Patients with first-episode psychosis in northern Taiwan: neurocognitive performance and niacin response profile in comparison with schizophrenia patients of different familial loadings and relationship with clinical features. BMC Psychiatry 2024; 24:155. [PMID: 38389072 PMCID: PMC10885443 DOI: 10.1186/s12888-024-05598-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Accepted: 02/08/2024] [Indexed: 02/24/2024] Open
Abstract
BACKGROUND Examining patients with first-episode psychosis (FEP) provides opportunities to better understand the mechanism underlying these illnesses. By incorporating quantitative measures in FEP patients, we aimed to (1) determine the baseline distribution of clinical features; (2) examine the impairment magnitude of the quantitative measures by comparing with external controls and then the counterparts of schizophrenia patients of different familial loadings; and (3) evaluate whether these quantitative measures were associated with the baseline clinical features. METHODS Patients with FEP were recruited from one medical center, two regional psychiatric centers, and two private clinics in northern Taiwan with clinical features rated using the Positive and Negative Syndrome Scale (PANSS) and Personal and Social Performance (PSP) scale. Quantitative measurements included the Continuous Performance Test (CPT), Wisconsin Card Sorting Test (WCST), niacin response abnormality (NRA), and minor physical anomalies and craniofacial features (MPAs). To evaluate the relative performance of the quantitative measures in our FEP patients, four external comparison groups from previous studies were used, including three independent healthy controls for the CPT, WCST, and NRA, respectively, and one group of treatment-resistant schizophrenia patients for the MPAs. Additionally, patients from simplex families and patients from multiplex families were used to assess the magnitude of FEP patients' impairment on the CPT, WCST, and NRA. RESULTS Among the 80 patients with FEP recruited in this study (58% female, mean age = 25.6 years, mean duration of untreated psychosis = 132 days), the clinical severity was mild to moderate (mean PANSS score = 67.3; mean PSP score = 61.8). Patients exhibited both neurocognitive and niacin response impairments (mean Z-scores: -1.24 for NRA, - 1.06 for undegraded d', - 0.70 for degraded d', - 0.32 for categories achieved, and 0.44 for perseverative errors) but did not show MPAs indicative of treatment resistance. Among these quantitative measures, three of the four neurocognitive indices were correlated with the baseline clinical features, whereas NRA did not show such correlation. CONCLUSIONS This FEP study of Taiwanese patients revealed the presence of neurocognitive performance and niacin response and their different relationships with clinical features, rendering this sample useful for future follow-up and incorporation of multiomics investigation.

[PMID: 38277145 PMCID: PMC10818213 DOI: 10.1001/jamanetworkopen.2023.53426] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Accepted: 12/04/2023] [Indexed: 01/27/2024] Open
Abstract
Importance The possible association between the duration of untreated prodromal symptoms (DUPrS) and cognitive functioning in individuals at clinical high risk (CHR) for psychosis remains underexplored. Objective To investigate the intricate interplay between DUPrS, cognitive performance, and conversion outcomes, shedding light on the potential role of DUPrS in shaping cognitive trajectories and psychosis risk in individuals at CHR for psychosis. Design, Setting, and Participants This cohort study of individuals at CHR for psychosis was conducted at the Shanghai Mental Health Center in China from January 10, 2016, to December 29, 2021. Participants at CHR for psychosis typically exhibit attenuated positive symptoms; they were identified according to the Structured Interview for Prodromal Syndromes, underwent baseline neuropsychological assessments, and were evaluated at a 3-year clinical follow-up. Data were analyzed from August 25, 2021, to May 10, 2023. Exposure Duration of untreated prodromal symptoms and cognitive impairments in individuals at CHR for psychosis. Main Outcomes and Measures The primary study outcome was conversion to psychosis. The DUPrS was categorized into 3 groups based on percentiles (33rd percentile for short [≤3 months], 34th-66th percentile for median [4-9 months], and 67th-100th percentile for long [≥10 months]). The DUPrS, cognitive variables, and the risk of conversion to psychosis were explored through quantile regression and Cox proportional hazards regression analyses. Results This study included 506 individuals (median age, 19 [IQR, 16-21] years; 53.6% [n = 271] women). The mean (SD) DUPrS was 7.8 (6.857) months, and the median (IQR) was 6 (3-11) months. The short and median DUPrS groups displayed poorer cognitive performance than the long DUPrS group in the Brief Visuospatial Memory Test-Revised (BVMT-R) (Kruskal-Wallis χ2 = 8.801; P = .01) and Category Fluency Test (CFT) (Kruskal-Wallis χ2 = 6.670; P = .04). Quantile regression analysis revealed positive correlations between DUPrS rank and BVMT-R scores (<90th percentile of DUPrS rank) and CFT scores (within the 20th-70th percentile range of DUPrS rank). Among the 506 participants, 20.8% (95% CI, 17.4%-24.5%) converted to psychosis within 3 years. Cox proportional hazards regression analysis identified lower educational attainment (hazard ratio [HR], 0.912; 95% CI, 0.834-0.998), pronounced negative symptoms (HR, 1.044; 95% CI, 1.005-1.084), and impaired performance on the Neuropsychological Assessment Battery: Mazes (HR, 0.961; 95% CI, 0.924-0.999) and BVMT-R (HR, 0.949; 95% CI, 0.916-0.984) tests as factors associated with conversion. Conclusions and Relevance The finding of this cohort study suggest the intricate interplay between DUPrS, cognitive performance, and conversion risk in individuals at CHR for psychosis. The findings emphasize the importance of considering both DUPrS and cognitive functioning in assessing the trajectory of these individuals.

