Does operational diagnosis of schizophrenia significantly impact intellectual deficits in psychotic disorders?

Background Evidence suggests that, as a group, patients with schizophrenia have intellectual deficits that may precede the manifestation of psychotic symptoms; however, how successfully intelligence tests are able to discriminate schizophrenia from other psychotic disorders has yet to be investigated in detail. Methods Using Wechsler Adult Intelligence Scale – Revised (WAIS‐R) data for 55 inpatients with schizophrenia and 28 inpatients with non‐schizophrenic psychotic disorders (NSPD) (schizophreniform disorder, brief psychotic disorder, delusional disorder, psychotic disorder due to a general medical condition, and psychotic disorders not otherwise specified), intelligence performance was compared between schizophrenia and NSPD and among different subtypes of schizophrenia. Results There were no significant differences in intelligence quotient (IQ), verbal IQ (VIQ) and performance IQ (PIQ) discrepancy, and subtest scores of WAIS‐R between the patients with schizophrenia and those with NSPD. These diagnostic groups were not discriminated well by any WAIS‐R variables. Schizophrenia patients with prominent negative symptoms, on the other hand, had a significantly larger IQ discrepancy (VIQ > PIQ) than those without prominent negative symptoms and NSPD patients. Intelligence performance in schizophrenia did not differ with respect to diagnostic subtypes and longitudinal courses. Conclusions The current study failed to show diagnostic usefulness of WAIS‐R in discriminating schizophrenia and other psychoses. A diagnosis of schizophrenia does not significantly impact intellectual deficits in psychotic disorders.     

Clinical course and outcome of cycloid psychotic disorder: a three-year prospective study

The course and outcome of cycloid psychotic disorder was explored by means of a prospective three-year follow-up of a sample of patients fulfilling the diagnostic criteria for the disorder provided by Perris & Brockington, compared to patients with a diagnosis of affective or schizoaffective disorder. The most striking difference between cycloids and affectives was the lack of manic episodes during the follow-up period in the former group. Moreover, the mean age at onset was lower in cycloids. No difference between these patient groups was observed with regard to outcome. Compared to schizoaffectives, cycloids showed several differences in the clinical picture during the index episode, and their symptomatological pattern was more consistent from one episode to another during the follow-up. Moreover, the outcome of cycloids was significantly more favourable than that of schizodepres-sives.     

舒必利与氯丙嗪合用治疗慢性精神分裂症阴性症状的对照研究

目的 探讨舒必利与氯丙嗪及舒必利,氯丙嗪治疗慢性精神分裂症阴性症状的疗效。方法 将60例以阴性症状为主要表现的慢性精神分裂症病人随机分为舒必利合并氯丙嗪组(研究组)及舒必利组,氯丙嗪3个组。用临床疗效评定标准和BPRS量表评定疗效。结果 研究组的显效率(显进 痊愈)明显比氯丙嗪组及舒必利组高,x~2检验P<0.05提示舒必利合并氯丙嗪治疗比单一用药疗效显著。舒必利组氯丙嗪组显效率比较无显著性差异(P<0.05)。结论 舒必利合并氯丙嗪治疗慢性精神分裂症阴性症状的疗效比单一用药更好,副作用更少。     

住院精神分裂症患者十年前后用药情况对比分析

目的对十年前后精神分裂症患者用药情况的变化进行调查分析.方法对十年前后两个五年段的各500份符合精神分裂症诊断标准的病历进行回顾性调查,并对各项指标进行对比分析.结果两组折算用药剂量经t检验差异无显著性(P>0.05);两组合并用药、合并抗胆碱药及疗效经χ2检验差异有显著性(P<0.01);十年后非典型抗精神病药物氯氮平在临床上的应用比例明显增大并上升为首位.结论十年前后两组抗精神病药的应用发生了明显变化,疗效好、副作用轻的非典型抗精神病药的应用比例明显增加.     

Socioeconomic status and the effectiveness of treatment for first‐episode psychosis

ObjectiveTo assess whether patient socioeconomic status (SES) moderates the effectiveness of coordinated specialty care for first‐episode psychosis and to investigate possible mechanisms.Data SourcesA secondary analysis of data from the RAISE‐ETP Trial, which was conducted from 2010‐2014.Study DesignRAISE‐ETP was a cluster‐randomized trial comparing a coordinated specialty care (CSC) intervention called NAVIGATE with usual community care. We constructed a patient SES index based on parental education, parental occupational prestige, and race/ethnicity. After identifying correlates of SES, we used OLS regression analysis to estimate treatment effects on the major study outcomes across quartiles of the index. We also examined whether correlates of SES including the duration of untreated psychosis (DUP), and participation in NAVIGATE might account for the observed difference in effectiveness of CSC by SES.Principal FindingsThe trial sample had a similar SES distribution to the US population, and SES was positively correlated with all mental health outcomes and several potential moderators at baseline. CSC substantially improved the main trial outcomes compared to community care for patients in the highest SES quartile but had small and statistically insignificant benefits for the remaining 75% of patients. Intervention participation rates and several potential moderators did not explain this disparity.ConclusionsCSC may be more effective for high‐SES patients with early psychosis than low‐SES patients. Additional research is needed to understand why CSC is less effective for low‐SES patients and to develop methods to increase effectiveness for this subgroup.     

情感性精神障碍事件相关电位变异与自杀行为史的相关性

探讨情感性精神障碍患者件相关电位变异的临床意义。方法收集３９例抑郁相和２２例躁狂相患者,以３３例正常人为对照组,记录其事件相关电位Ｐ３００和ＣＮＶ。结论Ｐ３００和ＣＮＶ临床应用价值得到初步证实,自杀行为相关的生物学指标研究中需进一步重视。     

抑郁症诊断的有关问题探讨

目的：探讨抑郁症中有多少具有精神病性症状。方法：采用中国精神疾病分类方案与诊断标准第２版修订版（ＣＣＭＤ－２－Ｒ）中抑郁症的诊断标准进行筛选,再按国际疾病分类第１０版精神与行为障碍分类（ＩＣＤ－１０）研究用诊断标准划分是否伴有精神病性症状,根据研究用诊断标准（ＲＤＣ）区分是否为内源性。结果：①抑郁症绝大多数不伴有精神病性症状,且不同来源样本结果一致。②“内源性”抑郁症和精神病性抑郁症不能等同。③“内源性”与“非内源性”抑郁症中均有重性抑郁症。结论：抑郁症患者大多无精神病性症状。     

伴与不伴精神病性症状的抑郁症临床特征的对照研究

目的探讨伴与不伴精神病性症状(Psychoticsymtoms,PS)的抑郁症患者临床特征的差异。方法对64例伴PS的抑郁症患者(研究组)与118例不伴PS的抑郁症患者(对照组)的人口学特征、主要临床症状及治疗情况进行对照分析。结果研究组的阳性家族史、焦虑激越、自责自罪、绝望和自杀行为等出现率显著高于对照组(P<0.05或P<0.01),研究组的自杀危险性为对照组的2.2倍。结论伴PS的抑郁症可能是抑郁症的一个独特的亚型,通常需要抗抑郁药物与抗精神病或电痉挛(ECT)联合治疗。
