    Efficacy of amisulpride in treating primary negative symptoms in first-episode psychosis: a pilot study

    HUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 8 2006
    Brendan P. Murphy
    Abstract Objective Negative symptoms are debilitating and associated with poor role functioning and reduced quality of life. There is a paucity of research on antipsychotic efficacy against the primary negative symptoms, particularly in first-episode psychosis (FEP). We undertook a prospective, open-label pilot trial to investigate the use of amisulpride in the treatment of young people with FEP characterised by primary negative symptoms. Method Twelve male and two female first-episode patients with primary negative symptoms (aged 16,26) were commenced on low-dose amisulpride (mean 250,mg/day) and followed-up over a 6-month period. Primary outcome measures were the Scale for the Assessment of Negative Symptoms (SANS), the Quality of Life Survey (QLS) and their respective subscales. Results For the 12 completers there was a statistically significant improvement in SANS summary score (p,=,0.036), Affective Flattening subscale global score (p,=,0.046), QLS total score (p,=,0.021), QLS subscales of Instrumental Role (p,=,0.018) and Intra-psychic Foundations (p,=,0.009) from baseline to week 24. Conclusions Amisulpride appears to be associated with less severe negative symptoms and improved quality of life. Generalisabilty of the findings is limited by the small sample size and open-label design of our study, however the positive findings suggest that further controlled trials are warranted.

    Association between feasibility of discharge, clinical state, and patient attitude among inpatients with schizophrenia in Japan

    PSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 3 2009
    Yoshio Mino md
    Aim:, There have been some studies on the feasibility of discharging mentally ill inpatients from mental hospitals. The purpose of the present study was to investigate how a psychiatrist judges whether an inpatient can be discharged. Methods:, A survey regarding such judgments on discharge was conducted involving 549 inpatients with schizophrenia with a hospital stay of ,1 year. Relationships between psychiatrist judgments on discharge and the Brief Psychiatric Rating Scale (BPRS), Scales for the Assessment of Negative Symptoms (SANS), Global Assessment Scale (GAS), patient attitude to discharge, and other variables were investigated. A similar analysis was conducted regarding patient attitudes toward discharge. Results:, After controlling for potential confounding factors using multiple logistic regression, the judgments showed significant relationships with BPRS-P, SANS, GAS, and age. Patient attitudes showed significant relationships with the length of the current hospital stay, SANS, and psychiatrists' judgments. Conclusion:, A psychiatrist's judgment regarding discharge is a comprehensive decision that takes into account psychiatric symptoms, social functioning, and age. Such a judgment could also affect a patient's own attitude toward discharge. [source]


    Pharmacological treatment of negative symptoms of schizophrenia: therapeutic opportunity or Cul-de-sac?

    ACTA PSYCHIATRICA SCANDINAVICA, Issue 2 2007
    P. F. Buckley
    Objective:, Negative symptoms of schizophrenia are debilitating and they contribute to poor outcome in schizophrenia. Initial enthusiasm that second-generation antipsychotics would prove to be powerful agents to improve negative symptoms has given way to relative pessimism that the effects of current pharmacological treatments are at best modest. Method:, A review of the current ,state-of-play' of pharmacological treatments for negative symptoms in schizophrenia. Results:, Treatment results to date have been largely disappointing. The evidence for efficacy of second-generation antipsychotics is reviewed. Conclusion:, The measurement and treatment trials methodology for the evaluation of negative symptoms need additional refinement before therapeutic optimism that better treatments for negative symptoms can be realized.

    Negative symptoms of schizophrenia: a problem that will not go away

    ACTA PSYCHIATRICA SCANDINAVICA, Issue 1 2007
    S. M. Stahl
    Objective:, Negative symptoms of schizophrenia are a common, enduring, and debilitating component of the psychopathology of schizophrenia. Although efforts thus far to elucidate a distinct schizophrenia subtype based upon negative symptoms have yielded mixed results, there are nevertheless neurobiological correlates of the negative symptom typology. Method:, A review of nosology, typology, and assessment tools for determining core negative symptoms in schizophrenia. Results:, Negative symptoms can be difficult to evaluate objectively. Current rating scales ,capture' key domains of negative symptoms, in spite of considerable overlap between these domains. However, each objective assessment trades off methodological rigor and detail against brevity of assessment and ease of use. Conclusion:, The description of new methods for measuring these devastating symptoms, coupled with the ongoing development of novel antipsychotics and agents that augment antipsychotics have fuelled renewed interest in the evaluation of negative symptoms and optimism that better treatments for negative symptoms can be found.