Abstract
The impact of the duration of untreated psychosis on the outcomes of schizophrenia has been extensively studied. However, there is a notable gap in the current understanding of the relationship between the duration of untreated prodromal symptoms (DUPrS) and the development of psychosis in individuals at clinical high risk (CHR). A sample of 704 individuals with CHR was identified through a structured interview, of who 145 (20.6 %) converted to psychosis (CHR-C) during the 3-year follow-up. The DUPrS was defined as the period between the onset of the first attenuated psychotic positive symptom and the commencement of professional assistance at mental health services. Quantile regression was applied for quantile levels between 0.1 and 0.9, and adjusted for age, sex, and education.The overall sample had a mean DUPrS of 7.1 months. No significant differences were observed in the DUPrS between the CHR-C and non-converter (CHR-NC) groups. Quantile regression analysis highlighted variations in the effects of the DUPrS on clinical variables across the different quantiles. We observed a positive association between DUPrS rank and positive symptoms below the 0.3 quantile, while a positive association between DUPrS rank and negative symptoms above the 0.3 quantile (except 0.7 and 0.9 quantile). A longer DUPrS (> 3 months) was associated with younger age (odds ratio [OR] = 0.948, p = 0.003), a higher proportion of women (OR = 1.474, p = 0.003), higher baseline global function (OR = 1.044, p = 0.003), lower previous global function (OR = 0.921, p < 0.001), and higher negative symptoms (OR = 1.061, p = 0.001). This study sheds light on the pivotal role of DUPrS as a potential intermediary factor in the complex pathway of psychosis.

Paquin-Goulet M, Krishnadas R, Beattie L. A systematic review of factors prolonging or reducing the duration of untreated psychosis for people with psychosis in low- and middle-income countries. Early Interv Psychiatry 2023; 17:1045-1069. [PMID: 37823582 DOI: 10.1111/eip.13466] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Accepted: 09/08/2023] [Indexed: 10/13/2023]
Abstract
AIM This review aims to identify factors that may prolong or reduce the duration of untreated psychosis for people with psychosis in low- and middle-income countries. METHODS Electronic searches of six databases were conducted, to find studies from low- and middle-income countries on people with psychotic disorders provided they statistically measured an association between factors that may prolong or reduce the duration of untreated psychosis. Studies were critically appraised and a narrative synthesis exploring differences between and within studies is presented. A socio-ecological model is used to convey the main findings. RESULTS Thirty studies of 16 473 participants in total were included in this review. Taken together participants were 51.5% male and 48.5% female. Various factors potentially associated with longer duration of untreated psychosis for people with psychosis in low- and middle-income countries were found. Examples of these factors are an insidious mode of onset, greater family stigma and low social class. Other factors, such as marital status, educational level, diagnostic type, predominant symptoms and employment status, yielded inconsistent results. CONCLUSIONS The methodological quality of the included studies limits the conclusions of this review. The results indicate an urgent need for further high-quality research in these countries. The socio-ecological model is a helpful framework for clinicians, scholars, and decision-makers to conceptualize factors that may affect the duration of untreated psychosis, highlight gaps in the literature as well as reflect on potential prevention strategies that may ultimately support early intervention services for people with psychosis in developing countries.

Abstract
The drivers of cognitive change following first-episode psychosis remain poorly understood. Evidence regarding the role of antipsychotic medication is primarily based on naturalistic studies or clinical trials without a placebo arm, making it difficult to disentangle illness from medication effects. A secondary analysis of a randomised, triple-blind, placebo-controlled trial, where antipsychotic-naive patients with first-episode psychotic disorder were allocated to receive risperidone/paliperidone or matched placebo plus intensive psychosocial therapy for 6 months was conducted. A healthy control group was also recruited. A cognitive battery was administered at baseline and 6 months. Intention-to-treat analysis involved 76 patients (antipsychotic medication group: 37; 18.6Mage [2.9] years; 21 women; placebo group: 39; 18.3Mage [2.7]; 22 women); and 42 healthy controls (19.2Mage [3.0] years; 28 women). Cognitive performance predominantly remained stable (working memory, verbal fluency) or improved (attention, processing speed, cognitive control), with no group-by-time interaction evident. However, a significant group-by-time interaction was observed for immediate recall (p = 0.023), verbal learning (p = 0.024) and delayed recall (p = 0.005). The medication group declined whereas the placebo group improved on each measure (immediate recall: p = 0.024; ηp2 = 0.062; verbal learning: p = 0.015; ηp2 = 0.072 both medium effects; delayed recall: p = 0.001; ηp2 = 0.123 large effect). The rate of change for the placebo and healthy control groups was similar. Per protocol analysis (placebo n = 16, medication n = 11) produced similar findings. Risperidone/paliperidone may worsen verbal learning and memory in the early months of psychosis treatment. Replication of this finding and examination of various antipsychotic agents are needed in confirmatory trials. Antipsychotic effects should be considered in longitudinal studies of cognition in psychosis.Trial registration: Australian New Zealand Clinical Trials Registry ( http://www.anzctr.org.au/ ; ACTRN12607000608460).

