BACKGROUND: The role of onset polarity (OP) in patients with bipolar disorder (BD) has been increasingly investigated over the last few years, for its clinical, prognostic, and therapeutic implications. The present study sought to assess whether OP was associated with specific correlates, in particular with a differential suicidal risk in BD patients. METHODS: A sample of 362 recovered BD patients was dichotomized by OP: depressed (DO) or elevated onset (EO: hypomanic/manic/mixed)...

BACKGROUND AND AIMS: Dual diagnosis commonly occurs among patients with an opioid use disorder. Treatment is ideally performed in an integrated fashion. We present a case which illustrates the complex and challenging psychiatric and medical therapy of such patients in the light of the literature. CASE DESCRIPTION: We report on a 56-year old patient diagnosed with schizophrenia and opioid dependence that suffered both from a risperidone-induced Pisa syndrome and, three years later, an acute psychosis after switching the opioid substitution medication from methadone to slow-release oral morphine due to QT-prolongation...

Unusual interaction behaviors and perceptual aberrations, like those occurring in schizotypy and schizophrenia, may in part originate from impaired remapping of environmental stimuli in the body space. Such remapping is contributed by the integration of tactile and proprioceptive information about current body posture with other exteroceptive spatial information. Surprisingly, no study has investigated whether alterations in such remapping occur in psychosis-prone individuals. Four hundred eleven students were screened with respect to schizotypal traits using the Schizotypal Personality Questionnaire...

There is strong evidence for abnormal salience processing in patients with psychotic experiences. In particular, there are indications that the degree of aberrant salience processing increases with the severity of positive symptoms. The aim of the present study was to elucidate this relationship by means of brain imaging. Functional magnetic resonance imaging was acquired to assess hemodynamic responses during the Salience Attribution Test, a paradigm for reaction time that measures aberrant salience to irrelevant stimulus features...

BACKGROUND: Schizophrenia (SZ) has an estimated heritability of 64-88%, with the higher values based on twin studies. Conventionally, family history of psychosis is the best individual-level predictor of risk, but reliable risk estimates are unavailable for Indian populations. Genetic, environmental, and epigenetic factors are equally important and should be considered when predicting risk in 'at risk' individuals. OBJECTIVE: To estimate risk based on an Indian schizophrenia participant's family history combined with selected demographic factors...

OBJECTIVE: Dopamine supersensitivity psychosis (DSP) is one of the key factors contributing to the development of antipsychotic treatment-resistant schizophrenia (TRS). We investigated the efficacy of blonanserin, an atypical antipsychotic, for patients with TRS and DSP. METHODS: In this 12-month retrospective follow-up study, we investigated the cases of eight consecutive patients with unstable TRS and DSP treated with blonanserin as an add-on therapy. We examined changes in scores for the Brief Psychiatric Rating Scale (BPRS), Clinical Global Impression-Severity of Illness (CGI-S) scale and the Global Assessment of Functioning scale (GAF) during the 12 months after the administration of blonanserin...

Attachment has been identified as one of various possible mechanisms involved in understanding models of psychosis, but measures that reliably and validly assess attachment styles in psychosis are limited. The aim of this study was to identify attachment patterns in psychosis and examine demographic and clinical correlates across attachment groups. Latent profile analysis on attachment data from 588 participants who met criteria for non-affective psychosis was used to classify people into attachment classes...

REVIEW
Stefani O'Donoghue, Laurena Holleran, Dara M Cannon, Colm McDonald
BACKGROUND: The dysconnectivity hypothesis suggests that psychotic illnesses arise not from regionally specific focal pathophysiology, but rather from impaired neuroanatomical integration across networks of brain regions. Decreased white matter organization has been hypothesized to be a feature of psychotic illnesses in general, which is supported by meta-analyses of DTI studies in bipolar disorder and schizophrenia. Although many diffusion MRI studies investigate bipolar disorder and schizophrenia alone, relatively few studies directly compare structural features in these psychotic illnesses...

J Aust, T Bradshaw
: WHAT IS KNOWN ON THE SUBJECT?: Psychosis and the more specific diagnosis of schizophrenia constitute a major psychiatric disorder which impacts heavily on the self-esteem, functioning and quality of life of those affected. A number of mindfulness therapies have been developed in recent years, showing promising results when used with people with the disorder. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: This review of the literature included only randomized controlled trials (RCTs), rather than other typically less robust methods of research (e...

