[PMID: 32924144 DOI: 10.1111/jcpp.13322] [Citation(s) in RCA: 87] [Impact Index Per Article: 29.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/19/2020] [Revised: 06/20/2020] [Accepted: 07/31/2020] [Indexed: 12/15/2022]
Abstract
BACKGROUND The clinical high-risk state for psychosis (CHR-P) paradigm has facilitated the implementation of psychosis prevention into clinical practice; however, advancements in adolescent CHR-P populations are less established. METHODS We performed a PRISMA/MOOSE-compliant systematic review of the Web of Science database, from inception until 7 October 2019, to identify original studies conducted in CHR-P children and adolescents (mean age <18 years). Findings were systematically appraised around core themes: detection, prognosis and intervention. We performed meta-analyses (employing Q statistics and I 2 test) regarding the proportion of CHR-P subgroups, the prevalence of baseline comorbid mental disorders, the risk of psychosis onset and the type of interventions received at baseline. Quality assessment and publication bias were also analysed. RESULTS Eighty-seven articles were included (n = 4,667 CHR-P individuals). Quality of studies ranged from 3.5 to 8 (median 5.5) on a modified Newcastle-Ottawa scale. Detection: Individuals were aged 15.6 ± 1.2 years (51.5% males), mostly (83%) presenting with attenuated positive psychotic symptoms. CHR-P psychometric accuracy improved when caregivers served as additional informants. Comorbid mood (46.4%) and anxiety (31.4%) disorders were highly prevalent. Functioning and cognition were impaired. Neurobiological studies were inconclusive. PROGNOSIS Risk for psychosis was 10.4% (95%CI: 5.8%-18.1%) at 6 months, 20% (95%CI: 15%-26%) at 12 months, 23% (95%CI: 18%-29%) at 24 months and 23.3% (95%CI: 17.3%-30.7%) at ≥36 months. INTERVENTIONS There was not enough evidence to recommend one specific treatment (including cognitive behavioural therapy) over the others (including control conditions) to prevent the transition to psychosis in this population. Randomised controlled trials suggested that family interventions, cognitive remediation and fish oil supplementation may improve cognition, symptoms and functioning. At baseline, 30% of CHR-P adolescents were prescribed antipsychotics and 60% received psychotherapy. CONCLUSIONS It is possible to detect and formulate a group-level prognosis in adolescents at risk for psychosis. Future interventional research is required.

Abstract
Background During the last decades, a renewed interest for negative symptoms (NS) was brought about by the increased awareness that they interfere severely with real-life functioning, particularly when they are primary and persistent. Methods In this guidance paper, we provide a systematic review of the evidence and elaborate several recommendations for the conceptualization and assessment of NS in clinical trials and practice. Results Expert consensus and systematic reviews have provided guidance for the optimal assessment of primary and persistent negative symptoms; second-generation rating scales, which provide a better assessment of the experiential domains, are available; however, NS are still poorly assessed both in research and clinical settings. This European Psychiatric Association (EPA) guidance recommends the use of persistent negative symptoms (PNS) construct in the context of clinical trials and highlights the need for further efforts to make the definition of PNS consistent across studies in order to exclude as much as possible secondary negative symptoms. We also encourage clinicians to use second-generation scales, at least to complement first-generation ones. The EPA guidance further recommends the evidence-based exclusion of several items included in first-generation scales from any NS summary or factor score to improve NS measurement in research and clinical settings. Self-rated instruments are suggested to further complement observer-rated scales in NS assessment. Several recommendations are provided for the identification of secondary negative symptoms in clinical settings. Conclusions The dissemination of this guidance paper may promote the development of national guidelines on negative symptom assessment and ultimately improve the care of people with schizophrenia.

Abstract
AbstractPsychiatric imaging, in particular functional imaging techniques such as functional magnetic resonance imaging (fMRI) are potentially powerful tools to explore the neurophysiological basis of the early stages of psychosis. Despite this impressive growth, neuroimaging has yet to become an established as diagnostic instrument this area, partly as a result of significant heterogeneity across the findings from research studies. The present review aims to: (i) assess the determinants of inconsistencies in the results from neuroimaging studies of the early stages of psychosis; and (ii) suggest approaches for future imaging research in this field that may reduce methodological differences between studies.