Schizophr Res 2023; 254:54-61. [PMID: 36801514 DOI: 10.1016/j.schres.2023.02.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Revised: 01/19/2023] [Accepted: 02/05/2023] [Indexed: 02/17/2023]
Abstract
Emerging evidence suggests that the duration of risk symptoms (DUR) may have an impact on clinical outcomes in clinical high-risk for psychosis (CHRP) participants. To explore this hypothesis, we performed a meta-analysis on studies that examined DUR in CHR-P individuals in relation to their clinical outcomes. This review was conducted in accordance with the PRISMA guidelines and the protocol was registered with PROSPERO on 16th April 2021 (ID no. CRD42021249443). Literature searches were conducted using PsycINFO and Web of Science in March and November 2021, for studies reporting on DUR in CHR-P populations, in relation to transition to psychosis or symptomatic, functional, or cognitive outcomes. The primary outcome was transition to psychosis, while the secondary outcomes were remission from CHR-P status and functioning at baseline. Thirteen independent studies relating to 2506 CHR-P individuals were included in the meta-analysis. The mean age was 19.88 years (SD = 1.61) and 1194 individuals (47.65 %) were females. The mean length of DUR was 23.61 months (SD = 13.18). There was no meta-analytic effect of DUR on transition to psychosis at 12-month follow-up (OR = 1.000, 95%CI = 0.999-1.000, k = 8, p = .98), while DUR was related to remission (Hedge's g = 0.236, 95%CI = 0.014-0.458, k = 4, p = .037). DUR was not related to baseline GAF scores (beta = -0.004, 95%CI = -0.025-0.017, k = 3, p = .71). The current findings suggest that DUR is not associated with transition to psychosis at 12 months, but may impact remission. However, the database was small and further research in this area is required.

Abstract
Duration of untreated psychosis (DUP) is defined as the time from the onset of psychotic symptoms until the first treatment. Studies have shown that longer DUP is associated with poorer response rates to antipsychotic medications and impaired cognition, yet the neurobiologic correlates of DUP are poorly understood. Moreover, it has been hypothesized that untreated psychosis may be neurotoxic. Here, we conducted a comprehensive review of studies that have examined the neurobiology of DUP. Specifically, we included studies that evaluated DUP using a range of neurobiologic and imaging techniques and identified 83 articles that met inclusion and exclusion criteria. Overall, 27 out of the total 83 studies (32.5%) reported a significant neurobiological correlate with DUP. These results provide evidence against the notion of psychosis as structurally or functionally neurotoxic on a global scale and suggest that specific regions of the brain, such as temporal regions, may be more vulnerable to the effects of DUP. It is also possible that current methodologies lack the resolution needed to more accurately examine the effects of DUP on the brain, such as effects on synaptic density. Newer methodologies, such as MR scanners with stronger magnets, PET imaging with newer ligands capable of measuring subcellular structures (e.g., the PET ligand [11C]UCB-J) may be better able to capture these limited neuropathologic processes. Lastly, to ensure robust and replicable results, future studies of DUP should be adequately powered and specifically designed to test for the effects of DUP on localized brain structure and function with careful attention paid to potential confounds and methodological issues.

Abstract
OBJECTIVE Determining the extent to which relationships between duration of untreated psychosis (DUP) and outcome endure longitudinally across the lifetime course of psychotic illness requires prospective, systematic studies of epidemiologically representative incidence cohorts across decades. Transience, persistence, or heterogeneity in associations between DUP and distinct outcome domains are yet to be investigated over such time frames. METHODS Prospective, sequential follow-up studies of an epidemiologically representative first-episode psychosis incidence cohort in Ireland were conducted at 6 months and 4, 8, 12, and 20 years (N=171). Linear mixed-model analyses were applied to determine whether prospective associations of DUP with symptoms, functioning, and quality of life were consistent or varied across psychotic illness trajectory over a 20-year period. Evaluations included time, DUP quartile, and DUP quartile-by-time interaction effects. RESULTS Prospective, sequential follow-ups showed positive and negative symptoms, function, and quality of life to exhibit distinct trajectories of improvement in relation to shorter DUP. Despite heterogeneity in course and relationship to premorbid features, associations between shorter DUP and greater improvement were still evident 20 years after the first psychotic episode. Across the long-term course of psychotic illness, trajectories of association between shorter DUP and better outcome differed between domains of psychopathology, functionality, and quality of life. Nevertheless, such associations with shorter DUP were sustained for at least 20 years. CONCLUSIONS These profiles indicate that while associations between DUP and long-term outcome can vary according to the domain of outcome, they are sustained across decades in a manner that could not be fully accounted for in terms of premorbid features or lead-time bias.

