IntroductionCognitive dysfunction was thought to be one of the core features of schizophrenia. And the executive function of the patients was paid more attention by more and more researchers and clinicians.ObjectivesTo investigate the executive function and the learning ability of the patients with first-episode schizophrenia, and their relationships with psychiatric symptoms.MethodsFifty cases of first-episode schizophrenia patients and fifty age- and gender-matched healthy controls were tested by a computerized version of Tower of London (TOL) test. The scores of the Positive and Negative Syndrome Scale(PANSS) in the group of schizophrenia patients were over 60.ResultsThe numbers of the correct answer [x1 :(14.62 ± 4.12), x2: (14.80 ± 4.70)] during the first session and the second session of the TOL test of the patients group were significantly lower than that of the control group [x1: (17.48 ± 3.79), x2:(18.68 ± 3.19)], and the reaction times [t1: (9.27 ± 4.37) seconds, t2: (9.51 ± 5.58) seconds] of the two sessions of TOL were longer than the control group [t1: (7.28 ± 2.04) seconds, t2: (6.67 ± 1.51) seconds], P < 0.01. For the control group, x2 was significantly greater than x1, and t2 shorter than t1 (P < 0.01), while for the patients group, there was no difference between the performances of the first session and the second session. The scores of TOL in the schizophrenia patients were correlated with the negative symptom score of PANSS (P < 0.05) and were not correlated with the scores of other subscales of PANSS (P > 0.05).ConclusionsThe executive function and the learning ability of schizophrenia are impaired and the cognitive dysfunction is correlated with negative symptoms.

BackgroundHyperprolactinaemia is a common antipsychotic (AP)-induced adverse effect, particularly in female patients.AimsThis meta-analysis examined the efficacy and safety of adjunctive aripiprazole in preventing AP-related hyperprolactinaemia in patients with first-episode schizophrenia.MethodsPubMed, PsycINFO, EMBASE, Cochrane Library, WanFang and China Journal Net databases were searched to identify eligible randomised controlled trials (RCTs). Primary outcomes were the reductions of serum prolactin level and prolactin-related symptoms. Data were independently extracted by two reviewers and analysed using RevMan (V.5.3). Weighted/standardised mean differences (WMDs/SMDs)±95% CIs were reported.ResultsIn the five RCTs (n=400), the adjunctive aripiprazole (n=197) and the control groups (n=203) with a mean of 11.2 weeks of treatment duration were compared. The aripiprazole group had a significantly lower endpoint serum prolactin level in all patients (five RCTs, n=385; WMD: −50.43 ng/mL (95% CI: −75.05 to −25.81), p<0.00001; I2=99%), female patients (two RCTs, n=186; WMD: −22.58 ng/mL (95% CI: −25.67 to −19.49), p<0.00001; I2=0%) and male patients (two RCTs, n=127; WMD: −68.80 ng/mL (95% CI: −100.11 to −37.49), p<0.0001). In the sensitivity analysis for the endpoint serum prolactin level in all patients, the findings remained significant (p<0.00001; I2=96%). The aripiprazole group was superior to the control group in improving negative symptoms as assessed by the Positive and Negative Syndrome Scale (three RCTs, n=213; SMD: −0.51 (95% CI: −0.79 to −0.24), p=0.0002; I2=0%). Adverse effects and discontinuation rates were similar between the two groups.ConclusionsAdjunctive aripiprazole appears to be associated with reduced AP-induced hyperprolactinaemia and improved prolactin-related symptoms in first-episode schizophrenia. Further studies with large sample sizes are needed to confirm these findings.

BackgroundThe outcome of schizophrenia appears to be more favourable than once thought. However, methodological issues, including the reliance on diagnosis at first presentation have limited the validity of outcome studies to date.MethodWe conducted a first-episode follow-up study of 97 patients with DSM-IV schizophrenia over the first 4 years of illness. First presentation and follow-up assessments were compared using paired t tests and a forced-entry regression analysis was used to determine prognostic variables.ResultsThere were significant improvements in positive and negative symptoms and global assessment of functioning between first presentation and follow-up. At first presentation, fewer negative symptoms (t=−3.40, p<0.01), more years spent in education (t=3.25, p<0.01), and a shorter duration of untreated psychosis (DUP) (t=−2.77, p<0.01) significantly predicted a better outcome at follow-up.ConclusionsThe outcome of schizophrenia may not be as pessimistic as once thought and most patients did not display a downward deteriorating course of illness. This study supports the relationship between DUP and outcome beyond the early stages of illness.

Objective: To examine the frequency and predictors of good outcome for patients with first-episode schizophrenia spectrum disorder (SSD). Method: We conducted a 2-year follow-up of a cohort of patients ( n = 547) with first-episode SSD. We evaluated the patients on demographic variables, diagnosis, duration of untreated psychosis (DUP), premorbid functioning, psychotic and negative symptoms, substance abuse, adherence to medication, and service use. ORs were calculated with logistic regression analyses. Results: A total of 369 patients (67%) participated in the follow-up interview. After 2 years, 36% remitted and 17% were considered fully recovered. Full recovery was associated with shorter DUP, better premorbid adjustment, fewer negative symptoms at baseline, no substance abuse at baseline, and adherence to medication and OPUS treatment. Conclusions: Several predictive factors were identified, and focus should be on potentially malleable predictors of outcome, for example, reducing DUP and paying special attention to patients who are unlikely to achieve good outcome, for example, patients with a substance abuse problem and poor premorbid adjustment.

Abstract Cognitive impairment is viewed as a core symptom of schizophrenia (SCZ), but its pathophysiological mechanism remains unclear. White matter (WM) disruption is considered to be a central abnormality that may contribute to cognitive impairment in SCZ patients. However, few studies have addressed the association between cognition and WM integrity in never-treated first-episode (NTFE) patients with SCZ. In this study, we used the MATRICS Consensus Cognitive Battery (MCCB) to evaluate cognitive function in NTFE patients (n = 39) and healthy controls (n = 30), and associated it with whole-brain fractional anisotropy (FA) values obtained via voxel-based diffusion tensor imaging. We found that FA was lower in five brain areas of SCZ patients, including the cingulate gyrus, internal capsule, corpus callosum, cerebellum, and brainstem. Compared with the healthy control group, the MCCB’s total score and 8 out of 10 subscores were significantly lower in NTFE patients (all p < 0.001). Moreover, in patients but not healthy controls, the performance in the Trail Making Test was negatively correlated with the FA value in the left cingulate. Our findings provide evidence that WM disconnection is involved in some cognitive impairment in the early course of SCZ.

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.
