AbstractObjectives: To examine the relationship between cognitive deficits, the duration of untreated psychosis (DUP) and positive and negative symptoms in a first episode psychosis sample.Method: We assessed a consecutive sample of first episode psychosis participants from a catchment area service with a comprehensive neuropsychology battery, a family and service-user based measure of DUP and measures of symptomatology.Results: Using correlations and stepwise linear regressions, we found strong relationships between measures of DUP and positive symptomatology. We found that positive and negative symptoms were associated with different time periods within DUP. However, we did not find evidence of a relationship between DUP and cognitive factors.Conclusions: There was no evidence of a relationship between DUP and cognitive deterioration. However, there does appear to be evidence of a relationship between positive symptoms and aspects of DUP. These results highlight the importance of the heterogeneity of DUP and the potential to reduce positive symptoms through early intervention.

BackgroundIncreasing evidence shows attachment security influences symptom expression and adaptation in people diagnosed with schizophrenia and other psychoses.AimsTo describe the distribution of secure and insecure attachment in a cohort of individuals with first-episode psychosis, and to explore the relationship between attachment security and recovery from positive and negative symptoms in the first 12 months.MethodThe study was a prospective 12-month cohort study. The role of attachment, duration of untreated psychosis (DUP), baseline symptoms and insight in predicting and mediating recovery from symptoms was investigated using multiple regression analysis and path analysis.ResultsOf the 79 participants, 54 completed the Adult Attachment Interview (AAI): 37 (68.5%) were classified as insecure, of which 26 (48.1%) were insecure/dismissing and 11 (20.4%) insecure preoccupied. Both DUP and insight predicted recovery from positive symptoms at 12 months. Attachment security, DUP and insight predicted recovery from negative symptoms at 12 months.ConclusionsAttachment is an important construct contributing to understanding and development of interventions promoting recovery following first-episode psychosis.

Background:Network level dysconnectivity has been studied in positive and negative symptoms of schizophrenia. Conceptual disorganization (CD) is a symptom subtype which predicts impaired real-world functioning in psychosis. Systematic reviews have reported aberrant connectivity in formal thought disorder, a construct related to CD. However, no studies have investigated whole-brain functional correlates of CD in psychosis. We sought to investigate brain regions explaining the severity of CD in patients with first-episode psychosis (FEPs) compared with healthy controls (HCs).Methods:We computed whole-brain binarized degree centrality maps of 31 FEPs, 25 HCs and characterized the patterns of network connectivity in the two groups. In FEPs, we related these findings to the severity of CD. We also studied the effect of positive and negative symptoms on altered network connectivity.Results:Compared to HCs, reduced hubness of a right superior temporal gyrus (rSTG) cluster was observed in the FEPs. In patients exhibiting high CD, increased hubness of a medial superior parietal (mSPL) cluster was observed, compared to patients exhibiting low CD. These two regions were strongly correlated with CD scores but not with other symptom scores.Discussion:Our observations are congruent with previous findings of reduced but not increased hubness. We observed increased hubness of mSPL suggesting that cortical reorganization occurs to provide alternate routes for information transfer.Conclusion:These findings provide insight into the underlying neural processes mediating the presentation of symptoms in untreated FEP. A longitudinal tracking of the symptom course will be useful to assess the mechanisms underlying these compensatory changes.

BackgroundIn first-episode schizophrenia, longer duration of untreated psychosis (DUP) predicts poorer outcomes.AimsTo address whether the relationship between DUP and outcome is a direct causal one or the result of association between symptoms and/or cognitive functioning and social functioning at the same time point.MethodSymptoms, social function and cognitive function were assessed in 98 patients with first-episode schizphrenia at presentation and 1 year later.ResultsThere was no significant clinical difference between participants with short and long DUP at presentation. Linear regression analyses revealed that longer DUP significantly predicted more severe positive and negative symptoms and poorer social function at 1 year, independent of scores at presentation. Path analyses revealed independent direct relationships between DUP and social function, core negative symptoms and positive symptoms. There was no significant association between DUP and cognition.ConclusionsLonger DUP predicts poor social function independently of symptoms. The findings underline the importance of taking account of the phenomenological overlap between measures of negative symptoms and social function when investigating the effects of DUP.

Here we report the results of a pilot study investigating the relative and combined effects of a 12 week course of clozapine and CBT in first-episode psychosis patients with prominent ongoing positive symptoms following their initial treatment. Patients from our early psychosis service who met the inclusion criteria () were randomized to one of four treatment groups: clozapine, clozapine plus CBT, thioridazine, or thioridazine plus CBT. The degree of psychopathology and functionality of all participants was measured at baseline then again at 6, 12 and 24 weeks, and the treatment outcomes for each group determined by statistical analysis. A substantial proportion (52%) of those treated with clozapine achieved symptomatic remission, as compared to 35% of those who were treated with thioridazine. Overall, those who received clozapine responded more rapidly to treatment than those receiving the alternative treatments. Interestingly, during the early treatment phase CBT appeared to reduce the intensity of both positive and negative symptoms and thus the time taken to respond to treatment, as well having as a stabilizing effect over time.