Abstract
BACKGROUND The prevalence of suicidal ideation (SI) and behavior (SB) among people suffering from psychotic disorders is a public health issue. Most suicide attempts (SAs) occur before or during the early phases of first-episode psychosis (FEP). Improving knowledge about the suicide risk in the early stages is essential to develop therapeutic and prevention strategies. We conducted a systematic review to investigate an association between neurocognitive impairments or a history of impulsive behavior and SI or SB among patients with FEP. METHOD PRISMA guidelines were followed. Ten databases were searched using MeSH terms or key-words related to FEP, impulsivity or cognitive functioning measures and SI or SB, without restrictions for study design or length of follow-up. Included studies evaluated at least one cognitive function with neuropsychological tests or validated questionnaires, or provided records of impulsive behavior. RESULTS Twenty one research papers were included from databases, bibliographic references or expert opinions. Among patients with FEP, seven studies showed more pronounced neuropsychological impairments, especially regarding attention, processing speed, executive functioning and theory of mind in patients that had attempted suicide. No association was found between cognitive impairments on neuropsychological tests and SI. Previous non-suicidal impulsive behaviors were associated with SAs and suicide. CONCLUSION Our review suggests an association between neurocognitive impairments and SAs among patients with FEP. Records of impulsive behavior are also associated with SB in that population. Further research on the neuropsychology of FEP is necessary to identify how these impairments facilitate SB and evaluate their potential utility as therapeutic targets.

Abstract
Cognitive impairment is one of the core symptoms of schizophrenia. Quite a number of systematic reviews were published related to cognitive impairment in people with schizophrenia (PWS). This umbrella review, therefore, aimed at reviewing and synthesizing the findings of systematic reviews related to domains of cognition impaired and associated factors in PWS. We searched four electronic databases. Data related to domains, occurrence, and associated factors of cognitive impairment in PWS were extracted. The quality of all eligible systematic reviews was assessed using A MeaSurement Tool to Assess methodological quality of systematic Review (AMSTAR) tool. Results are summarized and presented in a narrative form. We identified 63 systematic reviews fulfilling the eligibility criteria. The included reviews showed that PWS had lower cognitive functioning compared to both healthy controls and people with affective disorders. Similar findings were reported among psychotropic free cases and people with first episode psychosis. Greater impairment of cognition was reported in processing speed, verbal memory, and working memory domains. Greater cognitive impairment was reported to be associated with worse functionality and poor insight. Cognitive impairment was also reported to be associated with childhood trauma and aggressive behaviour. According to our quality assessment, the majority of the reviews had moderate quality. We were able to find a good number of systematic reviews on cognitive impairment in PWS. The reviews showed that PWS had higher impairment in different cognitive domains compared to healthy controls and people with affective disorders. Impairment in domains of memory and processing speed were reported frequently.

Abstract
AIMS to study the differences in cognitive functioning in patients and controls. In addition, study the influence of symptoms, cannabis consumption, chlorpromazine doses, DUP and IQ in cognitive performance in patients, both in the total sample and divided by gender. METHODS 70 first episode psychosis patients and 63 healthy controls (HC) participated in the study and were assessed with the MATRICS battery and the Vocabulary subtest of WAIS-IV. Symptoms in FEP patients were evaluated with the Emsley factors of the PANSS scale. RESULTS patients showed lower scores than controls in all cognitive domains studied. There were no significant differences between FEP men and FEP women, but we found gender differences in favour of women in processing speed, working memory and composite total scored domains in the HC group. Finally, symptoms and Chlorpromazine doses showed an influence on cognitive performance in the total FEP sample. When splitting the sample by gender, positive symptoms may be more detrimental to women's cognitive functioning, while disorganized symptoms may play the most important role in cognitive performance in men. CONCLUSIONS patients showed worse cognitive performance in all cognitive domains compared to healthy controls. In our FEP sample, gender does not seem to influence cognitive performance measured with the MATRICS. Severity of symptoms influences positively in cognitive performance. The dose of Chlorpromazine and symptoms are influential variables to be taken into account in cognition rehabilitation programs.

