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by the recurrent and transient belief that a familiar person, often a close family member or caregiver, has been replaced by an identical-looking imposter.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...

Lindsey Gurin, Sonja Blum
Delusions are beliefs that remain fixed despite evidence that they are incorrect. Although the precise neural mechanism of delusional belief remains to be elucidated, there is a predominance of right-hemisphere lesions among patients with delusional syndromes accompanied by structural pathology, suggesting that right-hemisphere lesions, or networks with key nodes in the right hemisphere, may be playing a role. The authors discuss the potential theoretical basis and empiric support for a specific right-hemisphere role in delusion production, drawing on its roles in pragmatic communication; perceptual integration; attentional surveillance and anomaly/novelty detection; and belief updating...

Child maltreatment is a widespread public health problem associated with a range of mental health disorders later in life. In order to effectively address these disorders, there is a need to understand more about the mental health consequences of different types of child maltreatment. This study examines the associations between prospectively substantiated child maltreatment (ages 0-14 y) and reports of hallucinations and delusional experiences at 21 years after birth. As well, we examined 12-month and lifetime psychotic disorders using data from a longitudinal birth cohort...

We report a case of a 57-year-old male patient with intrathecal morphine pump failure who presented with psychosis as part of a clinical presentation of opioid withdrawal. The patient was being treated for chronic back pain with an intrathecal morphine pump for several years. The patient spontaneously started to experience psychotic symptoms which included disorganized thinking, delusional thoughts, paranoia, auditory and visual hallucinations. Upon interrogation of intrathecal pump, it was found not to be functioning, thereby not delivering intrathecal morphine...

BACKGROUND: New psychoactive substances are emerging at an alarming rate. With novel structures and properties they produce unique behavioral characteristics during intoxication. Synthetic cathinones are some of the most common. More and more are presenting to emergency departments due to consequences of use. Aside from isolated reports, little is known about these compounds. OBJECTIVE: Here we review literature pertaining to two common synthetic cathinones, MDPV and alphaPVP, and correlate clinically with guidance on management of intoxications...

Delusions of reference in schizophrenia are thought to result from misattributions of self-relevance to neutral events. Activation of regions within the cortical midline structures (CMS; e.g., medial prefrontal cortex, cingulate cortex, and precuneus) have been previously associated with self-referential processing in schizophrenia patients; however, the specificity of this pattern to individuals with current delusions of reference has yet to be determined. In the present study, we identified functional brain networks that underlie self-referential processing using task-based multivariate functional connectivity...

"Morgellons disease" has been a controversial topic in the history of psychodermatology. The most consensual scientific opinion is that it is a primary psychiatric disorder, particularly, a delusional disorder, although others were also pointed out. Some authors have suggested that it may correspond to a common dermatosis with secondary psychopathology. The Morgellons Research Foundation has advocated that it is "an emerging infectious" entity. This paper intends to critically review the main ideas and controversies, since its first description...

BACKGROUND: Utilization of diagnostic information from national patient registries rests on the quality of the registered diagnoses. We aimed to investigate the agreement and consistency of diagnoses of psychotic and bipolar disorders in the Norwegian Patient Registry (NPR) compared to structured interview-based diagnoses given as part of a clinical research project. METHODS: Diagnostic data from NPR were obtained for the period 01.01.2008-31.12.2013 for all patients who had been included in the Thematically Organized Psychosis (TOP) study between 18...

BACKGROUND: Although there is strong neuroimaging evidence that cortical alterations are a core feature of schizophrenia spectrum disorders, it still remains unclear to what extent such abnormalities occur in monothematic delusional disorders. In individuals with delusional infestation (DI), the delusional belief to be infested with pathogens, previous structural MRI studies have shown prefrontal, temporal, parietal, insular, thalamic and striatal gray matter volume changes. Differential contributions of cortical features of evolutionary and genetic origin (such as cortical thickness, area and folding) which may distinctly contribute to DI pathophysiology are unclear at present...

BACKGROUND: Depressive disorders are a leading cause of the global burden of disease and are associated with high recurrent often continuing morbidity and high excess mortality by suicide and cardiovascular disease. Whilst there are established, effective and cost-effective treatments for depression, their long-term management is often neglected: there is continuing controversy over the case of need for long-term treatment including lifelong treatment and safety issues. OBJECTIVE AND METHODS: In this narrative review, we critically examine the evidence for the effectiveness and safety of lithium salts in the long-term management of unipolar depression...
