Importance: There is concern about potentially causal effects of tobacco use on psychosis, but epidemiological studies have been less robust in attempts to minimize effects of confounding than studies of cannabis use have been. Objectives: To examine the association of patterns of cigarette and cannabis use with preceding and subsequent psychotic experiences, and to compare effects of confounding across these patterns. Design, Setting, and Participants: This cohort study used data from the Avon Longitudinal Study of Parents and Children, which initially consisted of 14 062 children...

Adrenal insufficiency is divided into three types based on the etiology of its development. In primary adrenal insufficiency, pathology resides in end-organ failure at the level of the adrenal cortex, while in secondary and tertiary adrenal insufficiency, impairment rests in the pituitary gland and hypothalamus, respectively. Regardless of etiology, adrenal insufficiency results in a hypocortisolemic condition. While the relationship between neuropsychiatric symptoms, especially psychosis, and hypercortisolemia has been extensively documented, the development of hypocortisolemia-induced psychosis is less common...

BACKGROUND: Patients with 22q11.2 deletion syndrome (22q11DS) present a high risk of developing psychosis. While clinical and cognitive predictors for the conversion towards a full-blown psychotic disorder are well defined and largely used in practice, neural biomarkers do not yet exist. However, a number of investigations indicated an association between abnormalities in cortical morphology and higher symptoms severities in patients with 22q11DS. Nevertheless, few studies included homogeneous groups of patients differing in their psychotic symptoms profile...

Methamphetamine (METH) is an addictive psychostimulant drug commonly leading to schizophrenia-like psychotic symptoms. Disturbances in glutamatergic neurotransmission have been proposed as neurobiological mechanisms and the α-amino-3 hydroxy-5 methyl-4 isoxazole propionic acid (AMPA) glutamate receptor has been implicated in these processes. Moreover, genetic variants in GRIAs, genes encoding AMPA receptor subunits, have been observed in association with both drug dependence and psychosis. We hypothesized that variation of GRIA genes may be associated with METH dependence and METH-induced psychosis...

REVIEW
Lucie Juliot
Patients with psychosis speak of an uneasy relationship with their body. Between feelings of too little and too much, for them it is a matter of trying to suture an image which is not always unified, a body which they are not always sure they have. The attentive clinician will attempt to support the solutions of each psychotic patient to maintain their body, beyond the death drive which pushes them to tear it apart.

Few studies have investigated the relationship between obsessive-compulsive symptoms (OCS) and clinical variables, and cognition in individuals at ultra high-risk (UHR) for psychosis. The aim of this study was to evaluate the frequency of OCS and their relationship with clinical variables and cognitive functions in individuals at UHR. Eighty-four individuals at UHR for psychosis were administered the Brief Psychiatric Rating Scale, the Yale-Brown Obsession Compulsion Symptom Check List and, the Calgary Depression Scale for Schizophrenia...

BACKGROUND: Both major depressive disorder (MDD) and first episode schizophrenia spectrum (FES) are associated with significant neurocognitive deficits. However, it remains unclear whether the neurocognitive deficits in individuals with FES are more severe if there is comorbid depressive disorder. The aim of this study was to compare the neurocognitive profiles between those with and without full-threshold depressive disorder in FES. METHOD: This study involved secondary analysis of baseline data from a randomized controlled trial of vocational intervention for young people with first-episode psychosis (N = 82; age range: 15-25 years)...

A preregistered systematic review of poststroke psychosis examining clinical characteristics, prevalence, diagnostic procedures, lesion location, treatments, risk factors and outcome. Neuropsychiatric outcomes following stroke are common and severely impact quality of life. No previous reviews have focused on poststroke psychosis despite clear clinical need. CINAHL, MEDLINE and PsychINFO were searched for studies on poststroke psychosis published between 1975 and 2016. Reviewers independently selected studies for inclusion, extracted data and rated study quality...

Poor sleep quality has been repeatedly linked to the entire psychosis continuum, including psychotic-like experiences (PLEs); however, sleep dysfunction is a component of several other psychopathologies that have also been linked to increased risk for PLEs, including depression, anxiety, and post-traumatic stress disorder (PTSD). It has yet to be examined if PLEs are a significant risk factor for poor sleep quality or if this sleep dysfunction is better accounted for by comorbid psychopathology. In 2687 undergraduates, PLEs were evaluated using the positive items of the Prodromal Questionnaire...