Abstract
AIM To explore if the entire duration of active psychosis (DAP) is related to neurocognitive performance at baseline and at 3-year follow-up in patients with first episode psychosis (FEP). METHODS DAP was estimated for 481 FEP patients. A neuropsychological battery was administered to measure neurocognitive specific domains, and a global indicator of neurocognitive impairment (global deficits score, GDS) was calculated. According to the DAP quartiles, four subgroups were formed, and these were compared. In addition, a logistic regression analysis was carried out to predict neurocognitive impairment at 3-year follow-up. RESULTS FEP patients with the longest DAP (more than 18.36 months) presented a more severe global neurocognitive impairment evidenced in their GDS, both at baseline (F = 5.53; p˂ .01) and at 3-year follow-up (F = 4.16; p˂ .01). Moreover, a subgroup of participants with DAP between 7.40 and 18.36 months showed a specific attentional decline over the 3-year follow-up (F = 3.089; p˂ .05).The logistic regression model showed that sex (Wald = 7.29, p < .010), premorbid adjustment (Wald = 7.24, p < .010), attention (Wald = 12.10, p < .001), verbal memory (Wald = 16.29, p < .001) and visual memory (Wald = 9.41, p < .010) were significant predictors of neurocognitive impairment 3 years after the FEP. The variables composing the DAP were not significant predictors in this model. CONCLUSIONS DAP seems to be related to global neurocognitive impairment in FEP patients. These findings contribute in several ways to our understanding of the effects of active psychosis on the brain, and provide the basis for future research.

Abstract
BACKGROUND Validated clinical prediction models of short-term remission in psychosis are lacking. Our aim was to develop a clinical prediction model aimed at predicting 4-6-week remission following a first episode of psychosis. METHOD Baseline clinical data from the Athens First Episode Research Study was used to develop a Support Vector Machine prediction model of 4-week symptom remission in first-episode psychosis patients using repeated nested cross-validation. This model was further tested to predict 6-week remission in a sample of two independent, consecutive Danish first-episode cohorts. RESULTS Of the 179 participants in Athens, 120 were male with an average age of 25.8 years and average duration of untreated psychosis of 32.8 weeks. 62.9% were antipsychotic-naïve. Fifty-seven percent attained remission after 4 weeks. In the Danish cohort, 31% attained remission. Eleven clinical scale items were selected in the Athens 4-week remission cohort. These included the Duration of Untreated Psychosis, Personal and Social Performance Scale, Global Assessment of Functioning and eight items from the Positive and Negative Syndrome Scale. This model significantly predicted 4-week remission status (area under the receiver operator characteristic curve (ROC-AUC) = 71.45, P < .0001). It also predicted 6-week remission status in the Danish cohort (ROC-AUC = 67.74, P < .0001), demonstrating reliability. CONCLUSIONS Using items from common and validated clinical scales, our model significantly predicted early remission in patients with first-episode psychosis. Although replicated in an independent cohort, forward testing between machine learning models and clinicians' assessment should be undertaken to evaluate the possible utility as a routine clinical tool.

Abstract
PURPOSE Psychotic disorders develop during mid-adolescence through early adulthood, with the initial few months a "critical period" offering the greatest promise for recovery. However, the duration of untreated psychosis is typically over a year. This study aimed to identify aspects of care episodes contributing to delays in diagnosis of a first psychotic episode. METHODS Study subjects included 161 adolescents and young adults referred to a first episode psychosis treatment program. We captured the various ways that people who experience a severe mental illness engage in treatment using standardized interviews with patients and informants (e.g., family member) and medical record review. RESULTS A psychotic disorder diagnosis was not given for 38% of subjects at their initial episode of care. Time to first care episode was virtually the same for subjects that did and did not receive a psychosis diagnosis; 50% within 1 month and 84% within 6 months. Compared to initial care episodes with a psychosis diagnosis, those without a psychosis diagnosis less often involved emergency services (80% vs. 38%, respectively; p value = 1 × 10-7) and more often outpatient primary care (6% vs. 18%; p value = .032) and mental health (32% vs. 49%; p value = .045) services. However, dangerousness indicators were similar (29% vs. 28%; p value = 1). Dangerousness indicators increased to 54% (p value = .002) by the time of eventual diagnosis for those requiring multiple care episodes. CONCLUSIONS Clinicians were important contributors to delays in diagnosis and treatment of psychosis. Interventions targeting outpatient health care providers may be fruitful in reducing the duration of untreated psychosis.

Abstract
China accounts for 17% of the global disease burden attributable to mental, neurological and substance use disorders. As a country undergoing profound societal change, China faces growing challenges to reduce the disease burden caused by psychiatric disorders. In this review, we aim to present an overview of progress in neuroscience research and clinical services for psychiatric disorders in China during the past three decades, analysing contributing factors and potential challenges to the field development. We first review studies in the epidemiological, genetic and neuroimaging fields as examples to illustrate a growing contribution of studies from China to the neuroscience research. Next, we introduce large-scale, open-access imaging genetic cohorts and recently initiated brain banks in China as platforms to study healthy brain functions and brain disorders. Then, we show progress in clinical services, including an integration of hospital and community-based healthcare systems and early intervention schemes. We finally discuss opportunities and existing challenges: achievements in research and clinical services are indispensable to the growing funding investment and continued engagement in international collaborations. The unique aspect of traditional Chinese medicine may provide insights to develop a novel treatment for psychiatric disorders. Yet obstacles still remain to promote research quality and to provide ubiquitous clinical services to vulnerable populations. Taken together, we expect to see a sustained advancement in psychiatric research and healthcare system in China. These achievements will contribute to the global efforts to realize good physical, mental and social well-being for all individuals.