    Quetiapine versus olanzapine for the treatment of negative symptoms in patients with schizophrenia

    HUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 4 2006
    Pinkhas Sirota
    Abstract Negative symptoms are considered the most debilitating and refractory aspect of schizophrenia, being associated with poor social, occupational and global outcomes. Conventional antipsychotics have limited efficacy against these symptoms and poor tolerability profiles. Atypical antipsychotics are an alternative treatment, and this 12-week, randomised, flexibly dosed study compared the efficacy, safety and tolerability of quetiapine and olanzapine in this regard. Of the 40 patients who entered the study (32 male; 8 female), 19 were randomised to quetiapine (mean dose 637,mg/day, mean treatment duration 80 days) and 21 to olanzapine (mean dose 16,mg/day, mean treatment duration 78 days). Quetiapine and olanzapine were similarly effective: in each treatment group significant improvements at Week 12 were observed for negative symptom scores on the SANS and the PANSS, and for subscale scores of affective flattening and alogia on the SANS. Both treatments were well tolerated in this patient population, with no worsening of extrapyramidal symptoms in either case. Anxiety and insomnia were the most common adverse events (,7% of patients in each group), but were not drug-related. Although this is a small study with limited power, the results support the effectiveness of quetiapine and olanzapine in treating the negative symptoms of schizophrenia.

    Cognitive behavioral therapy of negative symptoms

    JOURNAL OF CLINICAL PSYCHOLOGY, Issue 8 2009
    Dimitri Perivoliotis
    Abstract Negative symptoms account for much of the functional disability associated with schizophrenia and often persist despite pharmacological treatment. Cognitive behavioral therapy (CBT) is a promising adjunctive psychotherapy for negative symptoms. The treatment is based on a cognitive formulation in which negative symptoms arise and are maintained by dysfunctional beliefs that are a reaction to the neurocognitive impairment and discouraging life events frequently experienced by individuals with schizophrenia. This article outlines recent innovations in tailoring CBT for negative symptoms and functioning, including the use of a strong goal-oriented recovery approach, in-session exercises designed to disconfirm dysfunctional beliefs, and adaptations to circumvent neurocognitive and engagement difficulties. A case illustration is provided. © 2009 Wiley Periodicals, Inc. J Clin Psychol: In Session 65:1,16, 2009. [source]


    Early identification of non-remission in first-episode psychosis in a two-year outcome study

    Simonsen E, Friis S, Opjordsmoen S, Mortensen EL, Haahr U, Melle I, Joa I, Johannessen JO, Larsen TK, Røssberg JI, Rund BR, Vaglum P, McGlashan TH. Early identification of non-remission in first-episode psychosis in a two-year outcome study. Objective:, To identify predictors of non-remission in first-episode, non-affective psychosis. Method:, During 4 years, we recruited 301 patients consecutively. Information about first remission at 3 months was available for 299 and at 2 years for 293 cases. Symptomatic and social outcomes were assessed at 3 months, 1 and 2 years. Results:, One hundred and twenty-nine patients (43%) remained psychotic at 3 months and 48 patients (16.4%) remained psychotic over 2 years. When we compared premorbid and baseline data for the three groups, the non-remitted (n = 48), remitted for <6 months (n = 38) and for more than 6 months (n = 207), duration of untreated psychosis (DUP) was the only variable that significantly differentiated the groups (median DUP: 25.5, 14.4 and 6.0 weeks, respectively). Three months univariate predictors of non-remission were being single, longer DUP, core schizophrenia, and less excitative and more negative symptoms at baseline. Two-year predictors were younger age, being single and male, deteriorating premorbid social functioning, longer DUP and core schizophrenia. In multivariate analyses DUP, negative and excitative symptoms predicted non-remission at 3 months, but only DUP predicted at 2 years. Conclusion:, Long DUP predicted both 3 month and 2-year non-remission rates in first-episode psychosis. [source]