Abstract
AbstractBackground:We investigated whether psychosis risk symptoms predicted psychiatric service use using seven-year register follow-up data.Methods:Our sample included 715 adolescents aged 15–18, referred to psychiatric care for the first time. Psychosis risk symptoms were assessed with the Prodromal Questionnaire (PQ) at the beginning of the treatment. We assessed the power of the overall PQ as well as its positive, negative, general, and disorganized psychosis risk symptom factors in predicting prolonged service use. Baseline psychiatric diagnoses (grouped into 7 categories) were controlled for. Based on both inpatient and outpatient psychiatric treatment after baseline, adolescents were divided into three groups of brief, intermittent, and persistent service use.Results:Stronger symptoms on any PQ factor as well as the presence of a mood disorder predicted prolonged service use. All of the PQ factors remained significant predictors when adjusted for baseline mood disorder and multimorbidity.Conclusions:In a prospective follow-up of a large sample using comprehensive mental health records, our findings indicate that assessing psychosis risk symptoms in clinical adolescent settings at the beginning of treatment could predict long-term need for care beyond diagnostic information. Our findings replicate the previous findings that positive psychosis risk symptoms are unspecific markers of severity of psychopathology. Also psychosis risk symptoms of the negative, disorganization, and general clusters are approximately as strongly associated with prolonged psychiatric service use in the upcoming years.

Abstract
Twenty percent of individuals at clinical high risk for psychosis (CHR-P) develop the disorder within 2 years. Extensive research has explored the factors that differentiate those who develop psychosis and those who do not, but the results are conflicting. The current systematic review and meta-analysis comprehensively addresses the consistency and magnitude of evidence for non-purely genetic risk and protective factors associated with the risk of developing psychosis in CHR-P individuals. Random effects meta-analyses, standardized mean difference (SMD) and odds ratio (OR) were used, in combination with an established stratification of evidence that assesses the association of each factor and the onset of psychotic disorders (from class I, convincing evidence to class IV weak evidence), while controlling for several types of biases. A total of 128 original controlled studies relating to 26 factors were retrieved. No factors showed class I-convincing evidence. Two further factors were associated with class II-highly suggestive evidence: attenuated positive psychotic symptoms (SMD = 0.348, 95% CI: 0.280, 0.415) and global functioning (SMD = -0.291, 95% CI: -0.370, -0.211). There was class III-suggestive evidence for negative psychotic symptoms (SMD = 0.393, 95% CI: 0.317, 0.469). There was either class IV-weak or no evidence for all other factors. Our findings suggest that despite the large number of putative risk factors investigated in the literature, only attenuated positive psychotic symptoms, global functioning, and negative psychotic symptoms show suggestive evidence or greater for association with transition to psychosis. The current findings may inform the refinement of clinical prediction models and precision medicine in this field.

Abstract
BACKGROUND The 22q11.2 deletion syndrome (22q11DS) is one of the highest known risk factors for schizophrenia and recent findings have highlighted the clinical relevance of ultra-high risk (UHR) criteria in this population. However, studies in other at-risk populations have shown that the presence of negative symptoms (NS) is also of clinical relevance in predicting transition to psychosis. The present study examined in detail the presence and course of NS in 22q11DS, as well as their value in predicting transition to psychosis. METHODS A total of 111 participants aged between 8 and 33 years were assessed with the Structured Interview for Psychosis-Risk Syndromes (SIPS). A follow-up assessment was available for 89 individuals. RESULTS Core NS of at least moderate severity were present in 50.5% of the sample and were more severe in individuals meeting UHR criteria. They predominantly remained stable over time and their emergence between baseline and follow-up assessment was associated with significant functional decline. Some NS were significant predictors of conversion to psychosis and the emergence/persistence of psychosis risk. CONCLUSIONS Altogether, these findings highlight that NS are core manifestations of psychosis in individuals with 22q11DS that strongly impact global functioning. The presence of NS should be a primary target of early therapeutic intervention in this population.

