Synthetic cannabinoids refer to a wide variety of chemicals engineered to bind cannabinoid receptors (CB1 and CB2) and mimic the effects of delta-9-tetrahydrocanabinol. The potential for severe toxicity and limited in vivo data make synthetic cannabinoid intake an important public health and safety concern. Neurologic toxidromes associated with their use include mental status changes, panic attacks, memory distortions, acute psychosis (e.g. paranoia, delusional thoughts), disorganized behavior, and suicidal and homicidal thoughts...

Background: Delusional thinking is one of the hallmark symptoms of schizophrenia. However, the underlying neural substrate for delusions in schizophrenia remains unknown. In an attempt to further our understanding of the neural basis of delusions, we explored gray matter deficits and their clinical associations in first-episode schizophrenia patients with and without delusions. Methods: Twenty-four first-episode schizophrenia patients with delusions and 18 without delusions as well as 26 healthy controls (HC) underwent clinical assessment and whole-brain structural imaging which were acquired a 3...

Individuals with body dysmorphic disorder (BDD) over-attend to perceived defect(s) in their physical appearance, often becoming "stuck" obsessing about perceived flaws and engaging in rituals to hide flaws. These symptoms suggest that individuals with BDD may experience deficits in underlying neurocognitive functions, such as set-shifting and visuospatial organization. These deficits have been implicated as risk and maintenance factors in disorders with similarities to BDD but have been minimally investigated in BDD...

Wilson's disease (WD) is a neurodegenerative disorder due to copper metabolism. Schizophrenia-like psychosis and delusional disorder are rare forms of psychiatric manifestations of WD. The lack of recognition of these signs and symptoms as being attributable to WD often leads to delays in diagnosis and management. Knowledge about relationship of the psychiatric manifestations to WD can help with the administration of adequate management aimed at both the psychiatric issues and underlying WD. The objectives of this article are to review case reports whose subject is the incorrect diagnosis of schizophrenia or schizophrenia-like syndrome in patients with WD and to detail one case of this mismanagement of the disease...

Syndromes of delusional misidentification consist of disordered familiarity and have been reported in diverse diagnoses, including Parkinson's disease. Although the most common delusional misidentification is Capgras syndrome, in which the sufferer believes a familiar person has been replaced by an identical imposter, other forms have been also described. The pathogenesis of delusions of misidentification appears to require dysfunction of or connection to a left cerebral cortical area involved in recognition of familiarity, and also right frontal cortex serving belief evaluation...

BACKGROUND: Monothematic delusional disorders are characterized by a single tenacious belief. They provide a great opportunity to study underlying brain structures in the absence of confounding symptoms that accompany delusions in schizophrenia. Delusional beliefs include persecution, jealousy or somatic delusions including infestation. It is unclear whether specific delusional content is associated with distinct neural substrates. METHODS: We used magnetic resonance imaging in patients presenting with somatic vs...

OBJECTIVE: It still remains unclear whether psychotic features increase the risk of suicidal attempts in major depressive disorder. Thus, we attempted, through a systematic review coupled with a meta-analysis, to elucidate further whether unipolar psychotic depression (PMD) compared to non-PMD presents higher levels of suicidal attempts. METHOD: A systematic search was conducted in PubMed, EMBASE, PsycINFO as well as in various databases of the so-called gray literature for all studies providing data on suicidal attempts in PMD compared to non-PMD, and the results were then subjected to meta-analysis...

We can trace, with high congruence, the clinical syndromes of depression and mania as described over the 20th century in psychiatric textbooks back to 1880 and to the earliest writing of Kraepelin published in 1883. However, this is not the case for Kraepelin's 2 delusional syndromes central to his overall nosology: Dementia Paranoides (later paranoid schizophrenia) and Paranoia. A detailed examination of 28 textbook descriptions of delusional psychoses from 1880 to 1900 reveals a diverse and partially overlapping set of syndromes with an admixture of symptoms and signs that would later be considered indicative of Dementia Paranoides and Paranoia...

Non-bizarre delusion, defined as a false belief possible although highly unlikely, is the main manifestation of delusional disorders, previously known as paranoia. Based on the predominant delusional themes, 5 main subtypes may be described - erotomanic, grandiose, jealous, persecutory, and somatic. We present here 2 main delusional disorders, the De Clérambault syndrome and the Othello syndrome, and another closely related to the previous ones - Folie à deux. In the De Clérambault syndrome, the main delusional theme is erotomanic type, related to passional delirium where the patient has strong sexual feelings towards another person and has the belief that this other person is deeply in love with him or her...