    A randomised controlled trial of cognitive behaviour therapy for psychosis in a routine clinical service

    Peters E, Landau S, McCrone P, Cooke M, Fisher P, Steel C, Evans R, Carswell K, Dawson K, Williams S, Howard A, Kuipers E. A randomised controlled trial of cognitive behaviour therapy for psychosis in a routine clinical service. Objective:, To evaluate cognitive behaviour therapy for psychosis (CBTp) delivered by non-expert therapists, using CBT relevant measures. Method:, Participants (N = 74) were randomised into immediate therapy or waiting list control groups. The therapy group was offered 6 months of therapy and followed up 3 months later. The waiting list group received therapy after waiting 9 months (becoming the delayed therapy group). Results:, Depression improved in the combined therapy group at both the end of therapy and follow-up. Other significant effects were found in only one of the two therapy groups (positive symptoms; cognitive flexibility; uncontrollability of thoughts) or one of the two time points (end of therapy: general symptoms, anxiety, suicidal ideation, social functioning, resistance to voices; follow-up: power beliefs about voices, negative symptoms). There was no difference in costs between the groups. Conclusion:, The only robust improvement was in depression. Nevertheless, there were further encouraging but modest improvements in both emotional and cognitive variables, in addition to psychotic symptoms. [source]


    Evaluation of a cognitive behaviourally oriented service for relapse prevention in schizophrenia

    Klingberg S, Wittorf A, Fischer A, Jakob-Deters K, Buchkremer G, Wiedemann G. Evaluation of a cognitive behaviourally oriented service for relapse prevention in schizophrenia. Objective:, There is little work demonstrating the effectiveness of cognitive behaviourally oriented interventions in routine service settings. This pragmatic trial is designed to test the impact of a group treatment service on relapse rates under the conditions of routine health care. Method:, A total of 169 schizophrenia patients were randomly allocated either to a comprehensive cognitive behaviourally oriented service (CBOS) or to treatment as usual (TAU). The primary outcome is the time until the first relapse after discharge from hospital. Relapse was defined as an increase in positive or negative symptoms as assessed with the Positive and Negative Syndrome Scale. Survival analysis has been conducted up to the 6-month assessment. Results:, The mean time to relapse after discharge from hospital in the CBOS group was significantly longer than in the TAU group (log rank test, P = 0.033). This was due to less exacerbations regarding negative symptoms in the CBOS condition (log rank test, P = 0.014). The number of social contacts was improved in the CBOS group only. Conclusion:, The CBOS intervention appears to be beneficial in reducing early negative symptom exacerbations. [source]


    Achieving symptomatic remission in out-patients with schizophrenia , a naturalistic study with quetiapine

    T. Wobrock
    Objective:, Symptomatic remission was defined as a score of mild or less on each of eight key schizophrenia symptoms on the Positive and Negative Syndrome Scale (PANSS-8). To evaluate the symptomatic remission criterion in clinical practice and to determine predictors for achieving symptomatic remission, a 12-week non-interventional study (NIS) with quetiapine was conducted in Germany. Method:, For the comparison of patients with and without symptomatic remission, sociodemographic and clinical variables of 693 patients were analyzed by logistic regression for their predictive value to achieve remission. Results:, Four hundred and four patients (58.3%) achieved symptomatic remission after 12 weeks' treatment with quetiapine. Remission was significantly predicted by a low degree of PANSS-8 total score, PANSS single items blunted affect (N1), social withdrawal (N4), lack of spontaneity (N6), mannerism and posturing (G5), and low disease severity (CGI-S) at baseline. Predictors of non-remission were older age, diagnosis of schizophrenic residuum, multiple previous episodes, longer duration of current episode, presence of concomitant diseases, and alcohol abuse. Conclusion:, This study demonstrated that the majority of schizophrenia out-patients achieved symptomatic remission after 12 weeks treatment and confirms the importance of managing negative symptoms in order to achieve disease remission.

