologic conditions, such as somatic symptom disorder, dermatitis artefacta, obsessive-compulsive and related disorders (excoriation disorder and prurigo nodularis), delusional infestation, and substance use disorder, can all induce significant pruritus in patients, severely affecting their quality of life...

Objectives The objective of this study was to discuss jinn possession in Muslim culture, and the importance of understanding cultural differences in mental health. Conclusion It is important to understand cultural and religious differences in psychiatry, as it affects the way patients perceive and attribute symptoms. It also helps clinicians to reach an accurate diagnosis and provide appropriate treatments. Beliefs about jinn possession should not automatically be regarded as delusional. In alleged cases of jinn possession, clinicians should consider all the biopsychosocial, cultural and spiritual factors that are unique to the individual...

Influential models of schizophrenia suggest that patients experience incoming stimuli as excessively novel and motivating, with important consequences for hallucinatory experience and delusional belief. However, whether schizophrenia patients exhibit excessive novelty value and whether this interferes with adaptive behaviour has not yet been formally tested. Here, we employed a three-armed bandit task to investigate this hypothesis. Schizophrenia patients and healthy controls were first familiarised with a group of images and then asked to repeatedly choose between familiar and unfamiliar images associated with different monetary reward probabilities...

The present study aimed to explore the latent structure of the 21-item Peters et al. Delusions Inventory (PDI-21) and to test the invariance of its factor structure over time and across samples. The PDI-21 was administered in two samples; one consisting of 1655 undergraduate students investigated in three waves, each separated by six months; and another consisting of 196 outpatients with schizophrenia. Exploratory factor analysis was performed to explore the internal structure of the PDI-21 based on number of beliefs and the grand total scores separately...

OBJECTIVES: The pregnancy periods of peripartum and immediate postpartum represent moments of opportunity to access care. Both prevention and therapeutic management can be offered with a better chance of success during these periods. Our specific Consultation Liaison (CL) team PPUMMA was created in order to respond to the need for early detection of psychopathology and rapid implementation of therapeutic management and preventive measure for mother and child. The importance of urgently intervening "on site" seemed a necessity since duration of hospitalization in maternity wards is very short...

We investigated the clinically derived hypothesis of a relatively high incidence of delusional and psychotic disorders in adolescents with juvenile Myotonic Dystrophy type-1 (DM1). Twenty-seven subjects of age 16-25 with juvenile DM1 and their parents were invited to have a clinical psychiatric interview, and to complete an ASEBA behavior checklist (YSR, ASR, CBCL, and ABCL). We diagnosed a Delusional Disorder in 19% of our patients and a Psychotic Disorder not otherwise specified in another 19%. These two groups of patients had a significantly worse level of clinically defined general functioning...

REVIEW
Annabel Broyd, Ryan P Balzan, Todd S Woodward, Paul Allen
This paper examines the evidence that delusions can be explained within the framework of a neurocognitive model of how the brain assesses certainty. Here, 'certainty' refers to both low-level interpretations of one's environment and high-level (conscious) appraisals of one's beliefs and experiences. A model is proposed explaining how the brain systems responsible for assigning certainty might dysfunction, contributing to the cause and maintenance of delusional beliefs. It is suggested that delusions arise through a combination of perturbed striatal dopamine and aberrant salience as well as cognitive biases such as the tendency to jump to conclusions (JTC) and hypersalience of evidence-hypothesis matches...

BACKGROUND: Safety warnings from health authorities are currently intended to limit the use of antipsychotics (APs) in dementia-related conditions to treat neuropsychiatric symptoms, such as disturbing and/or delusional behaviors. The aim of this study is to investigate prevalence, correlates and trends of AP prescribing among people with dementia between 2010 and 2014 in the French population. METHODS: AP prescribing and associated factors among individuals with AD, mixed dementia and vascular dementia in the French National Alzheimer Database between 2010 and 2014 were analyzed using multivariate generalized estimating equations models (n = 199,549)...

Schizophrenia is a thought disorder characterized by delusional thinking which may be accompanied by hallucinations involving any sensory modality. Schizophrenia may be associated with several neurologic and psychiatric disorders. Also, it may be induced by drugs. In spite of the similarity in psychoses symptomatology, it is unknown if it involves the same underlying neurobiologic mechanisms in those cases. Schizophrenic patients exhibit not only neuroanatomical alterations, but also, distortion of several neurotransmitter systems...

BACKGROUND: Dementia with Lewy bodies (DLB) is the second most frequent diagnosis of progressive degenerative dementia in older people. Delusions are common features in DLB and, among them, Capgras syndrome represents the most frequent disturbance, characterized by the recurrent and transient belief that a familiar person, often a close family member or caregiver, has been replaced by an identical-looking imposter. However, other delusional conditions near to misidentification syndromes can occur in DLB patients and may represent a major psychiatric disorder, although rarely studied systematically...

Psychocutaneous disease, defined in this review as primary psychiatric disease with skin manifestations, is commonly encountered in dermatology. Dermatologists can play an important role in the management of psychocutaneous disease because patients visit dermatology for treatment of their skin problems but often refuse psychiatric intervention. This review describes common psychocutaneous syndromes, including delusional, factitious, obsessive-compulsive and related, and eating disorders, as well as psychogenic pruritus, cutaneous sensory (pain) syndromes, posttraumatic stress disorder, and sleep-wake disorders...

There is a dearth of prospective trials studying treatment response in Persistent Delusional Disorder (PDD) to guide clinical practice. Available retrospective data indicate good response to second-generation antipsychotics (SGAs). We selected the data of patients prescribed either olanzapine or risperidone from a retrospective chart review of PDD (n=455) at our centre. We compared the two groups olanzapine (n =86) versus risperidone (n =280) on dose, drug adherence, response and adverse effects. The two groups were comparable on socio-demographic and clinical characteristics of PDD...

REVIEW
Mary V Seeman
Many individuals with schizophrenia have occasional difficulty defining both to themselves and to others who they truly are. Perhaps for this reason they make attempts to change core aspects of themselves. These attempts may be delusional, but are too often unjustly dismissed as delusional before the potential value of the change is considered. Instead of facilitation, obstacles are placed in the way of hoped-for body modifications or changes of name or of religious faith. This paper discusses the various changes of identity sometimes undertaken by individuals with schizophrenia who may or may not be deluded...

Delusion is central to the conceptualization, definition, and identification of schizophrenia. However, in current classifications, the presence of delusions is neither necessary nor sufficient for the diagnosis of schizophrenia, nor is it sufficient to exclude the diagnosis of some other psychiatric conditions. Partly as a consequence of these classification rules, it is possible for delusions to exist transdiagnostically. In this article, we evaluate the extent to which this happens, and in what ways the characteristics of delusions vary according to diagnostic context...

Erotomania is an uncommon form of delusional disorder in which an individual has an unfounded belief that another is in love with him. Previous case reports have shown that social media networks may play a role in worsening delusional beliefs. We report the case of a 24-year-old male college student that utilized social media to stalk a female college student, resulting in his suspension from school and hospitalization. The student was diagnosed with delusional disorder, erotomanic type, and started on risperidone...