STUDY QUESTION: Is the risk of postpartum psychosis (PPP) increased in women who give birth after IVF treatment compared to after spontaneous conception? SUMMARY ANSWER: The risk of PPP is not higher in the group of women who give birth after IVF treatment compared with women who give birth after spontaneous conception. WHAT IS KNOWN ALREADY: Women who conceive using IVF treatment can experience higher levels of pregnancy-specific distress and are at increased risk of pre-eclampsia, an immune-related condition which in turn has been linked to PPP, as well as other pregnancy and delivery complications, which also serve as PPP risk factors...

BACKGROUND: Methamphetamine psychosis (MAP) symptomatology has been described as indistinguishable from that of schizophrenia (SZ), yet research comparing these two disorders on specific psychotic symptoms such as schneiderian first-rank symptoms (FRS) is lacking. We aimed to determine and compare the occurrence and associations of FRS in patients diagnosed with MAP and with SZ. SAMPLING AND METHOD: Data from SCID-I interviews performed on patients with either a diagnosis of SZ or MAP were compared...

OBJECTIVE: The effect of antipsychotic medication on brain structure remains unclear. Given the prevalence of weight gain as a side-effect, body mass index (BMI) change could be a confounder. METHOD: Patients with first-episode psychosis (n = 78) and healthy controls (n = 119) underwent two 1.5T MRI scans with a 1-year follow-up interval. siena (fsl 5.0) was used to measure whole-brain volume change. Weight and height were measured at both time points. Antipsychotic medication use at baseline and follow-up was converted into chlorpromazine equivalent dose and averaged...

Lisa Bortolotti
In this article I ask whether elaborated and systematized delusions emerging in the context of schizophrenia have the potential for epistemic innocence. Cognitions are epistemically innocent if they have significant epistemic benefits that could not be attained otherwise. In particular, I propose that a cognition is epistemically innocent if it delivers some significant epistemic benefit to a given agent at a given time, and if alternative cognitions delivering the same epistemic benefit are unavailable to that agent at that time...

Recent studies have reported an association between psychopathology and subsequent clinical and functional outcomes in people at ultra-high risk (UHR) for psychosis. This has led to the suggestion that psychopathological information could be used to make prognostic predictions in this population. However, because the current literature is based on inferences at group level, the translational value of the findings for everyday clinical practice is unclear. Here we examined whether psychopathological information could be used to make individualized predictions about clinical and functional outcomes in people at UHR...

OBJECTIVE: Research and clinical translation in schizophrenia is limited by inconsistent definitions of treatment resistance and response. To address this issue, the authors evaluated current approaches and then developed consensus criteria and guidelines. METHOD: A systematic review of randomized antipsychotic clinical trials in treatment-resistant schizophrenia was performed, and definitions of treatment resistance were extracted. Subsequently, consensus operationalized criteria were developed through 1) a multiphase, mixed methods approach, 2) identification of key criteria via an online survey, and 3) meetings to achieve consensus...

Dysfunction of cortical circuitry involving prefrontal cortex, cingulate gyrus and mesial temporal lobe has been implicated in the pathophysiology of psychotic symptoms. 22q11.2 deletion syndrome (22q11DS) is a neurogenetic disorder that comports a 25-fold increased risk of developing psychosis. Morphological changes in the neuroanatomy of this syndrome may represent a biological risk factor for the development of psychosis. The present study explored ratios between cortical volumes and the amygdala. We also explored relationships between these ratios and the eventual development of psychosis in youth with 22q11DS...

Chronic methamphetamine use is associated with executive functioning deficits that suggest dysfunctional cognitive control networks (CCNs) in the brain. Likewise, abnormal connectivity between intrinsic CCNs and default mode networks (DMNs) has also been associated with poor cognitive function in clinical populations. Accordingly, we tested the extent to which methamphetamine use predicts abnormal connectivity between these networks, and whether, as predicted, these abnormalities are compounded in patients with a history of methamphetamine-associated psychosis (MAP)...