    Prevalence and correlates of comorbidity 8 years after a first psychotic episode

    ACTA PSYCHIATRICA SCANDINAVICA, Issue 1 2007
    S. Farrelly
    Objective:, While rates and correlates of comorbidity have been investigated in the early course of psychosis, little is known about comorbidity in the medium-to-longer term or its relationship with outcome. Method:, A total of 182 first-episode psychosis (FEP) patients who met DSM-IV criteria for a current psychotic disorder 8 years after index presentation were grouped according to concurrent comorbidity [no concurrent axis I disorder; concurrent substance use disorder (SUD); other concurrent axis I disorder; concurrent SUD and other axis I disorder]. Outcomes were compared between groups controlling for relevant covariates. Results:, As much as 39% met criteria for one or more concurrent axis 1 diagnoses. Comorbidity was associated with greater severity of general psychopathology, but not with measures of functioning, treatment or negative symptoms. Conclusion:, Specific combinations of comorbid disorders may influence patterns of psychotic symptomatology. Routine examination of axis I disorders is warranted in the ongoing management of psychosis. [source]

    An exploratory open-label trial of aripiprazole as an adjuvant to clozapine therapy in chronic schizophrenia

    ACTA PSYCHIATRICA SCANDINAVICA, Issue 2 2006
    D. C. Henderson
    Objective:, We conducted this 6-week open-label trial to examine the effects of adjunctive aripiprazole in clozapine-treated subjects on weight, lipid and glucose metabolism, as well as positive and negative symptoms of schizophrenia. Method:, Ten clozapine-treated subjects received aripiprazole augmentation; eight completed the 6-week trial and two ended at week 4. Eighty percent were male, the mean age was 38.7 ± 8.9 years and the mean clozapine dose was 455 ± 83 mg daily. Results:, There was a significant decrease in weight (P = 0.003), body mass index (P = 0.004), fasting total serum cholesterol (P = 0.002) and total triglycerides (P = 0.04) comparing baseline to study endpoint. There was no significant change in total Positive and Negative Syndrome Scale scores. Conclusion:, This combination may be useful for clozapine-associated medical morbidity and must be studied in placebo-controlled double-blind randomized trials to determine efficacy and safety.

    L. Wong
    The Early Psychosis Prevention and Intervention Centre (EPPIC) is a comprehensive, specialized treatment service for individuals residing in the western metropolitan region of Melbourne who are experiencing their first psychotic episode. A subprogramme of EPPIC, the Treatment Resistance Early Assessment Team (TREAT), has been developing a framework for the management of individuals experiencing ,prolonged recovery' in early psychosis. TREAT is a consultation team that provides technical assistance to clinicians within EPPIC, comprising senior clinicians with expertise in the biopsychosocial treatment of early psychosis and persisting positive and negative symptoms. A system has recently been set up within the TREAT framework to routinely assess clinical and functional outcomes of these clients using standardized instruments. Case managers are trained to conduct assessments at multiple timepoints over the duration of their clients' treatment at EPPIC. A summary will be presented on the current sample (n=15) and examples of clinician and client feedback reports will be illustrated. Discussion is also provided on the development of training, procedures and materials to enhance integration of clinician and client outcome measures into routine clinical practice. [source]