Nkire N, Scully PJ, Browne DJ, Baldwin PA, Kingston T, Owoeye O, Kinsella A, O'Callaghan E, Russell V, Waddington JL. Systematic comparison of duration of untreated illness versus duration of untreated psychosis in relation to psychopathology and dysfunction in the Cavan-Monaghan first episode psychosis study (CAMFEPS). Eur Neuropsychopharmacol 2021; 47:20-30. [PMID: 33823369 DOI: 10.1016/j.euroneuro.2021.03.003] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2020] [Revised: 02/25/2021] [Accepted: 03/01/2021] [Indexed: 01/22/2023]
Abstract
This study systematically compared duration of untreated illness (DUI) with duration of untreated psychosis (DUP) in prediction of impairment at first-episode psychosis and investigated the extent to which these relationships are influenced by premorbid features. The Cavan-Monaghan First Episode Psychosis Study ascertained cases of first-episode psychosis in rural Ireland via all routes to care with limited variations in socioeconomic milieu. Cases were evaluated for DUI and DUP and assessed clinically for psychopathology, neuropsychology, neurology, insight and quality of life, together with premorbid features. Analyses then determined prediction of clinical assessments by DUI versus DUP. The study population consisted of 163 cases of first episode psychosis, among which 74 had a schizophrenia spectrum disorder. Shorter DUI but not DUP predicted less severe positive and general symptoms, while shorter DUP and particularly DUI predicted less severe negative symptoms; neither shorter DUP nor shorter DUI predicted less severe cognitive impairment or fewer neurological soft signs; shorter DUP and DUI predicted increased quality of life; shorter DUI but not DUP predicted greater insight. Only prediction of quality of life was weakened by consideration of premorbid features. Results were generally similar across the two diagnostic groupings. The present findings systematically delineate associations with DUI versus DUP across domains of impairment in first episode psychosis. They suggest that DUI may reflect a more insidious process than DUP and that reduction in DUI may be associated with more consistent and broader diminutions in impairment than for DUP.

Abstract
BACKGROUND The domains of functioning affected by first episode of psychosis (FEP) could be analysed as forming a network of interacting or even reinforcing elements. The reasons why longer duration of untreated psychosis (DUP) might be related to higher disability are not still clear. The aim of the present study is to evaluate how different areas of functioning are inter-related according to the length of DUP in patients with FEP, with a particular focus on studying the relative influence of each other according to lengthy delays in initial treatment. METHOD 441 participants in an epidemiological and intervention program of first episode psychosis (PAFIP) were included in our study. Functioning problems at baseline were assessed with the WHO Disability Assessment Schedule (DAS). Three networks of functioning domains have been estimated according to the length of DUP. RESULTS All the DAS items took part in the different networks. We have not found differences across the edge weights in the short, medium and long DUP groups. The domains "social withdrawal", "participation in the household activities", "general interest and information", and "low level of activity" seem to act as bridge items with other areas of functioning in people with longer DUP. CONCLUSIONS Our results could have clinical implications for patients with longer DUP, in which case, social withdrawal, household activities, level of activity and general interest in the world around them, could be high-priority target areas of treatment, since they seem to be mediating the relation between others areas of functioning.

Abstract
The idea that a longer duration of untreated psychosis (DUP) leads to poorer outcomes has contributed to extensive changes in mental health ser-vices worldwide and has attracted considerable research interest over the past 30 years. However, the strength of the evidence underlying this notion is unclear. To address this issue, we conducted an umbrella review of available meta-analyses and performed a random-effects meta-analysis of primary studies. MEDLINE, Web of Science, PsycINFO and EMBASE were searched from inception to September 3, 2020 to identify relevant meta-analyses of studies including patients with schizophrenia spectrum disorders, first-episode psychosis, or affective and non-affective psychosis. Thirteen meta-analyses were included, corresponding to 129 individual studies with a total sample size of 25,657 patients. We detected potential violations of statistical assumptions in some of these meta-analyses. We therefore conducted a new random-effects meta-analysis of primary studies. The association between DUP and each outcome was graded according to a standardized classification into convincing, highly suggestive, suggestive, weak, or non-significant. At first presentation, there was suggestive evidence for a relationship between longer DUP and more severe negative symptoms (beta=-0.07, p=3.6×10-5 ) and higher chance of previous self-harm (odds ratio, OR=1.89, p=1.1×10-5 ). At follow-up, there was highly suggestive evidence for a relationship between longer DUP and more severe positive symptoms (beta=-0.16, p=4.5×10-8 ), more severe negative symptoms (beta=-0.11, p=3.5×10-10 ) and lower chance of remission (OR=2.16, p=3.0×10-10 ), and suggestive evidence for a relationship between longer DUP and poorer overall functioning (beta=-0.11, p=2.2×10-6 ) and more severe global psychopathology (beta=-0.16, p=4.7×10-6 ). Results were unchanged when analysis was restricted to prospective studies. These effect sizes are clinically meaningful, with a DUP of four weeks predicting >20% more severe symptoms at follow-up relative to a DUP of one week. We conclude that DUP is an important prognostic factor at first presentation and predicts clinically relevant outcomes over the course of illness. We discuss conceptual issues in DUP research and methodological limitations of current evidence, and provide recommendations for future research.