Abstract
Objective Youth at clinical high risk (CHR) for psychosis often demonstrate significant negative symptoms, which have been reported to be predictive of conversion to psychosis and a reduced quality of life but treatment options for negative symptoms remain inadequate. Therefore, we conducted a systematic review and network meta-analysis of all intervention studies examining negative symptom outcomes in youth at CHR for psychosis. Method The authors searched PsycINFO, Medline, Embase, CINAHL, and EBM from inception to December 2016. Studies were selected if they included any intervention that reported follow-up negative symptoms in youth at CHR for psychosis. Treatment comparisons were evaluated using both pairwise and network meta-analyses. Due to the differences in negative symptom scales the effect sizes were reported as the standardized mean difference (SMD). Results Of 3027 citations, 32 studies met our inclusion criteria, including a total of 2463 CHR participants. The null hypothesis was not rejected for any of the 11 treatments. N-methyl-D-aspartate-receptor (NMDAR) modulators trended toward a significant reduction in negative symptoms compared to placebo (SMD = -0.54; 95% CI = -1.09 to 0.02; I2 = 0%, P = .06). In respective order of descending effectiveness as per the treatment hierarchy, NMDAR modulators were more effective than family therapy, need-based interventions, risperidone, amisulpride, cognitive behavioral therapy, omega-3, olanzapine, supportive therapy, and integrated psychological interventions. Conclusions Efficacy and effectiveness were not confirmed for any negative symptom treatment. Many studies had small samples and the majority were not designed to target negative symptoms.

Abstract
OBJECTIVE Based on the results of 5-year follow-up study, to describe the dynamics of psychopathological symptoms in young patients with non-psychotic forms of mental diseases met the criteria of ultra-high risk for schizophrenia who received preventive psychopharmacotherapy. MATERIAL AND METHODS The study included 32 young men, aged 16--25 years, presented with the symptoms of ultra-high risk of schizophrenia during the first hospitalization in 2009--2011. Follow-up was carried out in 2014--2015 (mean follow-up 5.79±0.36 years). According to ICD-10, patients were stratified into 3 groups: mood disorders, personality disorders and schizotypal disorders. RESULTS AND CONCLUSION According to the characteristics of subsequent development of these disorders, four types were singled out: mechanisms of the development of acute sensitive delusions (I), interpretative delusions (II), catatonic disorganization (III) and cognitive disorders pathognomonic for schizophrenia spectrum disorders (IV). Correlations between these types and nosologic disorders and their different reversibility under treatment were found. These types can be considered as predictors of outcome over the follow-up period.

Abstract
An important focus of studies of individuals at ultra-high risk (UHR) for psychosis has been to identify biomarkers to predict which individuals will transition to psychosis. However, the majority of individuals will prove to be resilient and go on to experience remission of their symptoms and function well. The aim of this study was to investigate the possibility of using structural MRI measures collected in UHR adolescents at baseline to quantitatively predict their long-term clinical outcome and level of functioning. We included 64 UHR individuals and 62 typically developing adolescents (12-18 years old at recruitment). At six-year follow-up, we determined resilience for 43 UHR individuals. Support Vector Regression analyses were performed to predict long-term functional and clinical outcome from baseline MRI measures on a continuous scale, instead of the more typical binary classification. This led to predictive correlations of baseline MR measures with level of functioning, and negative and disorganization symptoms. The highest correlation (r = 0.42) was found between baseline subcortical volumes and long-term level of functioning. In conclusion, our results show that structural MRI data can be used to quantitatively predict long-term functional and clinical outcome in UHR individuals with medium effect size, suggesting that there may be scope for predicting outcome at the individual level. Moreover, we recommend classifying individual outcome on a continuous scale, enabling the assessment of different functional and clinical scales separately without the need to set a threshold.

Brain development in adolescents at ultra-high risk for psychosis: Longitudinal changes related to resilience. NEUROIMAGE-CLINICAL 2016; 12:542-549.

Abstract
Background The main focus of studies of individuals at ultra-high risk for psychosis (UHR) has been on identifying brain changes in those individuals who will develop psychosis. However, longitudinal studies have shown that up to half of UHR individuals are resilient, with symptomatic remission and good functioning at follow-up. Yet little is known about brain development in resilient individuals. Therefore, the aim of this study was to investigate differences in brain development between resilient and non-resilient individuals. Methods A six-year longitudinal structural MRI study was performed with up to three scans per individual. The final sample consisted of 48 UHR individuals and 48 typically developing controls with a total of 225 MRI-scans, aged 12–20 years at the time of the first MRI-scan and matched for age, gender and number of follow-up scans. At six-year follow-up, 35 UHR individuals were divided in resilient (good functional outcome) and non-resilient (poor functional outcome) subgroups, defined by the modified Global Assessment of Functioning. The main outcome measures were developmental changes in MR-based measures of cortical and subcortical anatomy. Results We found widespread differences in volume of frontal, temporal and parietal cortex between resilient and non-resilient individuals. These were already present at baseline and remained stable over development (12–24 years). Furthermore, there were differences in the development of cortical surface area in frontal regions including cingulate gyrus. Conclusions Developmental differences may reflect compensatory neural mechanisms, where better functioning in resilient individuals leads to less tissue loss over development. Is brain development different between resilient and non-resilient UHR individuals? We performed a longitudinal MRI study with up to three scans per individual. Resilience was defined by functional outcome at 6-year follow-up. Widespread differences were found, primarily in volume and cortical surface area. Developmental differences may reflect compensatory neural mechanisms.