    Diagnoses at the first psychotic episode and cognitive functioning

    ACTA PSYCHIATRICA SCANDINAVICA, Issue 2002
    J. Addington
    Objectives, To determine the relationship between diagnosis and cognitive functioning in a first-episode sample. Methods, 175 subjects were diagnosed (SCID) on admission to a comprehensive treatment programme for early psychosis and 1 year later. Symptoms (PANSS), social functioning and cognitive functioning (using a comprehensive cognitive battery) were assessed initially and at 1 year. Subjects were divided into three groups: (1) Stable diagnosis of schizophrenia over 1 year (n=84). (2) Initial diagnosis of schizophreniform, brief psychotic disorder, substance induced psychosis or psychosis NOS but who met criteria for schizophrenia at 1 year (n=49) and (3) Stable diagnosis over 1 year of schizophreniform, brief psychotic disorder, substance induced psychosis or psychosis NOS (n=44). Results, There were significant differences amongst the three groups at both assessment periods in positive and negative symptoms and social functioning. There were no differences amongst the groups in cognitive functioning. Conclusions, Individuals with psychotic disorders who do not go on to develop schizophrenia do not differ significantly in neurocognition from those who do develop schizophrenia, although they may have advantages in other areas.

    Insight in early psychosis: a 1 year follow-up

    ACTA PSYCHIATRICA SCANDINAVICA, Issue 2002
    A. Mintz
    Insight is an important prognostic indicator in early psychosis, as its presence can enhance treatment compliance, thus reducing the risk of clinical deterioration. The Calgary Early Psychosis Programme (EPP) is a comprehensive treatment programme for individuals experiencing their first episode of psychosis. Purpose, (i) to examine insight on admission and determine if change occurred in the first year of treatment and (ii) to determine if insight was associated with other symptoms. Methods, Participants were 180 consecutive admissions to EPP who completed a 1-year follow-up. Insight, positive and negative symptoms were measured with the PANSS. Depression was measured with the Calgary Depression Scale. Results, There was a significant improvement in insight from initial to 1-year follow-up (P < 0.001). Insight was positively correlated with positive and negative symptoms (P < 0.001) over time. Insight was negatively correlated with depression (P < 0.001) at the initial assessment. Conclusions, In these first episode patients, there is a significant improvement in insight over time. Insight is significantly related to positive and negative symptoms and to depression in the initial stages of the illness when the presence of depression is notable. [source]


    Are fish oils an effective therapy in mental illness , an analysis of the data

    ACTA PSYCHIATRICA SCANDINAVICA, Issue 1 2000
    Ian D. Maidment
    Objective: To review the literature regarding the use of fish oils in the treatment of psychiatric illness. Method: A Medline search was conducted in September 1999. Results: Five papers have investigated omega-3 fatty acids levels in depression. One study used omega-3 fatty acids as an adjunctive therapy in bipolar disorder. Four studies used fatty acids as an adjunctive therapy in schizophrenia. Conclusion: There is a great deal of current research in this field. While omega-3 fatty acids levels may be lowered in depression, there are no data suggesting that omega-3 fatty acids are effective. One paper indicates that omega-3 fatty acids are effective in bipolar disorders. The data on schizophrenia are conflicting. Omega-3 and omega-6 fatty acids have proved effective. Most of the evidence suggests that the main effect is an improvement in negative symptoms. One recent study showed that omega-3 fatty acids had no effect on negative symptoms. [source]


    Sex differences in schizophrenia, a review of the literature

    ACTA PSYCHIATRICA SCANDINAVICA, Issue 401 2000
    Dr. Alice Leung M.D.
    Objective: To comprehensively and critically review the literature on gender differences in schizophrenia. Method: An initial search of MEDLINE abstracts (1966,1999) was conducted using the terms sex or gender and schizophrenia, followed by systematic search of all relevant articles. Results: Males have consistently an earlier onset, poorer premorbid functioning and different premorbid behavioral predictors. Males show more negative symptoms and cognitive deficits, with greater structural brain and neurophysiological abnormalities. Females display more affective symptoms, auditory hallucinations and persecutory delusions with more rapid and greater responsivity to antipsychotics in the pre-menopausal period but increased side effects. Course of illness is more favorable in females in the short- and middle-term, with less smoking and substance abuse. Families of males are more critical, and expressed emotion has a greater negative impact on males. There are no clear sex differences in family history, obstetric complications, minor physical anomalies and neurological soft signs. Conclusion: This review supports the presence of significant differences between schizophrenic males and females arising from the interplay of sex hormones, neurodevelopmental and psychosocial sex differences.

