The role of inner speech in the experience of auditory verbal hallucinations (AVH) and delusions remains unclear. This exploratory study tested for differences in inner speech (assessed via self-report questionnaire) between 89 participants with psychosis and 37 non-clinical controls. We also tested for associations of inner speech with, i) state/trait AVH, ii) AVH-severity; iii) patients' relations with their voices, and; iv) delusion-severity. Persons with psychosis had greater levels of dialogic inner speech, other people in inner speech, and evaluative/motivational inner speech than non-clinical controls...

AIMS: Self-reported psychotic experiences (SRPE) by individuals from the general population are often unconfirmed by clinical interview and referred to as 'false-positive' (FP) SRPE. FP SRPE have been suggested to represent the mildest form of risk along the extended psychosis continuum. However, little is known about their (clinical) outcome and evolution over time. Aims of this study were to prospectively examine, in individuals with FP SRPE, (1) the prevalence of remission, persistence and transition to validated PE at 3-year follow-up; (2) potential baseline psychopathological and psychosocial predictors of persistence of FP SRPE and transition to validated PE; and (3) whether those with persistent FP SRPE and validated PE already differed on psychopathology and psychosocial factors at baseline...

The first episode of psychosis represents a critical period wherein comprehensive early intervention in psychosis (EIP) may alter the course of illness. However, evidence from randomized controlled trials that have examined the impact of comprehensive EIP care on clinical and functional recovery assessed by independent blinded raters is limited. The objective of this study was to conduct a single-blinded multicenter trial comparing comprehensive EIP care and standard care in young patients with first-episode psychosis (FEP) in Japan (J-CAP Study)...

BACKGROUND: No drug treatments are currently licensed for the treatment of borderline personality disorder (BPD). Despite this, people with this condition are frequently prescribed psychotropic medications and often with considerable polypharmacy. Preliminary studies have indicated that mood stabilisers may be of benefit to people with BPD. OBJECTIVE: To examine the clinical effectiveness and cost-effectiveness of lamotrigine for people with BPD. DESIGN: A two-arm, double-blind, placebo-controlled individually randomised trial of lamotrigine versus placebo...

Rising interest in medical marijuana has prompted research into its phytocannabinoid constituents, particularly Δ⁹-tetrahydrocannabinol (THC) and cannabidiol (CBD). Coadministration of CBD with THC has been shown to modulate a number of THC's effects, including its negative stimulus properties (e.g., anxiety, paranoia, psychosis) in a clinical setting. The present series of experiments extended these analyses by examining the ability of CBD to impact the aversive effects of THC as assessed in a combined taste and place conditioning procedure...

Psychotic disorders including schizophrenia are commonly accompanied by cognitive deficits. Recent studies have reported negative genetic correlations between schizophrenia and indicators of cognitive ability such as general intelligence and processing speed. Here we compare the effect of polygenetic risk for schizophrenia (PRSSCZ ) on measures that differ in their relationships with psychosis onset: a measure of current cognitive abilities (the Brief Assessment of Cognition in Schizophrenia, BACS) that is greatly reduced in psychotic disorder patients, a measure of premorbid intelligence that is minimally affected by psychosis onset (the Wide-Range Achievement Test, WRAT); and educational attainment (EY), which covaries with both BACS and WRAT...

Electroencephalography (EEG) has been proposed as a neurophysiological biomarker to delineate psychotic disorders. It is known that increased delta and decreased alpha, which are apparent in psychosis, are indicative of inappropriate arousal state, which leads to reduced ability to attend to relevant information. On this premise, we investigated delta/alpha frequency activity, as this ratio of frequency activity may serve as an effective neurophysiological biomarker. The current study investigated differences in delta/alpha frequency activity, in schizophrenia (SCZ), bipolar I disorder with psychotic features and methamphetamine-induced psychosis...

One of the most widely used measures of psychosis-related symptoms and characteristics is the 74-item Schizotypal Personality Questionnaire (SPQ). Using multidimensional Item Response Theory (bifactor 2-parameter model), we calibrated SPQ items in a sample of 375 youths aged 9-24 years and constructed a fully functional computerized adaptive form of the SPQ on an open-source platform for public use. To assess validity, we used the above parameters to simulate CAT sessions in a separate validation sample (N = 100) using three test-length-based stopping rules: 8 items, 16 items, and 32 items...