Abstract
Schizophrenia and other psychoses display a common profile of mild to moderate cognitive deficits that are associated with poor functional outcomes. Cognitive impairment is usually evaluated by neuropsychological assessment, and interview-based measures with good psychometric properties and high utility for clinical practice are now available. However, the extent to which a set of clinical criteria can be used as proxy measures of cognitive deficits in this population has not been tested. This study aimed to examine the empirical validity of a set of clinical criteria for cognitive impairment associated with psychosis (CIAPs). Ninety-eight patients with non-pure affective psychosis and 50 healthy-matched controls were included. The CIAPs criteria were empirically tested against antecedent, concurrent and outcome validators and by means of a neuropsychological evaluation based on MATRICS Consensus Cognitive Battery (MCCB). The CIAPs criteria showed strong associations with outcomes and certain antecedent validators and moderate associations with concurrent validators. The CIAPs criteria achieved superior neuropsychological validity compared to current DSM 5 criteria for schizophrenia, the B-criterion of DSM 5 schizophrenia or a combination of both criteria. Cognitive impairment associated with psychosis can be clinically assessed and is a useful tool for clinical practice and predicting outcomes of schizophrenia and related psychosis.

Effect of delaying treatment of first-episode psychosis on symptoms and social outcomes: a longitudinal analysis and modelling study. Lancet Psychiatry 2020; 7:602-610. [PMID: 32563307 PMCID: PMC7606908 DOI: 10.1016/s2215-0366(20)30147-4] [Citation(s) in RCA: 60] [Impact Index Per Article: 15.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2020] [Revised: 03/31/2020] [Accepted: 04/01/2020] [Indexed: 11/21/2022]
Abstract
BACKGROUND Delayed treatment for first episodes of psychosis predicts worse outcomes. We hypothesised that delaying treatment makes all symptoms more refractory, with harm worsening first quickly, then more slowly. We also hypothesised that although delay impairs treatment response, worse symptoms hasten treatment, which at presentation mitigates the detrimental effect of treatment delay on symptoms. METHODS In this longitudinal analysis and modelling study, we included two longitudinal cohorts of patients with first-episode psychosis presenting to English early intervention services from defined catchments: NEDEN (recruiting 1003 patients aged 14-35 years from 14 services between Aug 1, 2005, and April 1, 2009) and Outlook (recruiting 399 patients aged 16-35 years from 11 services between April 1, 2006, and Feb 28, 2009). Patients were assessed at baseline, 6 months, and 12 months with the Positive and Negative Symptom Scale (PANSS), Calgary Depression Scale for Schizophrenia, Mania Rating Scale, Insight Scale, and Social and Occupational Functioning Assessment Scale. Regression was used to compare different models of the relationship between duration of untreated psychosis (DUP) and total symptoms at 6 months. Growth curve models of symptom subscales tested predictions arising from our hypotheses. FINDINGS We included 948 patients from the NEDEN study and 332 patients from the Outlook study who completed baseline assessments and were prescribed dopamine antagonist antipsychotics. For both cohorts, the best-fitting models were logarithmic, describing a curvilinear relationship of DUP to symptom severity: longer DUP predicted reduced treatment response, but response worsened more slowly as DUP lengthened. Increasing DUP by ten times predicted reduced improvement in total symptoms (ie, PANSS total) by 7·339 (95% CI 5·762 to 8·916; p<0·0001) in NEDEN data and 3·846 (1·689 to 6·003; p=0·0005) in Outlook data. This was true of treatment response for all symptom types. Nevertheless, longer DUP was not associated with worse presentation for any symptoms except depression in NEDEN (coefficients 0·099 [95% CI 0·033 to 0·164]; p=0·0028 in NEDEN and 0·007 [-0·081 to 0·095]; p=0·88 in Outlook). INTERPRETATION Long DUP was associated with reduced treatment response across subscales, consistent with a harmful process upstream of individual symptoms' mechanisms; response appeared to worsen quickly at first, then more slowly. These associations underscore the importance of rapid access to a comprehensive range of treatments, especially in the first weeks after psychosis onset.