    At-risk mental state (ARMS) detection in a community service center for early attention to psychosis in Barcelona

    EARLY INTERVENTION IN PSYCHIATRY, Issue 3 2010
    Yanet Quijada
    Abstract Aim: To describe the strategy and some results in at-risk mental state (ARMS) patient detection as well as some of the ARMS clinical and socio-demographical characteristics. The subjects were selected among the patients visited by an Early Care Equipment for patients at high risk of psychoses, in Barcelona (Spain) during its first year in operation. Methods: Descriptive study of the community,team relations, selection criteria and intervention procedure. Description of patient's socio-demographic and symptomatic characteristics according to the different instruments used in detection and diagnoses, taking account of four principal origins of referrals: mental health services, primary care services, education services and social services. Results: Twenty of 55 referred people fulfilled the at-risk mental state criteria, showing an incidence of 2.4 cases per 10 000 inhabitants. They were mainly adolescent males referred from health, education and social services. Overall, negative symptoms were predominant symptoms and the more frequent specific symptoms were decrease of motivation and poor work and school performance, decreased ability to maintain or initiate social relationships, depressed mood and withdrawal. Conclusions: It is possible to detect and to provide early treatment to patients with prodromal symptoms if the whole matrix of the community , including the social services , contributes to the process. The utilization of a screening instrument and a two-phase strategy , the second carried out by the specialized team , seems to be an appropriate approach for early psychosis and ARMS detection.

    Early adolescent cannabis exposure and positive and negative dimensions of psychosis

    ADDICTION, Issue 10 2004
    N. C. Stefanis
    ABSTRACT Aims To investigate the effect of exposure to cannabis early in adolescence on subclinical positive and negative symptoms of psychosis. Design Cross-sectional survey in the context of an ongoing cohort study. Setting Government-supported general population cohort study. Participants A total of 3500 representative 19-year olds in Greece. Measurements Subjects filled in the 40-item Community Assessment of Psychic Experiences, measuring subclinical positive (paranoia, hallucinations, grandiosity, first-rank symptoms) and negative psychosis dimensions and depression. Drug use was also reported on. Findings Use of cannabis was associated positively with both positive and negative dimensions of psychosis, independent of each other, and of depression. An association between cannabis and depression disappeared after adjustment for the negative psychosis dimensions. First use of cannabis below age 16 years was associated with a much stronger effect than first use after age 15 years, independent of life-time frequency of use. The association between cannabis and psychosis was not influenced by the distress associated with the experiences, indicating that self-medication may be an unlikely explanation for the entire association between cannabis and psychosis. Conclusions These results add credence to the hypothesis that cannabis contributes to the population level of expression of psychosis. In particular, exposure early in adolescence may increase the risk for the subclinical positive and negative dimensions of psychosis, but not for depression. [source]


    The PIP5K2A and RGS4 genes are differentially associated with deficit and non-deficit schizophrenia

    GENES, BRAIN AND BEHAVIOR, Issue 2 2007
    S. C. Bakker
    Several putative schizophrenia susceptibility genes have recently been reported, but it is not clear whether these genes are associated with schizophrenia in general or with specific disease subtypes. In a previous study, we found an association of the neuregulin 1 (NRG1) gene with non-deficit schizophrenia only. We now report an association study of four schizophrenia candidate genes in patients with and without deficit schizophrenia, which is characterized by severe and enduring negative symptoms. Single-nucleotide polymorphisms (SNPs) were genotyped in the DTNBP1 (dysbindin), G72/G30 and RGS4 genes, and the relatively unknown PIP5K2A gene, which is located in a region of linkage with both schizophrenia and bipolar disorder. The sample consisted of 273 Dutch schizophrenia patients, 146 of whom were diagnosed with deficit schizophrenia and 580 controls. The strongest evidence for association was found for the A-allele of SNP rs10828317 in the PIP5K2A gene, which was associated with both clinical subtypes (P = 0.0004 in the entire group; non-deficit P = 0.016, deficit P = 0.002). Interestingly, this SNP leads to a change in protein composition. In RGS4, the G-allele of the previously reported SNP RGS4-1 (single and as part of haplotypes with SNP RGS4-18) was associated with non-deficit schizophrenia (P = 0.03) but not with deficit schizophrenia (P = 0.79). SNPs in the DTNBP1 and G72/G30 genes were not significantly associated in any group. In conclusion, our data provide further evidence that specific genes may be involved in different schizophrenia subtypes and suggest that the PIP5K2A gene deserves further study as a general susceptibility gene for schizophrenia.