BACKGROUND: Keeping individuals on antidepressants after remission or recovery of major depressive disorder is a common strategy to prevent relapse or recurrence. Preventive cognitive therapy (PCT) has been proposed as an alternative to maintenance antidepressant treatment, but whether its addition would allow tapering of antidepressants or enhance the efficacy of maintenance antidepressant treatment is unclear. We aimed to compare the effectiveness of antidepressants alone, with PCT while tapering off antidepressants, or PCT added to antidepressants in the prevention of relapse and recurrence...

BACKGROUND: Schizophrenia is associated with impaired neurodevelopment as indexed by lower premorbid IQ. We examined associations between erythrocyte sedimentation rate (ESR), a marker of low-grade systemic inflammation, IQ, and subsequent schizophrenia and other non-affective psychoses (ONAP) to elucidate the role of neurodevelopment and inflammation in the pathogenesis of psychosis. METHODS: Population-based data on ESR and IQ from 638 213 Swedish men assessed during military conscription between 1969 and 1983 were linked to National Hospital Discharge Register for hospitalisation with schizophrenia and ONAP...

Kynurenic acid (KYNA) is one of the metabolites of evolutionary conserved tryptophan (Trp)/kynurenine (Kyn) metabolic pathway. Elevation of KYNA contributes to development of psychosis in schizophrenia but attenuates neurodegeneration in Drosophila model of Huntington's disease. We have reported that KYNA increased lethality of pupae of wild-type flies, but not of vermilion (v) mutants with impaired formation of Kyn from Trp, suggesting that KYNA toxicity depends on its interaction with downstream Kyn metabolites [i...

Introduction: Oxidative stress and glutathione dysregulation have been implicated in the etiology of schizophrenia. To date, most in vivo studies have investigated alterations in cerebral glutathione levels in patients in which the disorder is already established; however, whether oxidative stress actually predates the onset of psychosis remains unknown. In the current study, we investigated cerebral glutathione levels of antipsychotic-naïve individuals at clinical high risk for psychosis...

BACKGROUND: Mental illness contributes substantially to global disease burden, particularly when illness onset occurs during youth and help-seeking is delayed and/or limited. Yet, few mental health promotion interventions target youth, particularly those with or at high risk of developing mental illness ("at-risk" youth). Community-based translational research has the capacity to identify and intervene upon barriers to positive health outcomes. This is especially important for integrated care in at-risk youth populations...

BACKGROUND: The progression of dementia in people with young-onset dementia (YOD) is relatively unknown. OBJECTIVE: To investigate the progression of dementia and cognitive decline in the three most common subtypes in YOD and to explore which factors are associated with this course. METHODS: The course of dementia was examined in 198 people with YOD. The primary outcomes were cognitive function, as assessed by the Mini-Mental State Examination (MMSE) and dementia severity, as assessed by the Global Deterioration Scale (GDS)...

BACKGROUND: The duration of untreated psychosis (DUP) has been associated with negative outcomes in psychosis; however, few studies have focused on the duration of active psychotic symptoms after commencing treatment (DAT). In this study, we aimed to evaluate the effect of DUP and DAT on functional long-term outcomes (3 years) in patients with early psychosis. METHODS: We evaluated the Scale for the Assessment of Positive Symptoms (SAPS) at frequent intervals for 3 years after presentation to determine the DAT for 307 individuals with first-episode psychosis together with DUP and clinical variables...

BACKGROUND: Many studies having shown significant improvements in non-social and social cognitive performance in smoking FEP patients compared to non-smoking FEP patients. The findings are controversial. This study analyzed the effects of tobacco use on non-social and social cognitive function in a large group of FEP patients and a matched healthy control group. METHODS: A sample of 335 patients with FEP and 253 healthy controls was divided into four subgroups: control tobacco users (CTU), control non-tobacco users (CNTU), patient tobacco users (PTU) and patient non-tobacco users (PNTU)...

BACKGROUND: Antipsychotic agents are often used to treat neuropsychiatric symptoms (NPS) in people with dementia although there is uncertainty about the effectiveness of their long-term use for this indication and concern that they may cause harm, including higher mortality. When behavioural strategies have failed and treatment with antipsychotic drugs is instituted, regular attempts to withdraw them have been recommended in guidelines. Physicians, nurses and families of older people with dementia may be reluctant to stop antipsychotics, fearing deterioration of NPS...