Advancing study of cognitive impairments for antipsychotic-naïve psychosis comparing high-income versus low- and middle-income countries with a focus on urban China: Systematic review of cognition and study methodology. Schizophr Res 2020; 220:1-15. [PMID: 32269004 PMCID: PMC8985208 DOI: 10.1016/j.schres.2020.01.026] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/26/2019] [Revised: 01/25/2020] [Accepted: 01/30/2020] [Indexed: 02/08/2023]
Abstract
BACKGROUND Comparing the course of antipsychotic-naïve psychosis in low- and middle-income countries (LMIC) may help to illuminate core pathophysiologies associated with this condition. Previous reviews-primarily from high-income countries (HIC)-identified cognitive deficits in antipsychotic-naïve, first-episode psychosis, but did not examine whether individuals with psychosis with longer duration of untreated psychosis (DUP > 5 years) were included, nor whether LMIC were broadly represented. METHOD A comprehensive search of PUBMED from January 2002-August 2018 identified 36 studies that compared cognitive functioning in antipsychotic-naïve individuals with psychosis (IWP) and healthy controls, 20 from HIC and 16 from LMIC. RESULTS A key gap was identified in that LMIC study samples were primarily shorter DUP (<5 years) and were primarily conducted in urban China. Most studies matched cases and controls for age and gender but only 9 (24%) had sufficient statistical power for cognitive comparisons. Compared with healthy controls, performance of antipsychotic-naïve IWP was significantly worse in 81.3% (230/283) of different tests of cognitive domains assessed (90.1% in LMIC [118/131] and 73.7% [112/152] in HIC). CONCLUSIONS Most LMIC studies of cognition in antipsychotic-naïve IWP adopted standardized procedures and, like HIC studies, found broad-based impairments in cognitive functioning. However, these LMIC studies were often underpowered and primarily included samples typical of HIC: primarily male, young-adult, high-school educated IWP, in their first episode of illness with relatively short DUP (<5 years). To enhance understanding of the long-term natural course of cognitive impairments in untreated psychosis, future studies from LMIC should recruit community-dwelling IWP from rural areas where DUP may be longer.

Hippocampal glutamate and hippocampus subfield volumes in antipsychotic-naive first episode psychosis subjects and relationships to duration of untreated psychosis. Transl Psychiatry 2020; 10:137.

Abstract
Evidence points toward a relationship between longer duration of untreated psychosis (DUP) and worse long-term outcomes in patients with first episode psychosis (FEP), but the underlying neurobiology remains poorly understood. Proton magnetic resonance spectroscopy studies have reported altered hippocampus glutamatergic neurotransmission, and structural MRI as reported hippocampal atrophy that may be associated with memory impairment in schizophrenia. Here, we quantify left hippocampus glutamate (Glx) and left hippocampus subfield volumes in 54 antipsychotic-naive FEP and 41 healthy controls (HC), matched on age, sex, and parental occupation. While there were no significant group difference in Glx levels, hippocampal Glx levels were significantly higher in those who underwent a long DUP (>12 months) compared to those with a short DUP, and compared to HC. Compared to HC, FEP had significantly reduced whole hippocampus volume, as well as of CA1, CA4, granule cell layer, subiculum, and presubiculum subfields. Smaller whole hippocampal volume, as well as CA1, molecular layer, subiculum, presubiculum, and hippocampal tail volumes were significantly associated with longer DUP. However, we found no significant association between hippocampal Glx levels and hippocampal volume or subfields, suggesting that these alterations are not related, or their relationship does not follow a linear pattern. However, our results strongly suggest that one or several pathophysiological processes underlie the DUP. Importantly, our data highlight the critical need for reducing the DUP and for early pharmacological intervention with the hope to prevent structural deficits and, hopefully, improve clinical outcomes.

Abstract
Both research and care have focused on first episodes of psychosis (FEPs) as a way to address the issue of early stages of schizophrenia and to reduce the duration of untreated psychosis. The objective of this study was to explore specifically the lived experience of FEP from the point of view of patients and their families by applying a metasynthetic approach, including a systematic review of the literature and analyses of qualitative studies on the subject. This metasynthesis follows thematic synthesis procedures. Four databases were systematically searched for qualitative studies reporting FEP from the patient or family's perspective. Article quality was assessed with the Critical Appraisal Skills Program. Thematic analysis was used to identify key themes and synthesize them. Thirty-eight articles were included, covering data from 554 participants (378 patients and 176 relatives). Three themes emerged from the analyses: (1) When and how does a FEP start? (2) What are its negative and positive aspects? (3) How do patients and families recount FEPs? Our results found important discrepancies between the experiences of patients and those of their families, especially regarding positive aspects. In light of the confusion reported by patients and notable in our results, we also discuss the gap between the name, FEP, and the lived experience of patients and family members in order to explore its practical implications.