The delusional misidentification syndromes (DMS) are a group of disorders, characterized by patients mistaking the identity of people they know, although they recognize them physically. The term DMS is an umbrella term which may cover disorders whose definition extends to objects other than people, such as animals, places, or familiar material objects. The most common and best known DMS is Capgras syndrome. In this disorder, the misidentification leads to the delusional conviction that a close friend or relative has been replaced by an identical - or almost identical - "double," whose original has disappeared...

Cotard's syndrome is often described as the delusional belief that one is dead or non-existent. However, Jules Cotard's initial description (1880) of the "delusion of negations" was much richer and also involved delusions and claims of immortality and enormity, feelings of damnation, and illusions of bodily dissolution and transformation. Alternatively conceived as an extreme case of depression, hypochondria, or psychosis, the condition is considered rare and remains poorly understood. Cotard himself provided a taxonomy and several explanations for the condition, focusing on its distinction from classical persecutory delusions and suggesting that it could be a kind of reversed grandiosity...

OBJECTIVE: Serious mental illness (SMI; e.g. schizophrenia, schizoaffective disorder, delusional disorder, bipolar disorder, severe major depressive disorder, and psychotic disorders) and Latino ethnicity can produce a compounded health disparity, placing individuals at particularly high risk for excess morbidity and premature mortality. In this study we sought to identify the role of SMI in motivation, participation, and adoption of health behavior change among overweight Latino adults...

Purpose: Post-traumatic stress disorder has been reported in survivors of critical illness. The aim of this study was to investigate the predictors of post-traumatic stress disorder in survivors of critical illness. Materials and methods: Patients attending the intensive care unit (ICU) follow-up clinic completed the UK-Post-Traumatic Stress Syndrome 14-Questions Inventory and data was collected from their medical records. Predictors investigated included age, gender, Apache II score, ICU length of stay, pre-illness psychopathology; delirium and benzodiazepine administration during ICU stay and delusional memories of the ICU stay following discharge...

According to Lacan's theory of schizophrenia (as well as other delirious forms of psychosis), under certain conditions the signifying function breaks down, thus turning the schizophrenic individual's world into one in which a number of events become enigmatic and signal him or her. The schizophrenic individual tries to deal with these signs that besiege him or her either by means of an interpretative attitude (a stable delusional mood) or by apathy. These two types of responses correspond with the stereotypical (and mood) processes by which the schizophrenic individual attempts to avoid the distress provoked by the enigmatic desire of the Other, while simultaneously corresponding with psychosomatic processes of the brain organ...

INTRODUCTION: Cognitive neuropsychiatry has had much success in providing theoretical models for the causal origins of many delusional beliefs. Recently, it has been suggested that some anorexia nervosa patients' beliefs about their own body size should be considered delusions. As such, it seems high time the methods of cognitive neuropsychiatry were turned to modelling the false body size beliefs of anorexics. METHODS: In this paper, I adopt an empiricist approach to modelling the causal origins of false body size beliefs in anorexia...

BACKGROUND: The delusional misidentification syndromes (DMS) include a myriad of discrete but related syndromes, which have wide spectrum anomalies of familiarity. Several misidentification syndromes have been described in the psychiatric literature, the most common of these delusions are: the Capgras syndrome; the Fregoli syndrome; the syndrome of inter-metamorphosis; reduplicative paramnesia; and environmental reduplication. CASE PRESENTATION: The reported case highlights the emergence of late onset first episode psychosis in a Middle Eastern 65-year-old female who has no previous psychiatric history...

Body dysmorphic disorder (BDD) is characterized by excessive preoccupation with a slight or imagined defect in one's physical appearance, believing they look ugly, abnormal or deformed. While the most common preoccupations focus on the skin, hair and nose, any part of the body may be involved. Preoccupations are intrusive, time-consuming and hard to control. Repetitive behaviors are performed in response to the preoccupations. BDD is associated with marked impairment in socio-professional functioning, poor quality of life and high suicide rates...

BACKGROUND: Few studies have examined the trajectories of symptom severity in first episode psychosis (FEP) and their impact on functioning. This study aimed to identify discrete trajectories of positive, negative and general psychopathological symptoms and functioning, determine predictors of the identified symptom trajectories and subsequently investigate the relationship between symptom and functioning trajectories over the 2-year follow-up period. METHODS: Data were extracted from the Singapore Early Psychosis Intervention Programme clinical database...

The aim of the study was to reveal the set of neurobiological parameters informative for individual quantitative prediction of therapeutic response in schizophrenic patients. Correlation and regression analyses of quantitative clinical scores (by Positive And Negative Syndromes Scale - PANSS), together with background EEG spectral power values and four immunological parameters: enzymatic activity of leukocyte elastase and of alpha-1 proteinase inhibitor, as well as serum levels of autoantibodies to common myelin protein and to nerve growth factor, were performed in 50 patients (all females, aged 32...