Identifying children and adolescents at ultra high risk of psychosis in Italian neuropsychiatry services: a feasibility study. Eur Child Adolesc Psychiatry 2016; 25:91-106. [PMID: 25925786 DOI: 10.1007/s00787-015-0710-8] [Citation(s) in RCA: 35] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/19/2014] [Accepted: 04/07/2015] [Indexed: 12/20/2022]
Abstract
The past 20 years have seen the evolution of the construct of a clinical high-risk (hereafter, HR) state for psychosis. This construct is designed to capture the pre-psychotic phase. Some aspects of this approach, such as its feasibility in children and adolescents, are still under investigation. In the present study, we address the feasibility of implementing prodrome clinics for HR individuals within the framework of Italy's national child and adolescent neuropsychiatry services and the clinical relevance of a HR diagnosis in this population. Using the Comprehensive Assessment of At-Risk Mental States (CAARMS) to identify help-seeking patients meeting at least one HR criterion at baseline (HR+), we recruited 50 subjects for a feasibility study. The results obtained show that the Italian version of the CAARMS is easily administrable, causing patients no substantial discomfort. The prevalence of HR+ in our cohort was 44 %, which increased by an additional 18 % when negative symptoms were considered as an experimental inclusion criterion (HRNeg). The HR+ subjects were significantly more impaired in their social and occupational functioning than their HR- peers (subjects not at HR). The cumulative 1-year transition risk of psychosis of the HR+ group was 26.7 %. When the HRNeg group was added, the 1-year transition risk was 17.3 %. We suggest that administration of the CAARMS to children and adolescents with putative prodromal psychosis is feasible and that this assessment can easily be integrated into existing Italian neuropsychiatry services although clinicians should interpret results with caution as results in this age group still have to be replicated.

Abstract
Abnormalities in the brain's attention network may represent early identifiable neurobiological impairments in individuals at increased risk for schizophrenia or bipolar disorder. Here, we provide evidence of dysfunctional regional and network function in adolescents at higher genetic risk for schizophrenia or bipolar disorder [henceforth higher risk (HGR)]. During fMRI, participants engaged in a sustained attention task with variable demands. The task alternated between attention (120 s), visual control (passive viewing; 120 s), and rest (20 s) epochs. Low and high demand attention conditions were created using the rapid presentation of two- or three-digit numbers. Subjects were required to detect repeated presentation of numbers. We demonstrate that the recruitment of cortical and striatal regions are disordered in HGR: relative to typical controls (TC), HGR showed lower recruitment of the dorsal prefrontal cortex, but higher recruitment of the superior parietal cortex. This imbalance was more dramatic in the basal ganglia. There, a group by task demand interaction was observed, such that increased attention demand led to increased engagement in TC, but disengagement in HGR. These activation studies were complemented by network analyses using dynamic causal modeling. Competing model architectures were assessed across a network of cortical-striatal regions, distinguished at a second level using random-effects Bayesian model selection. In the winning architecture, HGR were characterized by significant reductions in coupling across both frontal-striatal and frontal-parietal pathways. The effective connectivity analyses indicate emergent network dysconnection, consistent with findings in patients with schizophrenia. Emergent patterns of regional dysfunction and dysconnection in cortical-striatal pathways may provide functional biological signatures in the adolescent risk-state for psychiatric illness.