BACKGROUND: The 22q11.2 deletion syndrome (22q11DS) is the most common genetic syndrome associated with schizophrenia. The goal of this study was to evaluate longitudinally the interaction between neurocognitive functioning, the presence of subthreshold psychotic symptoms (SPS) and conversion to psychosis in individuals with 22q11DS. In addition, we attempted to identify the specific neurocognitive domains that predict the longitudinal evolution of positive and negative SPS, as well as the effect of psychiatric medications on 22q11DS psychiatric and cognitive developmental trajectories...

BACKGROUND: The impact of psychosis on the treatment of bipolar depression is remarkably understudied. The primary aim of this study was to compare treatment outcomes of bipolar depressed individuals with and without psychosis. The secondary aim was to compare the effect of lithium and quetiapine, each with adjunctive personalized treatments (APTs), in the psychotic subgroup. METHODS: We assessed participants with DSM-IV bipolar depression included in a comparative effectiveness study of lithium and quetiapine with APTs (the Bipolar CHOICE study)...

BACKGROUND: Ethnic minority individuals have an increased risk of developing a psychotic disorder, particularly if they live in areas of ethnic segregation, or low own group ethnic density. The neurobiological mechanisms underlying this ethnic minority associated risk are unknown. We used functional MRI to investigate neural responses to faces of different ethnicity, in individuals of black ethnicity, and a control group of white British ethnicity individuals. METHODS: In total 20 individuals of black ethnicity, and 22 individuals of white British ethnicity underwent a 3T MRI scan while viewing faces of black and white ethnicity...

PURPOSE: The aim of the review is to understand the relationships between loneliness and related psychological and social factors in individuals with psychosis. Loneliness is poorly understood in people with psychosis. Given the myriad of social challenges facing individuals with psychosis, these findings can inform psychosocial interventions that specifically target loneliness in this vulnerable group. METHODS: We adhered to the PRISMA guidelines and systematically reviewed empirical studies that measured loneliness either as a main outcome or as an associated variable in individuals with psychosis...

Activated microglia express the translocator protein (TSPO) on the outer mitochondrial membrane. 18F-PBR111 is a second-generation positron emission tomography (PET) ligand that specifically binds the TSPO, allowing in-vivo visualization and quantification of neuroinflammation. The aim of this study is to evaluate if the test-retest variability of 18F-PBR111 in healthy controls is acceptable to detect a psychosis-associated neuroinflammatory signal in schizophrenia. Methods: Dynamic 90-min 18F-PBR111 scans were obtained in 17 healthy male controls (HC) and 11 male schizophrenia patients during a psychotic episode (SP)...

Systemic lupus erythematosus (SLE) or Lupus is a chronic and idiopathic autoimmune connective tissue disease that involves several organs and organ systems. SLE may lead to a group of psychiatric manifestations, including delirium, anxiety disorders, cognitive dysfunction, mood disorders, and psychosis, which are caused by organic or non-organic factors. In addition, it is thought that the most common cause of neuropsychiatric lupus is corticosteroid use; central nervous system involvement and inflammatory processes also have an important role in the development of psychiatric manifestations...

AIMS: Improving diagnostic batteries to identify individuals at-risk for developing psychotic disorders as early as possible is an ongoing challenge in schizophrenia research. Here, we sought to explore whether metacognition in at-risk of developing psychosis would differ from that of first episode psychosis and unaffected controls and whether dysfunctional metacognitive beliefs would be associated with psychosocial functioning in the clinical groups. METHODS: Twenty-three subjects at-risk of psychosis were compared with a group of 15 first psychotic episode patients and 21 healthy controls with regard to their metacognitive beliefs and psychosocial functioning...

Scientists have long sought to characterize the pathophysiologic basis of schizophrenia and develop biomarkers that could identify the illness. Extensive postmortem and in vivo neuroimaging research has described the early involvement of the hippocampus in the pathophysiology of schizophrenia. In this context, we have developed a hypothesis that describes the evolution of schizophrenia-from the premorbid through the prodromal stages to syndromal psychosis-and posits dysregulation of glutamate neurotransmission beginning in the CA1 region of the hippocampus as inducing attenuated psychotic symptoms and initiating the transition to syndromal psychosis...

BACKGROUND: Although it has been shown that anxiety and depression are associated with increased complications after total joint arthroplasty (TJA), the outcomes of TJA in patients with a history of psychosis are unknown. This study evaluated the influence of bipolar and schizophrenic disorders on complications after TJA, particularly aseptic and septic revisions. METHODS: A retrospective review of 156 TJAs (125 primaries and 31 revisions) was performed at a single institution from 2000 to 2015...