Abstract Background The neurodevelopmental model of psychosis was established over 30 years ago; however, the developmental influence on psychotic symptom expression – how age affects clinical presentation in first-episode psychosis – has not been thoroughly investigated. Methods Using generalized additive modeling, which allows for linear and non-linear functional forms of age-related change, we leveraged symptom data from a large sample of antipsychotic-naïve individuals with first-episode psychosis (N = 340, 12–40 years, 1–12 visits), collected at the University of Pittsburgh from 1990 to 2017. We examined relationships between age and severity of perceptual and non-perceptual positive symptoms and negative symptoms. We tested for age-associated effects on change in positive or negative symptom severity following baseline assessment and explored the time-varying relationship between perceptual and non-perceptual positive symptoms across adolescent development. Results Perceptual positive symptom severity significantly decreased with increasing age (F = 7.0, p = 0.0007; q = 0.003) while non-perceptual positive symptom severity increased with age (F = 4.1, p = 0.01, q = 0.02). Anhedonia severity increased with increasing age (F = 6.7, p = 0.00035; q = 0.0003), while flat affect decreased in severity with increased age (F = 9.8, p = 0.002; q = 0.006). Findings remained significant when parental SES, IQ, and illness duration were included as covariates. There were no developmental effects on change in positive or negative symptom severity (all p > 0.25). Beginning at age 18, there was a statistically significant association between severity of non-perceptual and perceptual symptoms. This relationship increased in strength throughout adulthood. Conclusions These findings suggest that as maturation proceeds, perceptual symptoms attenuate while non-perceptual symptoms are enhanced. Findings underscore how pathological brain–behavior relationships vary as a function of development.

AbstractBackground:Negative symptoms have been previously reported during the psychosis prodrome, however our understanding of their relationship with treatment-phase negative symptoms remains unclear.Objectives:We report the prevalence of psychosis prodrome onset negative symptoms (PONS) and ascertain whether these predict negative symptoms at first presentation for treatment.Methods:Presence of expressivity or experiential negative symptom domains was established at first presentation for treatment using the Scale for Assessment of Negative Symptoms (SANS) in 373 individuals with a first episode psychosis. PONS were established using the Beiser Scale. The relationship between PONS and negative symptoms at first presentation was ascertained and regression analyses determined the relationship independent of confounding.Results:PONS prevalence was 50.3% in the schizophrenia spectrum group (n = 155) and 31.2% in the non-schizophrenia spectrum group (n = 218). In the schizophrenia spectrum group, PONS had a significant unadjusted (χ2 = 10.41, P < 0.001) and adjusted (OR = 2.40, 95% CI = 1.11–5.22, P = 0.027) association with first presentation experiential symptoms, however this relationship was not evident in the non-schizophrenia spectrum group. PONS did not predict expressivity symptoms in either diagnostic group.Conclusion:PONS are common in schizophrenia spectrum diagnoses, and predict experiential symptoms at first presentation. Further prospective research is needed to examine whether negative symptoms commence during the psychosis prodrome.

BackgroundIn recent years there has been increasing interest in functional recovery in the early phase of schizophrenia. Concurrently, new remission criteria have been proposed and several studies have examined their clinical relevance for prediction of functional outcome in first-episode psychosis (FEP). However, the longitudinal interrelationship between full functional recovery (FFR) and symptom remission has not yet been investigated. This study sought to: (1) examine the relationships between FFR and symptom remission in FEP over 7.5 years; (2) test two different models of the interaction between both variables.MethodAltogether, 209 FEP patients treated at a specialized early psychosis service were assessed at baseline, 8 months, 14 months and 7.5 years to determine their remission of positive and negative symptoms and functional recovery. Multivariate logistic regression and path analysis were employed to test the hypothesized relationships between symptom remission and FFR.ResultsRemission of both positive and negative symptoms at 8-month follow-up predicted functional recovery at 14-month follow-up, but had limited value for the prediction of FFR at 7.5 years. Functional recovery at 14-month follow-up significantly predicted both FFR and remission of negative symptoms at 7.5 years, irrespective of whether remission criteria were simultaneously met. The association remained significant after controlling for baseline prognostic indicators.ConclusionsThese findings provided support for the hypothesis that early functional and vocational recovery plays a pivotal role in preventing the development of chronic negative symptoms and disability. This underlines the need for interventions that specifically address early psychosocial recovery.