Abstract
BACKGROUND The clinical high-risk state for psychosis (HRP) is associated with an enhanced probability of developing a psychotic episode over a relatively short period of time. However, the extent to which different diagnostic types of illness develop remains unclear. METHODS A systematic review was performed to identify studies of HRP participants reporting International Classfication of Diseases/Diagnostic and Statistical Manual of Mental Disorders diagnostic outcomes at follow-up. Demographic, clinical, and methodological variables were extracted from each publication or obtained directly from its authors. A meta-analysis was performed of transition to schizophrenic (SP) or affective psychoses (AP) and to specific diagnostic categories. Statistical heterogeneity and small study bias were assessed, and meta-regressions were performed. RESULTS Twenty-three studies were retrieved, including a total of 2182 HRP participants, 560 (26%) of them developed a frank psychotic disorder over the follow-up time (mean = 2.35 y). Among HRP participants who developed psychosis, 73% were diagnosed with SP and only 11% with AP (Risk Ratio, RR = 5.43, 95% CI from 3.35 to 8.83). The specific transition risk to ICD/DSM schizophrenia was of 15.7% (over 2.35y). Heterogeneity was statistically significant and moderate in magnitude. Use of basic symptoms criteria in the baseline clinical assessment was associated with a further increase in the proportion progressing to SP vs AP (RR = 17.1). There was no evidence of publication bias and the sensitivity analysis confirmed robustness of the above results. CONCLUSIONS The HRP state is heterogeneous in term of longitudinal diagnoses; however, the current HRP diagnostic criteria appear strongly biased toward an identification of early phases of SP rather than AP.

Abstract
CONTEXT During the past 2 decades, a major transition in the clinical characterization of psychotic disorders has occurred. The construct of a clinical high-risk (HR) state for psychosis has evolved to capture the prepsychotic phase, describing people presenting with potentially prodromal symptoms. The importance of this HR state has been increasingly recognized to such an extent that a new syndrome is being considered as a diagnostic category in the DSM-5. OBJECTIVE To reframe the HR state in a comprehensive state-of-the-art review on the progress that has been made while also recognizing the challenges that remain. DATA SOURCES Available HR research of the past 20 years from PubMed, books, meetings, abstracts, and international conferences. STUDY SELECTION AND DATA EXTRACTION Critical review of HR studies addressing historical development, inclusion criteria, epidemiologic research, transition criteria, outcomes, clinical and functional characteristics, neurocognition, neuroimaging, predictors of psychosis development, treatment trials, socioeconomic aspects, nosography, and future challenges in the field. DATA SYNTHESIS Relevant articles retrieved in the literature search were discussed by a large group of leading worldwide experts in the field. The core results are presented after consensus and are summarized in illustrative tables and figures. CONCLUSIONS The relatively new field of HR research in psychosis is exciting. It has the potential to shed light on the development of major psychotic disorders and to alter their course. It also provides a rationale for service provision to those in need of help who could not previously access it and the possibility of changing trajectories for those with vulnerability to psychotic illnesses.

Abstract
Attempts to identify people at imminent risk of psychotic disorder have been made during the past 20 years. High-risk criteria have been developed, and despite findings of a recent decline in the rate of onset of psychosis associated with these criteria, people identified still have a significantly greater risk, compared with the general population. Intervention studies in this group indicate that psychological treatments and fish oil appear to be just as effective as antipsychotics. Future research should refine risk factors for psychosis and examine outcomes other than psychosis. Research is also needed into what harms and benefits are associated with making the high-risk criteria into a formal diagnosis.

Abstract
INTRODUCTION Prevention of psychosis has become a major objective of modern clinical psychiatry. An increasing number of new services have been established in Europe and in the world. The OASIS team has become an established model where clinical practice and research are fully integrated in the field of preventative interventions in psychosis. METHOD Comprehensive analysis of different clinical and service measures describing the 2001-2011 implementation of the OASIS team. RESULTS Over the last decade, the OASIS team has received a total of 1102 referrals, mostly young males from ethnic minorities. After the assessment, 35% were diagnosed with an At Risk Mental State (ARMS) while 32% were already psychotic. Within the ARMS, 70% met the inclusion criteria for the attenuated psychotic symptoms subgroup, 1% met the inclusion criteria for the genetic deterioration syndrome, 9% met inclusion criteria for a brief and self-limited intermittent psychotic episode and the others met inclusion criteria for more than one subgroup. Most of them had at least one comorbid diagnosis, mainly relating to anxiety and depressive domains. The majority of the OASIS clients received cognitive behavioural therapy alone or in combination with antidepressants/antipsychotics. Over the 2-year follow-up time, 44 subjects (15.2%) developed a frank psychotic episode. CONCLUSIONS The OASIS service represents one of the largest and most established prodromal services in the world. The burden of research evidence and the translational impact produced on the clinical practice support the OASIS as a model for the development of similar services.