    Zhen-hua Chen
    Abstract Objective To evaluate the effects of warm-supplementing kidney yang (WSKY) capsule added on risperidone on cognition in chronic schizophrenic patients. Methods A randomized, double-blind, placebo-controlled, multi-center clinical trial was conducted. All 200 patients who met the DSM-IV diagnostic criteria for schizophrenia were randomly assigned to double-blind treatment with WSKY capsule (n,=,100) or placebo (n,=,100) added on risperidone for 8 weeks. The primary outcome measure was the cognitive function assessment assessed by the classic form of the Wisconsin Card Sorting Test (WCST) at baseline and week 8. The secondary outcome measures were assessed including the positive and negative symptoms scale (PANSS), the social disability screening schedule (SDSS), and the Hamilton rating scale for depression (HAM-D-17) at baseline, week 2, week 4, and week 8. The extrapyramidal side effects were assessed each week using the abnormal involuntary movement scale (AIMS) and rating scale for extrapyramidal side effects (RSESE), while adverse events were assessed using treatment emergent symptoms scale (TESS) as additional indicators of tolerability throughout the trial. Results The response rates of the WSKY group for the number of completed categories (CC), errors responses number (ER), perseveringly errors responses number (PER), and conceptual level (CL) of WCST assessment were significantly higher than those of placebo. The reduction in the SDSS score from baseline to endpoint was significantly greater in the WSKY group than those in the placebo. There were no significant differences in the response rates for the correct responses number, perseveringly responses number (PR) of WCST between the treatment groups. The improvements in the WCST indexes, PANSS score, HAM-D-17 score were no significant differences from baseline to endpoint between the two groups at week 8.There were no significant differences in AIMS, RSESE, and TESS compared patients treated with WSKY capsule with those in placebo during treatment. Conclusion WSKY capsule added on risperidone may improve cognitive function, social function of the chronic schizophrenic patients, and the WSKY safely during treatment.

    Abstract Objective Negative symptoms are debilitating and associated with poor role functioning and reduced quality of life. There is a paucity of research on antipsychotic efficacy against the primary negative symptoms, particularly in first-episode psychosis (FEP). We undertook a prospective, open-label pilot trial to investigate the use of amisulpride in the treatment of young people with FEP characterised by primary negative symptoms. Method Twelve male and two female first-episode patients with primary negative symptoms (aged 16,26) were commenced on low-dose amisulpride (mean 250,mg/day) and followed-up over a 6-month period. Primary outcome measures were the Scale for the Assessment of Negative Symptoms (SANS), the Quality of Life Survey (QLS) and their respective subscales. Results For the 12 completers there was a statistically significant improvement in SANS summary score (p,=,0.036), Affective Flattening subscale global score (p,=,0.046), QLS total score (p,=,0.021), QLS subscales of Instrumental Role (p,=,0.018) and Intra-psychic Foundations (p,=,0.009) from baseline to week 24. Conclusions Amisulpride appears to be associated with less severe negative symptoms and improved quality of life. Generalisabilty of the findings is limited by the small sample size and open-label design of our study, however the positive findings suggest that further controlled trials are warranted.

    Quetiapine versus olanzapine for the treatment of negative symptoms in patients with schizophrenia

    Abstract Negative symptoms are considered the most debilitating and refractory aspect of schizophrenia, being associated with poor social, occupational and global outcomes. Conventional antipsychotics have limited efficacy against these symptoms and poor tolerability profiles. Atypical antipsychotics are an alternative treatment, and this 12-week, randomised, flexibly dosed study compared the efficacy, safety and tolerability of quetiapine and olanzapine in this regard. Of the 40 patients who entered the study (32 male; 8 female), 19 were randomised to quetiapine (mean dose 637,mg/day, mean treatment duration 80 days) and 21 to olanzapine (mean dose 16,mg/day, mean treatment duration 78 days). Quetiapine and olanzapine were similarly effective: in each treatment group significant improvements at Week 12 were observed for negative symptom scores on the SANS and the PANSS, and for subscale scores of affective flattening and alogia on the SANS. Both treatments were well tolerated in this patient population, with no worsening of extrapyramidal symptoms in either case. Anxiety and insomnia were the most common adverse events (,7% of patients in each group), but were not drug-related. Although this is a small study with limited power, the results support the effectiveness of quetiapine and olanzapine in treating the negative symptoms of schizophrenia.

    Abstract Objective Although negative symptoms are prominent in older patients with schizophrenia, it is unknown whether this pattern is prevalent in healthy participants. The objective of this study was to evaluate whether negative symptoms are present in healthy populations and to determine whether they are linked to illness-related processes or normal aging. Methods A systemic review of 26 studies that have administered negative symptom assessments to healthy participants was conducted. In addition, 213 (age,>,40,years old) healthy participants completed PANSS and SANS ratings at both baseline and 1-year follow-up. One-hundred participants also completed ratings after 3 years. Results Across all reviewed studies, negative symptoms were absent in the majority of participants. Comparable results were found in the current study's large longitudinal evaluation with middle-aged to older adults. Conclusions Taken together, the data suggest that healthy volunteers do not suffer from prominent negative symptoms. This finding is consistent with the hypothesis that the greater prevalence and severity of negative symptoms in older patients is not related to normal aging but to illness-related processes.

    Abstract Objective The quality of life (QOL) for individuals with schizophrenia is determined by a number of factors, not limited to symptomatology. The current study examined lack of insight as one such factor that may influence subjective QOL or functional capacity. It was hypothesized that insight would significantly interact with symptom severity to influence subjective QOL. Insight was not expected to influence the relation between symptom severity and functional capacity. Methods Participants were middle-aged and older outpatients who met diagnostic criteria for schizophrenia or schizoaffective disorder, and subsyndromal depression. Insight, psychopathology, and subjective QOL were assessed via semi-structured interviews and functional capacity was assessed via performance-based measures. Results Insight interacts with negative symptom severity to predict subjective QOL. Severity of negative symptoms and insight contribute directly to functional capacity. Conclusions Individuals with intact insight may be better able to manage their symptoms, resulting in improved QOL. Treatment implications for improving the QOL of middle age and older adults with schizophrenia are discussed. Copyright © 2008 John Wiley & Sons, Ltd. [source]


    The effects of cannabis abuse on the symptoms of schizophrenia: Patient perspectives

    INTERNATIONAL JOURNAL OF MENTAL HEALTH NURSING, Issue 4 2008

    ABSTRACT:, This study explored explanatory models used by individuals with schizophrenia in relation to continuing cannabis abuse. Cannabis is known to exacerbate positive symptoms, compound the effects of negative symptoms, and lead to relapse, having a negative effect upon quality of life. If this is so, why would people choose to continue the drug use? Most previous studies exploring this phenomenon have used quantitative methodology where the questions asked have been preset by the researchers and the subjective experience of the patient has been minimized. Qualitative methodology was utilized in this study in order to give voice to the patients' perspectives, and contribute to the knowledge of the frameworks of meanings employed by patients. The majority of participants in this study did not perceive that they had a mental illness and they held strong beliefs regarding the usefulness of cannabis. They gave explanations for their continuing cannabis use that expanded the understanding from previous studies. These included that they sought the drug effects of cannabis use for clarity of voices, control of symptoms, to feel normal, perceived improvement in cognitive function, reduced psychological pain and increased energy. These beliefs may influence a person's adherence with treatment and their future cannabis use. This research has implications for clinical practice as clinicians may lack insight into the importance of the phenomenological beliefs of a person with schizophrenia. This lack of insight by the clinician into the phenomenological beliefs may impact on the development of a therapeutic relationship. [source]
